Abstract
A method and apparatus provides multi-level positive air pressure to the airway of a patient for breathing by the patient. An air flow generator is connected to a plurality of valves and hoses connected to and adapted to control and direct the flow of air from the air flow generator. A mask is connected to the air flow generator by the hoses, the mask adapted to deliver air to the airway of a patient. The plurality of valves deliver multiple, different levels of positive airway pressure to the airway of a patient. Alternatively, the air flow generator may include a plurality of blower apparatuses connected to the corresponding plurality of valves and hoses.
