How does CPAP work?
A typical CPAP unit has two parts: a sealed mask that fits snugly over your nose (and, in some cases, your mouth as well), and a fan that blows air through the mask into your nose. Sleep apnea is caused by blockage of the airway. The constant flow of air from the fan helps keep your airway open so you breathe normally throughout the night. Your doctor will recommend an airflow level to start with, based on information collected during your sleep study. It may take a couple of weeks of adjustment to find the air pressure that’s right for you. CPAP pros and cons The CPAP sensation may take some getting used to at first.
