Does Humidifier Increase Oxygen? Trust The Answer

We’ve all been through that. Our child gets an upper respiratory tract infection that causes nasal congestion, difficulty breathing through the nose and coughing. This gets worse and worse at night when they (and we) are trying to sleep. What should parents do? Many of us instinctively plug in the humidifier and leave it on in our bedroom at night. Even paediatricians often recommend this. But does that really mean anything?

It is difficult for young children to blow their nose effectively and remove all the mucus when they are sick. In addition to the already lousy feeling of nausea, stuffy noses often disrupt sleep and after a few restless nights everyone in the house feels like a zombie. The winter air is dry due to cold outside temperatures and the use of indoor heating. The dryness can make blowing or coughing up phlegm even more difficult. So it makes sense to add moisture to the air. But as with many things in education and medicine, there is actually not good evidence supporting the use of humidifiers to treat upper respiratory tract infections.

So what’s the damage? In fact, there are many ways that using a humidifier can make things worse:

Allergies and asthma: both dust mites and mold love moist environments. Those with allergies should not use humidifiers, as this can encourage growth and worsen allergy or asthma symptoms.

This can release chemicals into the air that can irritate the upper and lower airways and worsen symptoms. Stick to distilled water.

When used appropriately, using the tips above and following the manufacturer’s instructions, using humidifiers is unlikely to be harmful. There may be some benefit as well, but there are other tricks you can try instead of or in addition to the humidifier.

Nasal Saline: Putting nasal saline sprays or drops directly into the nasal passages is always more effective than diffusing humidified air around a room. This is a safe treatment that can give little ones clear noses (at least temporarily). You know you did it right when snot flies out or a bit of a cough occurs.

This can help relieve irritated nasal mucosa and sore throat. A good test will ensure that the urine is clear. Any color or strong smell indicates that the moisture level is not ideal. Water is perfect – no need to use sugary sports drinks or juices.

As always, your child’s personal doctor is the best source for specific treatment recommendations, but hopefully these tips will help reduce your sleepless nights this winter.

If liquid water were released in a closed system with air at a pressure of 1 bar, part of the water evaporates until the partial pressure of the water reaches the vapor pressure of 23 mbar (at 20°C). Since nitrogen and oxygen do not have a liquid phase at this temperature, the partial pressures add according to Dalton’s law, which means that the total pressure increases to 1.023 bar, while the partial pressure of oxygen remains the same. So you would get the same amount of oxygen.

In an open system like our atmosphere, it’s more complicated. Both the total pressure and the partial pressure would want to balance each other out. What would happen probably depends on the exact dynamics of the atmosphere. But the partial pressures of water and oxygen would still be separate. If the water partial pressure is higher at one point, water molecules migrate from there to places with lower water partial pressure. However, if gas phases act separately, as suggested by Dalton’s law, why should these water molecules take oxygen molecules with them? Of course, given the size of our atmosphere, pressure equalization is not instantaneous. If we neglect the dynamics of the atmosphere, the partial pressure of water at each location would simply add to the total pressure and propagate separately. It’s not clear why the water would actually displace oxygen as the other answers suggest. If it is true that in areas of high humidity the partial pressure of oxygen is usually lower, then this must be due to atmospheric airflow somehow caused by the humidity, which would lower the total pressure. It’s not because water vapor displaces other gases.

There is another problem with this. The air we breathe is heated and humidified through our airways. When it actually reaches our lungs, it is 100% saturated with moisture, so breathing dry air compared to humid air has no effect on the partial pressure of oxygen that reaches our lungs.

Humidifiers: Relieving Skin and Breathing Conditions Humidifiers can alleviate problems caused by dry air. But they need regular grooming. Here are tips to ensure your humidifier doesn’t become a health hazard. By Mayo Clinic staff

Dry sinuses, bloody noses, and chapped lips—humidifiers can help alleviate these well-known problems caused by dry indoor air. And cool mist humidifiers can also help relieve the symptoms of a cold or other respiratory illness.

But be careful: while humidifiers are useful, they can make you ill if they’re not properly maintained or if the humidity stays too high. If you use a humidifier, be sure to check the humidity and keep your humidifier clean. Dirty humidifiers can breed mold or bacteria. If you have allergies or asthma, talk to your doctor before using a humidifier.

What are humidifiers?

Humidifiers are devices that emit water vapor or water vapor to increase the moisture content of the air (humidity). Types of humidifiers include:

Central humidifier. These are installed in heating and air conditioning systems. They are designed to humidify the whole house.

These create a cool mist with ultrasonic vibration. Impeller Humidifier. These humidifiers use a rotating disc to create a cool mist.

These humidifiers use a rotating disc to create a cool mist. Evaporator. Vaporizers use a fan to force air through a wet wick, filter, or belt.

Vaporizers use a fan to force air through a wet wick, filter, or belt. steam vaporizer. Vapor evaporators use electricity to create vapor that cools before exiting the machine. Avoid this type of humidifier if you have children. The hot water in this type of humidifier can cause burns if spilled.

Ideal humidity

Humidity is the amount of moisture in the air. Humidity varies depending on the time of year, the weather, and the location of your home. In general, humidity is higher in summer and lower in winter. Ideally, the humidity in your home should be between 30% and 50%. Humidity levels that are too low or too high can cause problems.

Low humidity can cause dry skin, irritate your nasal passages and throat, and make your eyes itchy.

can cause dry skin, irritate the nasal passages and throat, and make your eyes itchy. High humidity can make your home feel stuffy and can cause condensation on walls, floors, and other surfaces. Condensation can trigger the growth of harmful bacteria, dust mites and mold. These allergens can cause breathing problems and trigger flare-ups of allergies and asthma.

How to measure humidity

The best way to test the humidity in your home is with a hygrometer. This device looks like a thermometer. It measures the humidity in the air. Hygrometers are available at hardware and department stores. When buying a humidifier, you should buy one with a built-in hygrometer that will keep the humidity level in a healthy range (hygrostat).

Humidifier, asthma and allergies

If you or your child have asthma or allergies, talk to your doctor before using a humidifier. Increased humidity can make breathing easier for children and adults with asthma or allergies, especially during a respiratory infection like a cold. But mist from a dirty humidifier or increased growth of allergens caused by high humidity can trigger or worsen asthma and allergy symptoms.

If the air is too humid: dehumidifiers and air conditioners

Just as dry air can be a problem, too humid air can be. When humidity levels get too high – which is common during the summer months – it’s a good idea to take steps to reduce indoor humidity levels. You can reduce humidity by:

Using an air conditioner. Central or window-mounted air conditioners dry the air and keep indoor humidity at a comfortable and healthy level.

Central or window-mounted air conditioners dry the air and keep indoor humidity at a comfortable and healthy level. Using a dehumidifier. These devices collect excess moisture from the air, thereby lowering moisture levels. Dehumidifiers work like air conditioners, without the “cooling” effect. They are often used to dry out damp basements.

Keep it clean: Dirty humidifiers and health problems

Dirty tanks and filters in humidifiers can quickly multiply bacteria and mold. Dirty humidifiers can cause problems, especially for people with asthma and allergies. But even in healthy people, dirty humidifiers can trigger flu-like symptoms or even lung infections if the contaminated mist or vapor is released into the air. Vaporizers and steam vaporizers may release fewer airborne allergens than cool mist humidifiers.

Tips to keep your humidifier clean

To keep humidifiers free from harmful mold and bacteria, follow the manufacturer’s recommended guidelines. These portable humidifier tips may also help:

Use distilled or demineralized water. Tap water contains minerals that can form deposits in your humidifier that encourage bacterial growth. When released into the air, these minerals often appear as white dust on your furniture. It is also possible that you will inhale some minerals that are dispersed in the air. Distilled or demineralized water has a much lower mineral content than tap water. Also, use demineralization cartridges or filters if recommended by the manufacturer.

Blood oxygen content is the amount of oxygen circulating in the blood. Red blood cells carry most of the oxygen, collect it from the lungs and deliver it to all parts of the body. The body closely monitors the level of oxygen in the blood to keep it within a certain range so that there is enough oxygen for the needs of each cell. A person’s blood oxygen level is an indicator of how well the body is distributing oxygen from the lungs to the cells, and it can be important to human health.

Normal and low blood oxygen levels Share on Pinterest Hiraman/Getty Images A healthy blood oxygen level varies between 75 and 100 millimeters of mercury (mm Hg). When arterial blood gas (ABG) test results show an oxygen level below 60 mm Hg, it is considered low by the medical community. In some cases, people with these results may need oxygen supplementation. A level of oxygen in the blood that is too low compared to the average for a healthy person can be a sign of a condition known as hypoxemia. This occurs when the body has difficulty delivering oxygen to all of its cells, tissues and organs.

Oxygen saturation Oxygen saturation refers to the percentage of oxygen in a person’s blood. Medical professionals often use a device called a pulse oximeter for either a quick test or continuous monitoring. The device can be attached to the person’s fingertip. A healthy oxygen saturation is between 95% and 100%. When a person’s levels fall below this range, they may experience symptoms associated with oxygen deprivation, such as difficulty breathing and confusion.

How is the oxygen content in the blood measured? An ABG test is the most effective way to monitor blood oxygen levels. In this test, a sample of blood is taken from an artery, usually in the wrist. This procedure is very accurate but can be a bit painful. Doctors perform ABG tests in a hospital. You can also test yourself at home with a small device called a pulse oximeter. A pulse oximeter is a small clip that often attaches to a finger, although it will work on an ear or toe as well. It measures blood oxygen indirectly by absorbing light through a person’s pulse. Although the pulse oximeter test is easier, faster, and less painful than the ABG test, it is not as accurate. Several factors can affect results including: Dirty fingers

bright lights

darker skin tones

nail polish

poor blood flow to extremities Learn how to choose the best pulse oximeter to buy.

People should see a doctor if they: have severe and sudden shortness of breath

Experiencing shortness of breath at rest

have severe shortness of breath that gets worse during exercise or physical activity

sudden awakening feeling short of breath or choking

are at high altitude and have severe shortness of breath with coughing, rapid heartbeat and fluid retention

Treatment Treatment options for low blood oxygen levels include supplemental oxygen. Physicians may administer oxygen therapy in an office or may prescribe or recommend the use of home oxygen therapy (HOT). A number of devices are available for dispensing and monitoring HOT, but some require a prescription. People can make lifestyle adjustments to reduce symptoms of low oxygen and improve their overall health and quality of life. Changes that are likely to be beneficial include: Quitting smoking

Avoidance of passive smoking

a nutritious diet high in fruits, whole grains, lean proteins, and vegetables

exercise regularly Learn more about a balanced diet.

Outlook Many diseases can lead to low blood oxygen levels. Treating the underlying condition that is responsible for this generally improves blood oxygen levels. People with chronic lung diseases like COPD and people who contract COVID-19 may need regular blood oxygen monitoring. A person with low blood oxygen may also make lifestyle changes such as: B. adjusting their diet and exercise habits. In conjunction with oxygen therapy, these changes could help a person increase their oxygen saturation.

Blood oxygen content: diagram

Oxygen levels are measured by the percentage of oxygen saturation in your blood. This is called the SpO2 reading.

Normal blood oxygen level

For medical purposes, a normal blood oxygen saturation rate of between 95% and 100% is often assumed. However, if your percentage is lower, you may not experience any symptoms.

‘Regarding’ the level of oxygen in the blood

Oxygen levels between 91% and 95% can indicate a medical problem. People in this situation should contact their doctor.

Low blood oxygen levels

The medical definition of low blood oxygen rate is any percentage below 90% oxygen saturation. An oxygen saturation below 90% is very worrying and indicates an emergency. Call 911 right away if you or someone you know has blood oxygen levels that low.

When low oxygen saturation affects your brain

When your oxygen saturation has dropped to 80% to 85%, your brain can be affected by the lack of oxygen. You may also experience vision problems.

cyanosis

The first visible symptom of low blood oxygen, cyanosis, causes a blue discoloration on your skin, especially around your mouth and lips and under your fingernail matrix. This change occurs when your blood oxygen saturation reaches about 67%.

Overview What is hypoxemia? Hypoxemia is when the level of oxygen in the blood is lower than normal. When blood oxygen levels are too low, your body may not function properly. Someone with low blood oxygen is considered hypoxemic. Oxygen enters your blood through the lungs. When you breathe in, oxygen moves from the air through your lungs into small air sacs (alveoli). Blood vessels (capillaries) migrate near the alveoli and absorb the oxygen. Eventually, oxygen gets to your tissues through your blood. Hypoxemia can occur when you can’t breathe in enough oxygen or when the oxygen you breathe can’t get into your blood. Air and blood flow are both important for having enough oxygen in your blood. Because of this, both lung disease and heart disease increase the risk of hypoxemia. Depending on its severity and duration, hypoxemia can result in mild symptoms or death. Mild symptoms are headache and shortness of breath. In severe cases, hypoxemia can impair heart and brain function. It can lead to a lack of oxygen in the organs and tissues of your body (hypoxia). Hypoxemia can occur for a short time and lead to “acute” respiratory failure. In situations where it’s a long-term problem spanning months and years, it may be referred to as “chronic respiratory failure.” Hypoxemia vs Hypoxia: What’s the Difference? You may hear the words hypoxemia and hypoxia interchangeably, but they are not the same thing. The names sound similar because they both involve low levels of oxygen, but in different parts of your body. Hypoxemia is low oxygen levels in your blood and hypoxia is low oxygen levels in your tissues. Hypoxemia can lead to hypoxia and both often but not always occur together. They can be hypoxemic but not hypoxic and vice versa. Who does hypoxemia affect? Any condition that reduces the amount of oxygen in your blood or restricts blood flow can cause hypoxemia. People with heart or lung conditions, such as heart failure, COPD, or asthma, are at increased risk of hypoxemia. Some contagious diseases, such as influenza, pneumonia, and COVID-19, can also increase the risk of hypoxemia.

Symptoms and Causes What are the symptoms of hypoxemia? Hypoxemia symptoms vary by severity and underlying cause. Some hypoxemia symptoms are: Headache.

Difficulty breathing or shortness of breath (dyspnoea).

Rapid heart rate (tachycardia).

Cough.

gasping.

Confusion.

Bluish discolouration of the skin, fingernails and lips (cyanosis). What is the most common cause of hypoxemia? Hypoxemia has many causes, but the most common cause is an underlying disease affecting blood flow or breathing (such as heart or lung disease). Certain medications can slow breathing and lead to hypoxemia. Sleep apnea and mild lung disease can cause nocturnal hypoxemia — when your blood oxygen levels drop during sleep. Staying at high altitudes can also lead to hypoxemia, which is why breathing in the mountains can be difficult. Medical conditions that can lead to hypoxemia include: Acute respiratory distress syndrome (ARDS).

Anemia.

Asthma.

Bronchitis.

Chronic Obstructive Pulmonary Disease (COPD).

Congenital heart defects.

heart failure.

emphysema.

Lung infection.

Pneumothorax (air in the space around your lungs or collapsed lung).

Pulmonary edema (fluid in the lungs).

pulmonary embolism (blood clots in the lungs).

Pulmonary fibrosis (lung scarring).

Pulmonary Hypertension. What are the five causes of hypoxemia? Problems with cardiac and pulmonary function can lead to five categories of conditions that cause hypoxemia: ventilation and perfusion (V/Q) mismatch, diffusive dysfunction, hypoventilation, low ambient oxygen, and right-to-left shunt. Ventilation/Perfusion Mismatch (V/Q) For oxygen to get to your blood, you need both airflow into your lungs (ventilation) and blood flow to your lungs (perfusion) to pick up the oxygen. If any of these don’t work, you end up with plenty of oxygen in your lungs but not enough blood flow to pick it up, or vice versa. This is called ventilation-perfusion or V/Q mismatch. It is usually caused by a heart or lung condition. Diffusion Impairment Even when you have good breath and blood flow, sometimes it’s difficult for oxygen to get from your lungs to your blood vessels – or diffuse (diffusion failure). Diffusion failure can be caused by emphysema, scarring of your lungs, or diseases that affect blood flow between the heart and lungs. Hypoventilation Hypoventilation is when you don’t breathe deeply enough or breathe too slowly. That means not enough oxygen is getting to your lungs. Many lung diseases and some brain diseases can cause hypoventilation. Low Oxygen Area When the air around you doesn’t contain enough oxygen to breathe, your blood can’t get the oxygen it needs to keep your body running. There is less oxygen available in the air at high altitude locations than at lower altitude locations. Right-to-left shunting Deoxygenated blood enters your heart from the right, is pumped to your lungs for oxygen, and then comes back from the left to be pumped into your body. In some people, deoxygenated blood can be pushed to the left side of your heart and get to your tissues without getting oxygen to your lungs first. This is called a right-to-left shunt and is usually caused by an abnormality in your heart.

Diagnosis and Tests How is Hypoxemia Diagnosed? To diagnose hypoxemia, your doctor will perform a physical exam to listen to your heart and lungs. Abnormalities in these organs can be a sign of low blood oxygen. Your doctor can also check if your skin, lips, or fingernails appear bluish. Your provider will run tests to check your oxygen levels, which may include: Pulse oximetry: A sensor slipped over your finger measures the amount of oxygen in your blood. Pulse oximetry is painless and non-invasive. Many doctors routinely use it at every visit.

: A sensor slipped over your finger measures the amount of oxygen in your blood. Pulse oximetry is painless and non-invasive. Many doctors routinely use it at every visit. Arterial blood gas test: A needle is used to draw a sample of blood from your wrist, arm, or groin to measure the level of oxygen in your blood.

: A needle is used to take a blood sample from your wrist, arm or groin to measure the level of oxygen in your blood. Six Minute Walk Test (6MWT): See your exertion oxygen level and how far you can walk on a flat surface in six minutes. This test helps assess lung and heart function.

Management and treatment How is hypoxemia treated? Depending on the underlying cause of the hypoxemia, medication or other treatments may help increase your blood oxygen levels. To increase oxygen levels, your provider may use “supplemental oxygen” via oxygen tanks or oxygen concentrators. Depending on the severity of the disease, these may be needed permanently or only under stress. In the case of severe hypoxemia, particularly acute respiratory distress syndrome, healthcare providers may use a machine that breathes for you (ventilator). If hypoxemia does not resolve, additional medications or therapy may be used, a condition known as refractory hypoxemia. Treatments that focus on the underlying cause may include: bronchodilator or steroid inhalers to help people with lung conditions like COPD.

Medicines to help get rid of excess fluid in your lungs (diuretics).

Continuous positive airway pressure mask (CPAP) for the treatment of sleep apnea.

Supplemental oxygen can be used to treat an ongoing risk of hypoxemia. Oxygen machines vary, but you can expect to get a machine that delivers supplemental oxygen through a breathing mask or small tube (cannula). You can get oxygen at home, with a portable device while traveling, or in the hospital. How do I deal with the symptoms of hypoxemia? If you experience symptoms such as confusion, shortness of breath, rapid heartbeat, or notice that your nails, lips or skin appear bluish, you should see a doctor immediately. You can also check your oxygen levels at home with a pulse oximeter. Hypoxemia should be treated promptly to prevent organ damage in severe cases. COPD, sleep apnea, and other conditions can cause chronic or intermittent hypoxemia with less severe or no symptoms. Talk to your doctor about treating your specific condition to reduce your symptoms and risk of low oxygen levels. What are the complications or side effects of hypoxemia? When your blood is low in oxygen, it can’t deliver enough oxygen to your organs and tissues that need it to keep working (hypoxia). This can damage your heart or brain if it persists over time (such as in nocturnal hypoxemia caused by sleep apnea). Acute cases of hypoxemia can be fatal.

Prevention How can I reduce my risk of hypoxemia? The best way to reduce your risk of hypoxemia is to treat any underlying medical conditions that can lower your blood oxygen levels. If you live with lung or heart disease, talk to your doctor about your concerns and specific ways to lower your risk. Even for people without heart or lung disease, certain medications and situations — like traveling to higher altitudes — can increase your risk of hypoxemia. Ask your provider about any special precautions you need to take when traveling or taking medication. When traveling, allow yourself time to safely adjust to higher altitudes.

Outlook / Prognosis What is the outlook for people with hypoxemia? Depending on the cause, people with hypoxemia may need one-time or ongoing treatment. Your healthcare provider will work with you to treat the condition so you can lead an active, healthy life.

People with low blood oxygen levels can benefit from at-home oxygen therapy to feel more energetic and make everyday life easier.

It’s important to get an oxygen prescription from your doctor to ensure you’re using the right amount of oxygen to get the most benefit.

If you have been prescribed home oxygen, here are 12 tips every home oxygen user should know:

Oxygen therapy can help. Some people with lung diseases don’t get enough oxygen in their blood. Low blood oxygen levels mean vital organs are being deprived of oxygen, which can lead to damage over time. Blood tests will confirm if this is the case. Home oxygen therapy can help people with confirmed low blood oxygen levels by ensuring that enough oxygen is getting to vital organs. In some cases, oxygen therapy at home can also make everyday life easier and more comfortable. Regular medical checks are essential. It’s important to have your oxygen regimen checked by a respiratory specialist at least once a year. If you feel like your condition has changed, make an appointment with your doctor sooner. Do not adjust your oxygen flow rate yourself. Oxygen does not always relieve shortness of breath. There are many reasons why people have difficulty breathing. Home oxygen therapy can relieve shortness of breath in some people, but not in many. Sometimes you need a combination of therapies to relieve shortness of breath. Ask your doctor, respiratory nurse, or physical therapist to explain in detail the benefits you can expect from oxygen. Oxygen is not addictive. Home oxygen therapy is non-addictive and does not weaken your lungs. You get maximum benefits when you use oxygen for the length of time prescribed by your doctor. A range of oxygen equipment is available. Two main types of oxygen equipment are used in Australia. The most common is the oxygen concentrator, which filters nitrogen from the air to provide nearly pure oxygen. Gas cylinders filled with oxygen are also widely available and come in different sizes. The smaller cylinders are light enough to take with you when you leave the house and are often referred to as portable oxygen cylinders. Some oxygen equipment is funded. Many home oxygen users are eligible for government-funded equipment. However, the qualification rules are different in each state. If you need additional equipment, you can buy or rent it directly from an oxygen supplier. Ask your doctor or a member of your health care team for help in choosing the equipment that is best for you. A number of helpful practical tools have been developed to support this booklet. They include equipment checklists and can be found online at: https://lungfoundation.com.au/patient-support/living-with-a-lung-condition/oxygen/ Oxygen is safe to use but can lead to a more intense cause burning. Do not place yourself or your oxygen device near sources of extreme heat, flames, or devices that may produce sparks, including a lit cigarette or e-cigarette. A study in the US has shown that smoking is by far the leading cause of severe burns in people who use oxygen in the home. Carry on with everyday life. Although it may take a while to get used to your oxygen equipment, try to continue with your normal routines as much as possible. Many people don’t need to use their oxygen when driving outside the home. For those who do, the sense of embarrassment about using oxygen equipment in public is usually short-lived. Once your confidence improves, the pros should outweigh any cons. Avoid smoking and staying near smokers. Cigarette smoke is very harmful to the lungs. Quitting smoking is the most effective thing you can do to improve your condition. It is also important to avoid other people’s cigarette smoke. Staying active is good for your health. Regular physical activity is very important for people with lung diseases so that they can more easily cope with everyday activities. Activity doesn’t have to be strenuous. Good activities include walking the dog, going on a trip, or just doing chores around the house. A pulmonary rehabilitation program can also teach you how to move more easily. For information on a program near you, visit https://lungfoundation.com.au/pulmonary-rehabilitation-programs-2/ or call our toll-free Information and Support Center on 1800 654 301. Traveling with oxygen equipment is possible and must be planned. Some of the things to check before booking a trip are: how to properly transport your gear; whether you can use your portable oxygen while traveling; and how to organize an oxygen supply at your destination. You may also need a letter from your doctor confirming that you are fit to travel. Plan what to do in an emergency like a power outage. The most important thing to remember is to try to stay calm and not panic. Although the loss of performance will be annoying, most oxygen users (even those on oxygen 18 hours a day or more) are safe without their oxygen supply for many hours when resting. Call an ambulance if you need urgent help.

You can’t just put a humidifier just anywhere. And that’s not because of feng shui. Properly positioning a humidifier in your home can make a big difference in how well the humidifier is used.

Knowing where to place a humidifier can increase its effectiveness by more than 15%. More importantly, improper placement of a humidifier in a room can affect its function by up to 30%. On top of that, you can unintentionally create a breeding ground for mold.

The biggest mistake when setting up a humidifier is usually to put it in a corner, on the floor, or near a wall. In these cases, we get locally higher humidity readings (say 80% near a humidifier), but the rest of the room still feels dry (say 30% relative humidity). These placement errors result in uneven moisture distribution (humid near the humidifier, dry air everywhere else).

Where should I place my humidifier?

We will cover the 7 golden rules for placing a humidifier in a room. In order to properly place your humidifier, you should at least know the general principles of placing a humidifier in your bedroom, living room, children’s room, etc.

On top of that, we’ve added the bonus tip at the end (this will take a little practice on your part).

We’ll go through these rules one by one for the best spot to place humidifiers, starting with the most important one:

1. The best place for a humidifier is where the most airflow is

We will talk later about putting a humidifier on the table, a bedside table in the bedroom, near plants and so on.

The first general principle for humidifier placement is as follows:

Always place it where the air moves the most.

Each humidifier is a unique source of higher relative humidity (or humidity). In order for moisture to disperse most efficiently in a room or throughout the home, it needs to be placed where we have the greatest airflow.

Air flow is nothing more than air movement. A humidifier humidifies the air in its general environment. If this air isn’t moving, you have a localized room with high humidity, but the rest of the air in the room might still feel a bit dry.

Example: Near a humidifier you see a high humidity of 80%. If this air isn’t moving effectively, chances are that even 6 feet from the humidifier, the humidity in the room is still 30% (aka dry air).

The best practice for placing a humidifier is:

Between a window and a door.

Between a window and another window.

Windows and doors provide entry/exit for air. There is likely to be a small but significant flow of air between a window and a door, which helps to disperse the humidified air from a humidifier throughout the room.

Here’s another example of where to place a humidifier to improve the even distribution of higher relative humidity air:

2. Hold the humidifier 2-4 feet off the ground (put it on a table)

There are several reasons why you shouldn’t place a humidifier directly on the floor or too close to the ceiling. You should find that ideal spot 2-4 feet off the floor and at least 4 feet below the ceiling (especially with high capacity 500+ mL/hr cool mist humidifiers.

Here’s why putting a humidifier on the floor is a bad idea:

You get less airflow to the ground. Down there the air is usually stale, hovering less than 2 to 4 feet above the ground. This increases the likelihood of uneven moisture distribution. spilling on the floor. Humidifiers tend to spill water and leak. To avoid damaging your floor, consider lifting a humidifier off the floor. Pets or children can easily knock over the humidifier when placed on the floor. Of course, cats have also been known to knock things off tables; that’s just their nature.

Now, placing a humidifier close to the ceiling isn’t the smartest move either. This applies in any case; Whether you are trying to figure out where to put a humidifier in your bedroom or where to put a humidifier in the living room.

That’s because most humidifiers expel the humidified air at the top. If you want this water-rich air to get to the ceiling unhindered, you have to worry about the ceiling paint chipping off or worse, mold.

It’s not uncommon to see the black mold on the ceiling above a humidifier that’s over 5 feet off the floor.

The best height for a humidifier is between 2 and 4 feet. There it gets adequate airflow, won’t damage floors, is less likely to be knocked over, and is still far enough from the ceiling not to cause damage to ceiling paint or mold growth.

This means that you should place a humidifier on a table (either a 2-foot low or a 4-foot high table) in the middle of the room.

Of course, it’s always a good idea to put a humidifier on a towel because of potential leaks.

3. Place a humidifier near heaters (places with the lowest relative humidity)

Even if you don’t use a humidifier, some spaces in your room or house will have a lower relative humidity than the rest of the room.

Example: Areas near heat sources (near heaters) typically have lower relative humidity (let’s say 30%) in winter. Even if the room still has an average relative humidity of 40%, you should start by increasing the humidity where it is lowest.

It often makes sense to place a humidifier near a space heater. This can be a space heater, baseboard heaters or even a mini split heat pump air handler or fan heater. These rooms are known for three things:

Higher air temperature. Due to the higher temperatures, the air feels particularly dry.

Due to the higher temperatures, the air feels particularly dry. Lower relative humidity. Heated air can usually hold less moisture.

Heated air can usually hold less moisture. Good airflow from warm air rising to the ceiling.

As we can see, we need to increase humidity near these heat sources. In addition, placing a humidifier near a heat source will ensure adequate airflow due to the warm air rising.

This means that the humidifier will first humidify the air that needs the most moisture, and the humidified air will be propelled slightly through a room due to the rising airflow of the heated air. This ensures a more even distribution of the moisture generated by the humidifier.

4. Don’t put a humidifier in a corner (Bedroom humidifier placement mistake)

Putting a humidifier in a corner is a no-go. There are two main reasons for this:

Corners receive a minimal amount of airflow. A humidifier in a corner humidifies your air very unevenly.

A humidifier in a corner humidifies your air very unevenly. As a rule, corners already have an above-average relative room air humidity. Example: That’s why you first see mold (also black mold) in the corners.

In general, you should place a humidifier in the middle of the room if possible. That’s easy to handle if you put a humidifier in a living room.

what about bedrooms Where should you place a humidifier in the bedroom?

In a bedroom, the no-corners rule is most obvious. We can’t put a humidifier in the middle of the bedroom; there is the bed. On one size there are usually closets, and on the other side of the bedroom we have two corners.

Because of this, many homeowners think it would be great if you could take advantage of that bedroom nook and fill it with a humidifier. This is not the best humidifier placement for a bedroom.

In a bedroom, place smaller humidifiers on a bedside table, and larger humidifiers for large rooms on a table or even a chair. Make sure the distance between you and the humidifier is at least 3 feet; You may need to move a bedside table slightly away from the bed.

A list of the best humidifiers for bedrooms can be found here.

5. Place a humidifier near plants (they usually need extra humidity)

according to dr Leonard Perry of the University of Vermont, “Houseplants thrive best at 70 to 80 percent relative humidity, a level that is often difficult to maintain indoors.”

Pretty much any house plan will welcome the proximity of a humidifier. Placing a humidifier near houseplants is the most obvious rule for humidifier positioning.

This is especially true in winter when humidity can often fall below 40%.

Now you might be thinking, “Hey, I have a humidifier, what difference does it make if I put it near the plants or not?” The humidity should be the same throughout the room.”

Quite a big difference actually. In most cases, humidifiers do not ensure an even distribution of moisture. For example, an air conditioner can create an even temperature distribution (let’s say from 20°C to 22°C). An average room humidifier will ensure that the humidity level is between 50% and 80%; that’s quite a range.

We want the higher 80% of indoor relative humidity to be where the plants are, right? The easiest way to achieve this is to place a humidifier near the plants.

6. Don’t put a humidifier near electronic devices (electricity and water don’t mix well)

We all know that water can damage electronic devices. Imagine hanging an iPhone in close proximity to a humidifier. The moisture would suck through all the iPhone jacks and eventually damage the phone or even ruin it completely.

The same applies to laptops, radios, stereo systems, Alexas & Co. Make sure that you do not expose the expensive electronics to above-average humidity in the immediate vicinity of an air humidifier.

Also, when setting up a humidifier, make sure that the jet of moisture (either cold mist or warm mist) is not blowing into a laptop, desktop, phone, etc. This stream of moisture is typically 100% relative humidity and can damage any electronic device if you expose it to the stream long enough.

Also, watch out for electrical devices. Outlets and extension cords with multiple outlets should not be near a humidifier. Standard outlets are usually elevated off the ground and flooding does not cause an immediate problem there.

The power strip extension cords are another matter; Placing a humidifier over an extension cord can allow moisture (or leaking water) to drip into the outlet extension cords and damage your devices.

7. Always try to put a humidifier in the middle of the room

If you want the humidity to be as evenly distributed throughout the room as possible, try placing it in the middle of the room.

Placing a humidifier next to a wall is a bad idea. The column of moisture from the humidifier can damage your wall (wall paint and water don’t mix).

Placing a humidifier in the center of the room allows for adequate airflow and relative humidity distribution. This is especially true for the 360 ​​degree moisture release humidifiers.

Bonus tip: Place a humidifier in the room

As we know, the biggest problem when positioning the humidifier is ensuring an even distribution of moisture. You can maximize this distribution by elevating the humidifier near the center of the room, etc.

You can further maximize the humidifier’s effectiveness by moving the humidifier around. Yes, you will have to unplug and plug the humidifier back in if you move it, but you can vastly increase humidity level uniformity by repositioning the humidifier every few hours or so.

If you find that a spot in a room still feels dry, simply place the humidifier there and let it do its thing.

Hopefully you can now take full advantage of the humidifier by knowing how to properly position it in your home.

Protect your health and sleep better with a humidifier

It’s a small change, but using a humidifier at night can make a big difference. It can help you sleep better and help your body stay healthy. In both winter and summer, maintaining a relative humidity level between 40 and 60% indoors has a number of surprising benefits.

Can sleeping with a humidifier help me stay healthy?

Using a humidifier while sleeping has some obvious health benefits. For example, you’ll find you’re less likely to struggle with dry skin, sinus problems, bloody noses, and chapped lips. You may also feel constipation relief when you have a cold.

There are less obvious benefits too. When air dries up the nasal passages, it becomes harder for the cilia to filter bacteria, germs, dust, and pathogens and prevent them from entering your airways. In this way, using a humidifier supports your body’s defenses against viruses and other diseases.

Watch this video to learn more about the benefits of humidifiers.

Can increasing humidity levels reduce the risk of contracting Covid-19?

A recent study showed that reducing humidity levels by just 10% could double the rate of transmission of the coronavirus. This is because viruses can survive longer and infectious particles can float longer in drier air. At higher humidity levels, aerosol droplets spread faster, fall to the ground and have fewer opportunities to be inhaled by healthy people.

In addition to strengthening the body’s natural barriers against disease, humid air makes it harder for viruses to survive and spread. Maintaining indoor relative humidity in this 40–60% range helps prevent aerosol particles from being carried over long distances and facilitates transmission between people.

When should I sleep with a humidifier?

Dry air can be dangerous at any time of the year.

winter

In winter, people spend more time indoors and homes are heated, making indoor air drier. As described above in relation to the coronavirus, cold and influenza viruses survive and become more widespread in dry winter conditions. For this reason, increasing indoor humidity levels during high heat helps prevent the spread of common seasonal airborne viruses.

In addition, a humidifier moistens the nasal and upper respiratory tract when the air is dry. This can help you breathe easier if you have a runny nose, chest congestion, cough, or sore throat.

Summer

The indoor air is unnaturally dry, and not just in winter. In summer, air conditioning removes moisture from the air. This causes the air in the house to become dry and causes many of the same health problems. Conditioned air can dry out your sinuses, nasal passages, and throat when you sleep, leading to inflammation and swelling in these delicate tissues.

Using a humidifier while sleeping in the summer will help relieve these symptoms of dry air, as well as seasonal allergies. The cool mist can counteract pollen and mold when they are at their peak.

Why do I sleep better with a humidifier?

Summer and winter health benefits aside, some people find that they simply sleep better with a humidifier running at night. Why is this?

Firstly, because maintaining optimal humidity increases your overall comfort level when you fall asleep. It can help relieve an itchy, irritated throat. Second, a humidifier creates a “white noise” effect while it’s running overnight. The low hum of a fan or humidifier has been shown to help people calm down and nod off.

How Does Sleeping With A Humidifier Reduce Snoring?

When the mouth, nasal cavities, palate, and airways dry out, snoring tends to get worse. The vibrations of these dry tissues caused by each inhalation and exhalation can amplify the sound of snoring. Turning on a humidifier before bed can help reduce loud snoring by delivering more moisture to these tissues.

How can I improve indoor air quality for my whole house?

If you want the same benefits of a small bedroom humidifier throughout the house, consider adding a whole house humidifier. This device works in tandem with your regular furnace and central heating system to deliver more humid air to any room.

Humidifiers have become an essential gadget in bedrooms, especially in winter. Many people even leave the heating on at night to stay warm and cozy while they sleep. However, this has several disadvantages, such as B. dried up air, which leads to a variety of problems. This is where humidifiers come in.

However, many people wonder if they should run a humidifier all night and what that might do for their health. Don’t worry, we wrote this article to help you understand why humidifiers are important for your health in winter and how you can optimize their use to wake up fresh in the morning.

People living in parts of the world with arid climates often look for a respite when using humidifiers. Humidifiers are small devices that are placed on the wall or on a bedside table and keep the air in a room moist instead of dry. Humidifiers typically have small water dispensers that create water vapor that purifies the air in the room.

However, not only people who live in hot and dry areas are fond of humidifiers. Many people with radiators in the room know the pain of waking up with a dry throat and stuffy nose. Dry air in the room can lead to various problems, such as dry skin, dry throat, persistent cough, and dry and chapped lips.

People find it easier to enjoy the cool night in bed with a humidifier running, keeping the air moist and comfortable. Additionally, people with asthma and other breathing problems may find waking up to humid air beneficial. People with neurodermatitis regularly fight against dry and sore skin, which is rarely the case with a good humidifier. A study shows that low humidity can help influenza virus survival, suggesting humidifiers are the best means of combating it.

However, as with any device, many people have concerns about leaving an electronic device on all night.

With that in mind, we created this article to give you the most reliable answer.

Can your humidifier run all night?

This question confuses many people as most electronic devices cannot be left on for long periods of time. Nevertheless, you can go to sleep with your humidifier. It vaporizes the air so you can sleep peacefully and soundly.

There are different types of humidifiers such as: B. Evaporative moisturizers (cold mist), warm mist humidifiers, and all-home humidifiers. Today most people use portable and compact humidifiers because they are more affordable and easier to implement and maintain.

On the other hand, all-home humidifiers make more sense in large and smart homes that come with thermostats and other smart devices that can intelligently set and adjust the appropriate humidity levels in your home.

Finally, the ultrasonic humidifiers are also very popular among home humidifiers and offer more advantages than the models mentioned above.

The most commonly used humidifiers are cool mist and warm mist humidifiers, so people are most concerned about leaving them on for 24 hours.

People living with small and curious children prefer to use cool mist humidifiers to avoid hot water accidents inside the device. Those worried about bacteria, mold, and general humidifier maintenance are better off using warm mist humidifiers.

While humidifiers are safe to use throughout the night and even days, there are certain conditions in which they can function to maintain their functionality and remain safe for your household.

Humidifiers are safe under certain conditions

Now let’s look at these specific conditions and see how you can improve the environment you sleep in to make the most of humidifiers, keep your room humid, and provide great sleep quality.

Condition 1: It needs a hygrometer to warn you about excessive humidity

You must ensure that the humidity in your room is between 30% and 50%. While most better brand humidifiers come with a built-in sensor that can measure humidity, some cheaper options don’t. That’s why you need a hygrometer.

A hygrometer is an instrument that can measure the humidity in your home. Most homes have it, but some don’t, which is why it’s important to keep an eye on humidity levels. High humidity can make it difficult for you to breathe, especially if a baby is in the same room where the humidifier is placed.

Although hydration helps keep your skin and body hydrated, high humidity can be risky as it can lead to dehydration. It can also cause bacteria, mold, mildew and dust mites to thrive in humidity levels above 60%. It is well known that 40% to 50% humidity can kill all types of microbes, so keeping it low is important.

Tips: Use humidifiers that auto shut off when humidity reaches 50% or anywhere between 40% and 50%.

If you are considering a humidifier, make sure it has a hygrometer built in.

Place humidifiers near the driest area in the house or apartment.

If your humidifier doesn’t have a hygrometer, invest in one.

Condition 2: You pay attention to the humidity

While all devices are rapidly becoming intelligent, they are not omniscient. It is important to be attentive and to regularly check the values ​​of the device. If you feel that the room or the whole apartment is getting too humid, it is important to change the levels before it becomes an ideal safe ground for mold to grow.

Tips: Check the hygrometer during the day.

Set an alarm on the device when the humidity gets too high.

If you find that your unit is having trouble in the morning and readings are higher than they should be, consider replacing it.

Condition 3: You are not using tap water to power the humidifier

Tap water is rich in minerals and sometimes even metals and other compounds that we cannot normally see or taste. However, tap water causes a build-up of plaque that can lead to the development of bacteria and other microbes, as well as mold. As a result, you may notice white spots and spots of other colors surrounding your furniture in the house.

Tips: Invest in distilled or demineralized water that is pure and won’t foul your filters.

Read the specification and user manual that show what type of water you should use. Usually, different cleaners can use purified, distilled or demineralized water.

Condition 4: You must clean the filter several times a week

When you use a humidifier, you breathe in the air that has been purified from the water dispenser it contains. Nevertheless, you should clean the water dispenser mentioned regularly in order to be able to breathe healthy air. When we open and close the tank, small pieces of air, dust or bacteria get inside, and after a few days they can multiply, causing dust and mold to spread in the air.

Tips: Clean carefully and thoroughly at least 1 to 3 times a week.

If your humidifier has a filter, clean it as well as the water tank.

According to the EPA, you should use 3% hydrogen peroxide to clean your humidifier.

Read the user manual, which will tell you how to replace the filter after some time. Many companies offer replacement filters in packages, although after a while you may need to buy a new one.

Condition 5: Replace the water frequently

We know that replacing the water and finding the right type of water may seem a bit of a chore to you, but it extends the life of your humidifier and, more importantly, it makes your sleeping environment cleaner because of the air you breathe , clean and clean is healthy.

With that in mind, you should clean your filters and tank when you change the water in the humidifier, and do it every few days.

Tips: Changing the water frequently will avoid the formation of bacteria in the humidifier, allowing for cleaner air.

If you feel like the dispenser walls are covered with a lot of mold and dust and you are having trouble cleaning it, this may be a signal to replace your entire humidifier.

Conclusion

Humidifiers and heating go hand in hand in the winter months. One keeps you warm and cozy while the other allows you to breathe fresh and cool air while you sleep. Remember that a fresh and cool sleeping environment is paramount to the quality of your sleep and dreams, which directly affects your overall health.

If we put aside the small conditions you need to meet to maintain your humidifier, using a humidifier is easy and safe throughout the night. There are many benefits of using a humidifier throughout the night, such as:

Better sleep quality

Less snoring and symptom reduction in sleep apnea

More moisture for your plants

Moisture for skin, hair and nails.

Relief of cold and flu symptoms

Speedy recovery from an illness

No morning voice

… and much more.

Dry and itchy skin is as much a part of winter as snowstorms and warm blankets. At Gross Heating & Air Conditioning we understand that – that’s why our experts are here to help you make your stay as comfortable as possible. Below we share some telltale signs that you need a humidifier. If you spot any of these clues in your home in the Brookfield area, call us today to help resolve them: 262-783-6000.

What does a humidifier do?

Humidifiers absorb water and emit it as a mist, adding moisture back to the dry air. Cold weather naturally strips this moisture from the environment, causing problems like dry skin, frequent colds, and even cracked wooden furniture. Humidified air — which the Environmental Protection Agency says should be between 30 and 50 percent humidity — eliminates these symptoms of dry air, helping your home feel warmer and increasing your overall comfort.

These systems can even help fight certain airborne viruses — including the coronavirus. According to experts like Dr. Stephanie Taylor, an infection control consultant at Harvard Medical School, says our vulnerability to respiratory infections like COVID-19 increases when humidity drops to 20 percent. Home humidifiers are a great way to fix that. “Humidification has been shown to reduce viral infectivity in a range of settings, including hospitals, day care centers, long-term care facilities, transportation vehicles, and the home,” explains Dr. Taylor.

How to know if you need a humidifier

Here are three signs it’s time to start thinking about a whole-home humidifier:

Dry and itchy skin

Your skin is one of the best indicators that the humidity in your home is low. If it itches and cracks, dry air could be to blame. A humidifier can alleviate these problems better than lotion or lip balm.

constipation and nosebleeds

Also listen to your nose. Low humidity can cause your nasal passages to dry out, which can lead to a stuffy nose — especially in the morning or evening — and sudden nosebleeds. Dry air can also aggravate asthma or other respiratory conditions, making a humidifier a good option for relieving some of these problems.

Too much static electricity

Moisture goes a long way in blocking static electricity and debris. So if the moisture level gets too low, the likelihood of static shock increases. Although this sign is more of a nuisance than a problem, too much static electricity can, in extreme cases, disrupt or destroy your electronics.

Summer is just around the corner, leaving little time for the body to adapt to the sudden temperature changes. While the season unleashes boundless energy for many people, the hot weather can trigger breathing problems for those suffering from respiratory diseases such as chronic obstructive pulmonary disease (COPD) and asthma. High heat and humidity lead to asthma attacks and other respiratory diseases in several cases. Various studies have found the link between hot weather and breathing difficulties.

How hot weather affects breathing

From stagnant air to increased pollution levels, it can become difficult to breathe properly when it’s hot all around. In extreme weather conditions (excessive heat or cold), the body needs more oxygen to maintain internal temperature, which impairs lung function and leads to deep or rapid breathing (hyperpnea). Scientific research has shown various effects of hot weather on breathing, some of which include:

● During the summer season, the pollen count in the air increases. This can trigger respiratory symptoms like coughing, wheezing, and shortness of breath in people with respiratory conditions like asthma, allergic rhinitis, and COPD.

● A study published in the journal Respiratory Physiology & Neurobiology concluded that hot air causes airway irritation and coughing in people suffering from allergic rhinitis (an inflammatory disease of the upper airways). It was believed that the reason for this was the activation of the thermal sensors on the nerves of the larynx (voice box) and upper respiratory tract.

● Another study published in the European Respiratory Journal found that breathing hot air causes inflammation in the airways and also causes the airways to tighten (bronchoconstriction), leading to shortness of breath.

● The Lancet states that at extremely high temperatures, air stagnates and locks in all pollutants (including Particulate Matter 2.5 and ozone) in the air, leading to worsening respiratory symptoms.

● In hot weather, people sweat more and are prone to dehydration. This can dry out the nasal passage, bronchi, and lungs, which can lead to shortness of breath.

● It has also been found that hot air contains more water vapor than cool air, resulting in lower levels of oxygen and higher humidity in the air. This dense air can be difficult to breathe, especially for people with chronic lung problems.

How to care for the lungs in hot weather?

You can take care of your lungs this summer by making a few simple changes to your daily routine. A few examples could be:

1. Stay indoors: Do not leave the house unless necessary. Keep windows and doors closed to keep the house cool.

2. Stay up to date on weather conditions: Before you go out, check the weather (temperature and humidity), pollen counts in the air and the air quality index (AQI). Do not leave home when pollen and particulate matter are high in the air, as they combine with heat and can cause coughing and wheezing, especially in those with respiratory conditions. If you must go out, wear a face mask to prevent inhaling pollutants and pollen.

3. Plan your day accordingly: Avoid going out during the warmest part of the day, usually between 11am and 3pm. Schedule work or activities either in the early morning or in the evening when the air gets a little cooler.

4. Quit Unhealthy Lifestyle Habits: Smokers need to quit smoking to improve their breathing and lung function. Avoid drinking alcohol as it tends to dehydrate the body.

5. Choose the right clothes: In summer, wear loose, light-colored cotton clothes.

6. Don’t overexert yourself: Avoid strenuous exercise such as running, cycling or walking uphill with a heavy backpack.

7. Make the necessary dietary changes: Keep yourself hydrated by drinking plenty of water. Eat foods high in water such as watermelon, musk melon, mango and cucumber.

8. Keep Your Body Cool: Take frequent showers when you feel overheated. Cover up with a shrug, hat or scarf, or use an umbrella when outdoors.

9. Be prepared for a health emergency: Have emergency medication on hand for quick relief (if you have breathing problems).

Bring away

Hot weather and heat waves can affect anyone, but people with pre-existing lung conditions are at an increased risk of side effects and health problems. Therefore, such individuals must keep themselves adequately hydrated by drinking plenty of water and avoiding exposure to hot weather. People suffering from respiratory diseases must contact their doctor if they notice a worsening of their symptoms.

This is a plain English abstract of an original research article

More respiratory infections in adults followed the use of humidified oxygen compared to non-humidified low-flow oxygen therapy. Bacterial contamination was prevalent in the humidified oxygen cylinders in various hospital departments, including respiratory wards.

UK guidelines currently recommend the use of non-humidified oxygen for adults requiring low-flow oxygen. However, in countries like China, oxygen is routinely humidified to prevent dryness of breath, regardless of flow rate.

This review identified 27 studies, most of which were conducted in China. Infection rates were low, less than 2%. There was also no difference in reports of dry nose, throat or chest discomfort.

Adults on long-term low-flow therapy should continue to receive non-humidified oxygen in accordance with UK guidelines.

Why was this study needed?

With long-term oxygen therapy, oxygen is supplied for at least 15 hours per day. It helps maintain blood oxygen levels and reduces feelings of fatigue and shortness of breath in people with chronic obstructive pulmonary disease, as well as other long-term respiratory diseases, heart failure and cancer. Long-term oxygen therapy is often administered at low flow rates, less than five liters per minute, through soft plastic nasal cannulas.

Oxygen can be humidified with the aim of reducing dryness in the upper airways. This may be important in high-flow oxygen therapy, but the benefit of humidifying low-flow oxygen delivered through nasal cannulas has been uncertain. UK national guidelines do not recommend it, but some local guidelines support its use. In some countries, such as China and Japan, oxygen is routinely humidified regardless of flow rate.

This review aimed to clarify the effectiveness of low-flow oxygen humidification.

What did this study achieve?

This systematic review identified randomized controlled trials and quasi-randomized trials comparing humidified and non-humidified low-flow oxygen therapy in hospitalized adults.

A total of 27 studies involving 8,876 adults were pooled in the meta-analysis. Three studies were conducted outside of China. Sterile distilled water was most commonly used as the humidifying fluid (19 of 27 studies) and the oxygen flow rate varied between 1 and 4 L/min.

Objective outcome measurements included bacterial contamination of the humidifier bottle and the time it took medical staff to administer oxygen. Subjective measurements included discomfort in the nose, throat, and chest.

General study limitations included the potential for biased group assignment and patients or staff who were aware of the treatment being administered. Individual study results varied significantly for most endpoints. The magnitude of any demonstrated effect should be treated with caution; however, the direction of action seems plausible given the contamination of humidifier bottles and the association with respiratory infections.

What did it find?

Non-humidified oxygen reduced the likelihood of respiratory infection by almost two-thirds compared to humidified oxygen, with an incidence rate of 1.6% vs. 3.8% (odds ratio [OR] 0.39, 95% confidence interval [CI] 0, 21 to 0.73, four studies).

There was a high rate of bacterial contamination in the humidifier bottles. 34.5% of humidified cylinders were contaminated compared to 12.9% of non-humidified oxygen cylinders (OR 0.16, 95% CI 0.06 to 0.43, eight studies).

There was no significant difference between the groups in terms of frequency of dry nose or throat, nosebleeds, chest discomfort, smell of oxygen, and blood oxygen levels.

What do the current guidelines say on this topic?

The British Thoracic Society’s guidelines indicate that humidification is not required when delivering low-flow oxygen (via mask or cannulas) or high-flow oxygen for short periods. They point out that there is “little scientific evidence” for the benefit of humidified oxygen.

The exception is in patients with a tracheostomy tube, where the air bypasses the nose and throat, where it is normally warmed and humidified. Oxygen humidification is recommended for these individuals.

People who require high-flow oxygen for more than 24 hours, who report dryness or upper airway discomfort, or who have problems with sputum retention may benefit from humidification.

What are the effects?

The results support current guideline recommendations that routine low-flow oxygen humidification provides no benefit and should not be used.

Almost all of the evidence came from studies conducted in China, so population and demographic differences may limit applicability to the UK. For example, in some parts of China, ambient humidity may be a relevant factor to consider. One study found that not humidifying in a dry climate led to more complications.

Due to the low quality of the evidence, a benefit of humidification in certain settings or patient groups cannot be ruled out.

I want to study how temperature affects the concentration of oxygen in the air, since it affects how much oxygen we breathe in per breath. The percentage of oxygen composition in air is 20.95%. However, the oxygen concentration/density in air varies due to the expansion of gas particles and varies inversely with temperature according to P/RT=n/V (where n/V is the density of the gas).

I ran an experiment rusting steel wool to determine the volume percent of oxygen in air (determined by dividing the volume of water lily in a test tube by the total volume of air in the test tube). However, I’m not sure if the % oxygen I determined is a measure of oxygen density (if so, can I convert the percentage to ppm).

My initial hypothesis is that the water level rises less because there are fewer oxygen molecules in hot air since there is less oxygen reacting with the steel wool (compared to cold air). Hence lower percentage oxygen concentration. Vice versa for cold air.

Later I think that oxygen molecules (or gas particles) move faster when heated, so each oxygen molecule occupies more volume. Conversely, when the gas particles are colder. However, since there are more oxygen molecules in cold air than in warm air, the increase in the number of oxygen molecules occupies more volume and offsets the smaller volume each oxygen molecule occupies by moving more slowly.

Therefore, the volume percentage of oxygen in the air I, determined by the volume of the rising water level above the volume of air, is theoretically the same and therefore cannot be used to determine the oxygen density in air.

But then I also saw a picture of a Nonius O2 probe with an O2 percentage reading (which I’m not sure if it’s volume percentage or composition percentage) that can be converted to concentration in ppm with the push of a button. I then did some research and found that percent concentration (by mass or by volume) can be converted to ppm (which is a measure of oxygen density).
