How does CPAP treat obstructive sleep apnea?
Short answer
CPAP treats obstructive sleep apnea by sending gentle, steady air pressure through a mask to keep your airway open during sleep. It does not breathe for you. It can reduce breathing pauses and daytime sleepiness when used as directed. Results vary. A physician selects the device and pressure settings for you.
CPAP stands for continuous positive airway pressure. A small machine sends pressurized room air through a hose and mask. The pressure helps keep your throat from closing while you sleep. CPAP generally uses room air, not added oxygen, unless oxygen is separately prescribed.
CPAP is a common treatment for OSA, especially when it is moderate or severe. Some people use an auto-adjusting pressure device instead. Your physician chooses the type of device and settings based on your sleep test and health needs. Do not change prescribed pressure settings without guidance.
Mask leaks, dry mouth, nasal stuffiness, and skin irritation can make treatment hard to use. A different mask size, heated humidifier, or other adjustments may improve comfort. Results vary. Report ongoing problems rather than giving up on treatment.
Use the device during all sleep, including naps, as directed. Follow the manufacturer's cleaning instructions. Follow-up visits and device data help your clinician check whether treatment is controlling breathing events. Results vary, and repeat testing or adjustments may be needed.
