How Do CPAP Machines Work?

A continuous positive airway pressure (or CPAP) machine is used to treat people with sleep apnea disorder. CPAP is often used to treat Obstructive Sleep Apnea which can cause interruptions in your breathing. This happens when your airways briefly collapse, or something temporarily blocks them. When patients use a CPAP machine, a steady flow of pressurized air flows into their nose and mouth as they sleep. This keeps your airways open and allows you to breathe without trouble.
