Abstract
A bi-level pressure support system and method of treating disordered breathing that optimizes the pressure delivered to the patient during inspiration and expiration to treat the disordered breathing while minimizing the delivered pressure for patient comfort. The pressure generating system generates a flow of breathing gas at an inspiratory positive airway pressure (IPAP) during inspiration and at an expiratory positive airway pressure (EPAP) during expirations. A controller monitor at least one of the following conditions: (1) snoring, (2) apneas, (3) hypopneas, or (4) a big leak in the pressure support system and adjusts the IPAP and the EPAP based on the occurrence of any one of these conditions.
