Continuous positive airway pressure therapy (CPAP uses a machine to help a person who has obstructive sleep apnea (OSA) breathe more easily during sleep. A CPAP machine increases air pressure in your throat so that your airway doesn't collapse when you breathe in. When you use CPAP, your bed partner may sleep better too.
You use CPAP at home every night while you sleep. The CPAP machine will have one of the following:
- A mask that covers your nose and mouth.
- A mask that covers your nose only—called nasal continuous positive airway pressure, or NCPAP (this type of mask is most common).
- Prongs that fit into your nose.
