Continuous positive airway pressure (CPAP) therapy is a common treatment for obstructive sleep apnea. A CPAP machine uses a hose connected to a mask or nosepiece to deliver constant and steady air pressure to help you breathe while you sleep.
A CPAP machine takes in room air, then filters and pressurizes it before delivering it through a tube and into your mask. The continuous flow of air gently keeps your tongue, uvula and soft palate from shifting too far into your airway. This stabilizes your breathing and improves your overall sleep quality.
CPAP to treat sleep-related breathing disorders including sleep apnea, CPAP also may treat preterm infants who have underdeveloped lungs.
