What Is a CPAP Nasal Mask?
A CPAP nasal mask is a device, used in the treatment of obstructive sleep apnea, which aims to prevent the closure of the wearer’s airways by increasing the air pressure in the nose and throat. Obstructive sleep apnea is a condition in which the sufferer experiences pauses, caused by obstruction of the airways, in his or her breathing during sleep. These pauses last long enough to cause the sleeper to miss one or more breaths of air, and occur repeatedly during the night, usually resulting in significant daytime drowsiness.
