What is CPAP?

OSA is most commonly treated with CPAP, which stands for continuous positive airway pressure. Treatment with CPAP involves a mask placed over the nose, or both the nose and mouth during sleep.

The mask is attached via a hose to the CPAP machine, which takes normal air from the room and uses it to gently push open the airways so that it can flow freely into your lungs.

The treatment is painless and allows an uninterrupted airflow during sleep. When CPAP is used correctly and OSA is treated, oxygen levels are maintained and sleep quality improves.
