摘要

Methods and apparatus for controlling air supplied under pressure to a patient suffering from sleep disorders such as apnoea. Controlled pressurized air is supplied to the patient's upper anatomical airways by the apparatus according to the methods of the present invention. The apparatus measures the air flow and pressure to the airway, and determines whether to increase or decrease the pressure based on a determination of several factors, such as the occurrence of an obstructive or central apnoea, hyperventilation, air leakage and acoustical vibrations. Occurrences of apnoeas may be stored by the apparatus and read by a clinician at a later date.
