Abstract
The system includes an air flow generator configured to deliver an air flow at a positive therapeutic pressure during the treatment, and an expiratory valve with an open pressure connected to the air flow generator. The open pressure is dependent on the therapeutic pressure from the air flow generator. The expiratory valve further exerts a back pressure upon each exhalation from the patient sufficient to create a pneumatic splint in the patient's respiratory tract. The exhalation from the patient has a first half followed by a second half, and the back pressure is varied such that during the start of the first half, the back pressure is between 0 and 50% of a peak back pressure, and increases to a peak back pressure in the second half.
