Abstract

A pressure support methodology and system that utilizes at least two, and possibly all three, of information relating to (i) airway patency, i.e., the degree to which the patient's airway is open, (ii) the primary cause of the current sleep disordered breathing event, and (iii) the patient's response to previous pressure changes to automatically titrate pressure when presented with a sleep disordered breathing event. In another embodiment, pressure may be automatically titrated based solely on the primary cause of the sleep disordered breathing event.
