Abstract
Systems and methods for adjusting a desired pressure in a positive airway pressure (PAP) device are provided. In one embodiment, the method includes: a) providing breathing gas under positive pressure to a patient via a PAP device based on current desired pressure, b) monitoring a characteristic of the breathing gas, patient, or PAP device indicative of respiration, c) creating a breathing cycle signal having a first level associated with inhalation and a second level associated with exhalation, the signal being based on the monitored respiration characteristic, d) performing an abnormal breathing check based on the monitored respiration characteristic and the breathing cycle signal, and e) if abnormal breathing is detected, increasing the current desired pressure until a maximum desired pressure is reached, otherwise, decreasing the current desired pressure until a minimum desired pressure is reached. Several embodiments of an apparatus associated with the method are also provided.
