Abstract

A device for treating a patient suffering from obstructive sleep apnea or snoring can include an expiratory valve connected to a manifold. The expiratory valve can include a body portion including a feedback port configured to be connected to an air flow generator. The expiratory valve can include a plunger at least partially disposed in the body portion. The expiratory valve can include a pressurizing chamber positioned between an end of the plunger and an end of the expiratory valve. The pressurizing chamber can be configured to receive air from the air flow generator through the feedback port.
