Start the setting at "3" and adjust for comfort. If your symptoms are not resolved, you may need to turn it up to a higher setting. Continue in this manner until your symptoms are resolved. If you start to experience moisture in the mask tube, you need to turn it down, heat the room, or use a tubing Wrap.
The amount of water needed varies from one humidifier to the next, from one patient to the next, and with the temperature and humidity of the bedroom.
The water should be changed for each use - even if don't use it all in one night.
If you mean "why does it vary from one night to the next?" it may be that you are mouth breathing or have mouth leak. If you mouth breath, you let lots of air escape from your mouth. All the extra air that escapes uses up your water more quickly.
This condensation is called "rainout". If your room is cold, the warmed, humidified air hits the colder room temperature and cools. When air cools, the amount of humidity (water vapor) that it can hold is reduced, which causes the humidity to "rain out". The amount of water air can carry varies with temperature: warmer air can carry more water while cold air can carry less. As warm air becomes cooler (eg, overnight), it has less capacity to carry water, so water condenses and forms droplets.
There are several ways to deal with this situation.
Up to 40% of PAP users experience nasal congestion and dryness of the nose and throat. These symptoms can be severe enough to prevent patients from continuing their treatment. The humidifier adds moisture and warmth to the air delivered by a CPAP or bilevel system. This reduces symptoms of dryness and congestion, improving patient comfort and compliance. Research also shows that nasal resistance can promote mouth breathing, which in turn leads to additional dryness. Heated humidification can prevent the large increase in nasal resistance that results in mouth breathing and leaks.
A full face mask should not change the amount of water used each night. If you had a mouth leak before, you could have been losing lots of air and humidity through your mouth, in which case you should use less water now.
No. The tubing supplied with CPAP machines can withstand far higher temperatures than the heat generated by the humidifier.
If you find the air dry and irritating, then you may want to turn your humidifier on 20 minutes prior to going to bed.
Humidification doesn't help with OSA or UARS, it does help with side effects caused by CPAP. If you are already on CPAP treatment and experiencing nasal dryness/symptoms, then humidification should help decrease the symptoms. The nasal symptoms are due to the increased flow of air through the nasal passages. Humidification adds moisture to the air breathed and helps the nasal passages cope with the increased flow of air.
Using distilled water will maximize the life of the water tub and reduce mineral deposits. However, it is ok to occasionally use tap water to clean your humidifier. Do not use: bleach, alcohol, chlorine or ammonia-based solutions; moisturizing, antibacterial or glycerine based soaps; and water softening and unapproved descaling agents.

When PAP treatment is needed in-flight, please contact the airline at least two weeks prior to traveling to allow airline reservations personnel to obtain approval from the airline's Medical Services department and check whether any special requirements or restrictions apply.
Follow these recommended preparations:
No. The x-ray scanners will not harm your CPAP device. However, Security may require you to show the medical statement from your physician verifying that you are carrying medical equipment. Make sure this is handy.
Yes. If you are having surgery, it is very important that you tell both the surgeon and the anesthesiologist that you are being treated with CPAP. You should also inform the attending physician that you have been diagnosed with obstructive sleep apnea (OSA).
Facial muscles change when we lie down and further relax once we are asleep, so it is always best to fit the mask while you are in your sleeping position. If you sleep in a bed with no pillows, fit your mask like that. If you sleep in a recliner, fit your mask that way.
This type of problem is likely occurring due to nasal congestion. If you have a history of sinus and allergy problems, you may be better treated with a full face mask and/or humidification. You should discuss this with your primary care physician.
It probably means you have an incorrectly fitted mask. When using a ResMed mask, it is important not to over-tighten the mask system. If you can only get a good seal by over-tightening the headgear, you probably have the wrong size cushion or an incorrectly adjusted forehead support. If you are using a ResMed mask that has a MicroFit dial, it is important to note that your clinician has set the dial at the optimal position and adjusting it significantly from that position may cause discomfort.
Yes, full face masks have a special anti-asphyxia valve that opens if your PAP device loses power. This feature allows you to breathe room air in the event of a power failure.
This may indicate one of several things:
You should replace your mask cushion periodically because as it becomes worn, it becomes less effective. The life of a mask cushion depends on use, the oils from your skin, and cleaning. It is always a good idea to inspect your mask routinely; poor care may adversely affect the fit of the cushion and thus performance.
To get the longest life from your mask, be sure to wash your face each night before putting on your mask, and wash your mask after each use. Use only mild soap, nothing with perfumes, moisturizers, antibacterial agents, bleaches, etc, Always dry your mask and cushion out of direct sunlight. Poor performance is often the first clue that your cushion may need replacement. Check for small tears or pinholes, anything that might cause a leak. Household pets have been known to damage cushions by playing with them and so have children, so you may want to keep your mask out of reach. Also, be sure you don't leave your mask somewhere that receives direct sunlight during the day.Back to question list
You will need to replace your headgear occasionally. Like mask cushions, the life of headgear depends on use, the oils from your skin, and care (cleaning, etc). Taking good care of your mask is the key to maintaining the best performance and mask fit. Wash your headgear at least once per week and dry it out of direct sunlight. If you have oily skin or hair, you may need to wash it more often. Headgear should last longer than a mask cushion, but it will depend on use and environment.
If you mouth breathe or have mouth leaks, then a full face mask will provide a number of benefits over a nasal mask. A full face mask will stop air loss that can compromise treatment, and it can resolve dry throat and nose problems. If you mouth breathe or have leaks, you will not be receiving your full treatment pressure and thus may not be getting the full benefits of your treatment.
Even if you don't mouth breathe, you may still experience mouth leaks. Mouth leaks can contribute to decreased treatment effectiveness and consequent symptoms of poor therapy.
With a deviated septum, you are likely breathing through your mouth due to your nasal passage being blocked. A full face mask will certainly work for you and would allow you the option of breathing through you nose and/or mouth. If your mouth is dry in the morning, you are probably breathing through your mouth.
Yes, however the thing to remember is that every mask has slightly different flow characteristics, so if you're using an Auto or BiLevel device, you'll need to change the mask setting on the user menu when you switch masks.
Everyone is different. Some people find that they prefer a full face mask while others prefer a nasal mask. It is really personal preference. However, both our nasal and full face masks utilize the same cushion technology that inflates to form a floating seal, maximizing patient comfort.
Depending on the flexibility of the cushion, most masks will seal on a moustache, more flexible = better. A shallow cushion in particular is ideal for patients with a moustache, as they may need to adjust the cushion in closer to the top lip. A shallow cushion allows the user to angle the cushion more and maintain the seal at the bridge of the nose.
Yes. Based on one recent study, one could argue that people using bilevel therapy are more likely to benefit from a full face mask because they are more prone to mouth leak and mouth breathing. In the study, data showed that nearly ALL patients on non-invasive positive pressure ventilation (NPPV) experienced some degree of mouth leak and/or mouth breathing. Mouth leak reduces the quality of your sleep and causes sleep fragmentation.
Yes. Switching to a full face mask may eliminate or reduce your need for humidification.
Constant air flow, especially at high treatment pressures, can lead to dryness, nasal irritation and nosebleeds. Humidifiers provide relief from nasal irritation and dryness by adding warmth and moisture to the air delivered by the CPAP or bilevel system. There are also nasal oil products available in most pharmacies to help treat and prevent dryness.
