A CPAP (continuous positive airway pressure) machine uses mild air pressure to keep a person’s airways open during sleep. It’s used for people who suffer breathing problems like sleep apnea. In fact, according to the National Heart, Lung and Blood Institute, CPAP is the best treatment for people who have obstructive sleep apnea, a common disorder in which a person will pause during breathing or take shallow breaths during sleep, causing insufficient amounts of air to reach the lungs. People must wear a mask that is attached to the machine during sleep, and some of these cover the full face. Sometimes there are problems with the mask that can affect treatment.
Adjusting
It can take a while to adjust to wearing a mask, and some people can have trouble falling asleep. For some, it takes a week or even a month to get used to the CPAP, according to the National Heart, Lung and Blood Institute. Some people do not like the mask because they feel confined. The institute recommends adjusting to the mask slowly if you feel this way. Start by holding the mask to the face for short periods in daytime. Then wear it with the straps for short sessions. Next add the hose. Practice breathing with the machine during the day, and then try it at night for sleep. You also can try a different mask with fewer straps or one that makes less contact with your skin, according to the institute.
Too Loose or Too Tight
A mask that is too tight can lead to sore, irritated, dry or swollen eyes or conjunctivitis, according to the American Sleep Apnea Association. The association recommends a person attempt to reseat the mask on his face, and readjust his headgear straps. Another solution is to use an eye patch. Other signs that a mask is either too tight or too loose are skin irritation, blisters or pressure sores. A person who has a wrong size mask or a worn-out mask is at risk for these problems as well. The association recommends readjusting headgear straps to make the mask as loose as possible while still holding a seal. If needed, consult a respiratory therapist and schedule a mask fitting.
Leaks
Several problems can cause a CPAP mask to leak. You can avoid many of these problems by following the instructions that come with the mask, according to the National Heart, Lung and Blood Institute. For example, wash the mask daily and wash and moisturize your face before bed. Mask straps that are either too loose or tight also can cause a leak. Minute leaks can lead to a shrill sound that will disturb sleep. The institute advises against using tape on a mask in response to a leak unless a sleep specialist or the home equipment recommend doing so.
Mask Removal
People who don’t use the mask all night don’t gain the full benefit of the treatment. Some people remove their masks while asleep, according to the National Heart, Lung and Blood Institute. A person who does this can try several solutions. A mask that fits better may do the trick. A chin strap to hold the mask in place can also be a solution. Getting a CPAP machine with a humidifier can make the treatment more comfortable, and thus halt the urge to remove the mask. A person also can get a CPAP machine that sounds an alarm when the mask comes off.
Allergies or Irritation
Some people suffer mask allergies or other types of skin irritation. The National Heart, Lung and Blood Institute recommends trying a different type of mask or a mask made with a different material if this occurs. Some masks have fewer straps or make less contact with the face.
Operator Error
Use and maintenance issues can cause problems with a CPAP mask. The National Heart, Lung and Blood Institute states the CPAP needs to be used every time a person sleeps—even during naps. Also, the CPAP needs to be used for 7.5 hours minimum each night.
