How Does CPAP Therapy Work?

CPAP therapy works by delivering a continuous flow of air through a mask that covers the nose or both the nose and mouth. This flow of air helps to keep the airway open during sleep, preventing it from collapsing and disrupting breathing. The air pressure delivered by the CPAP machine is set to match the individual needs of the patient and is generally adjusted to a level that is just enough to keep the airway open, but not so high as to be uncomfortable.

The CPAP machine is equipped with a motor that generates the air pressure, a hose that connects the mask to the machine, and a filter that cleans the air. The patient wears the mask over the nose or both the nose and mouth during sleep, and the air pressure is adjusted as needed to maintain an open airway.

By delivering a constant flow of air to the airway, CPAP therapy helps to reduce or eliminate the symptoms of sleep apnea, such as snoring, restless tossing and turning during sleep, and excessive daytime sleepiness. It can also improve other health issues related to sleep apnea, such as high blood pressure, heart disease, and depression.
