Positive pressure - Wikipedia

Positive pressure is a pressure within a system that is greater than the environment that surrounds that system. Consequently, if there is any leak from the positively pressured system it will egress into the surrounding environment. Use is also made of positive pressure to ensure there is no ingress of the environment into a supposed closed system.

Positive Airway Pressure Therapy for Sleep Apnea – Sleep Apnea

Positive airway pressure, or PAP, is the most effective and most widely used method for treating obstructive sleep apnea, particularly in its severe form—25 or more apneas and hypopneas per hour. A PAP machine works by gently blowing pressurized room air through the airway at a pressure high enough to keep the throat open.
