Side Effects of Using a BiPAP Machine

Sleep apnea obstructs airway flow and impairs your ability to get restorative sleep, according to the American Sleep Apnea Association. Untreated sleep apnea can lead to headaches, high blood pressure and mental impairment that can impact everything from driving to doing your job. A Bilevel Positive Airway Pressure Machine (BiPap) provides pressurized air during the night using a mask, and monitors breathing via an electronic circuit. The most common side effects of using a BiPap are treatable and mild.

Skin Irritations

A BiPap mask that does not fit well can cause a lot of discomfort and even lead to feelings of numbness or skin irritation, according to the Society of Critical Care Medicine's website The website emphasizes the importance of working with your doctor to ensure your mask fits tightly yet comfortably. Although rare, an ill-fitting mask can lead to skin sores at pressure points where the mask makes contact with your skin.


Visible bloating in the stomach that results from swallowing excess air through the BiPap is another complication that can arise, although the website states it is not very common. The website indicates that stomach aches, nausea and even vomiting are possible when gastric bloating happens. recommends changing your sleep position to help remedy this problem. Try removing your pillow, shifting to the side or to your back or elevating your head. If changing your position doesn't work, your doctor can work with you to adjust the machine's pressure levels.


Many complain about side effects associated with breathing extremely dry air night after night using the BiPap machine. Dried, chapped lips and even nosebleeds can result. While lip balm will help remedy the chapped lips, using a humidifier or purchasing a BiPap machine with a built-in humidifier appears to alleviate the dryness of the nasal passages that leads to nosebleeds. The website of Sleep Medicine Associates also recommends using nasal saline spray to keep the nostrils and nasal passages moist.
