What does a CPAP machine do?

ANSWER

These machines use a mask that fits over your nose, or nose and mouth. It blows air at a pressure that keeps your airway open during sleep.

Over the years, these devices have become smaller, lighter, and much quieter.

Some common side effects include nasal congestion, dry mouth, and skin irritation -- but treatments can help relieve all of them.
