Abstract:
1. A method for adjusting a desired pressure in a positive airway pressure device, the method comprising: a) providing a breathing gas under positive pressure to a patient via a positive airway pressure device based at least in part on a current desired pressure; b) monitoring a characteristic of the breathing gas that is indicative of respiration; c) creating a breathing cycle signal with a first level associated with inhalation and a second level different from the first level and associated with exhalation, the breathing cycle signal being based at least in part on the monitored respiration characteristic; d) performing one or more abnormal breathing checks based at least in part on the monitored respiration characteristic and the breathing cycle signal, wherein one or more abnormal breathing checks comprises a hypopnea check, the hypopnea check comprising: e) if abnormal breathing is detected, increasing the current desired pressure by a first increment until a maximum desired pressure is reached, otherwise, decreasing the current desired pressure by a second increment until a minimum desired pressure is reached.
