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.

Auto-feedback valve for a sleep apnea device

A nasal pillow system for treating sleep apnea is disclosed that may include a nasal pillow. The pillow has a cavity wall that defines a cavity, and two nasal interface structures connected to and extending away from the cavity wall. The nasal interface structures are in fluid communication with the cavity. Each nasal interface structure includes a conical nasal interface, a cylindrical trunk structure connected to conical nasal interface, and an annular relief pocket connected to the cylindrical trunk structure and to the cavity wall. The connection between the annular relief pocket and the cavity wall defines substantially a plane, and a first portion of the annular relief pocket extends away from the plane while a second portion extends towards the plane.

Apparatus, systems, and methods for improved treatment of obstructive sleep apnea

Apparatus, systems, and methods are provided for treating obstructive sleep apnea. A CPAP system with an integrated oximeter sensor is disclosed wherein the sensor communicates with an oximeter processor that controls the blower. A nasal air flow sensor may also be incorporated that provides more data to the processor. A unique lightweight, flexible and stretchable hose for CPAP systems is also disclosed. The hose may have a magnetic connection with the blower.

Apparatus, systems, and methods for treating obstructive sleep apnea

Apparatus, systems, and methods are provided for treating obstructive sleep apnea. A unitary valve assembly removably located inside the exterior profile of a nasal pillow mask uses positive airway pressure from a low-flow hose to automatically create an on-demand therapeutic air splint in the pharynx. During inspiration the mask's valving system allows room air to be inspired. During exhalation another valve governs therapeutic backpressure equal to the prescribed pressure setting of the CPAP blower machine. The mask may be worn when the CPAP blower machine is off, and systems are provided for turning the CPAP blower machine on only when needed.
