Obstructive Sleep Apnea or OSA is a serious sleep disorder that results when the throat completely or partially closes which causes disordered breathing. You then snore or choke to intake air, which interrupts your sleep. While there are several treatment paths recommended for those who suffer from OSA, the most common approach is to use a CPAP machine which provides continuous positive airway pressure (CPAP).
The purpose of a CPAP machine is to keep your airway open. The machine filters air through a mask that funnels a constant stream of air into your airway. This constant stream of air creates enough pressure to maintain open airway and maintain proper oxygen levels. You can then sleep without waking up, choking or snoring.
