sleep apnea
n.
A temporary suspension of breathing occurring repeatedly during sleep that often affects overweight people or those having an obstruction in the breathing tract, an abnormally small throat opening, or a neurological disorder.

This is the common CPAP mask. This is the most common remedy for Sleep Apnea. It is a device used for "Continuous Positive Airway Pressure"(CPAP). Continuously holding the airway open so you are able to breath independantly. This apparatus will not initiate artificial respiration for the subject, yet it is enough positive pressure to support the airway. Every patient is different and will need to sleep on a prescribed pressure measured in cm H2O. This way you are able to recieve a very healthy, natural night of sleep.
