Abstract
Improved methodology and apparatus for the treatment of sleep apnea through (1) application of alternating high and low level positive airway pressure within the airway of the patient with the high and low airway pressure being coordinated with the spontaneous respiration of the patient, (2) usage of adjustably programmable pressure ramp circuitry capable of producing multiple pressure ramp cycles of predetermined duration and pattern whereby the ramp cycles may be customized to accommodate the specific needs of an individual sleep apnea patient so as to ease the patient's transition from wakefulness to sleep, and (3) remote control operation of the apparatus for assisting those patients whose mobility or capacity for physical exertion is intrinsically limited.
