CPAP (Continuous Positive Airway Pressure; pronounced see-PAP) therapy is the most common treatment for sleep apnea and is the first treatment most doctors recommend.
CPAP is a simple mechanical aid, which helps to keep your airway open at night when you sleep. CPAP prevents your airway from closing through the application of air pressure. Pressure is created by air blowing through the nose, or nose and mouth, into the upper airway. This gentle pressure, applied continuously throughout the night, allows for normal breathing and for you to get the deep sleep you require for restful and restorative sleep.
