What Is The Difference Between CPAP and BiPAP Machines?
CPAP and BiPAP machines both treat sleep apnea by delivering pressurized air through a mask, but they function in different ways and are suited to different needs. A CPAP machine provides a continuous, single level of pressure to keep the airway open, making it the standard treatment for obstructive sleep apnea. In contrast, a BiPAP machine delivers two pressure levels—higher during inhalation and lower during exhalation—which can make breathing more comfortable for people who have complex sleep apnea, respiratory disorders, or difficulty exhaling against constant pressure. The best option depends on the person’s specific condition and comfort.
