ABSTRACT:
A breathing apparatus is provided for the treatment of obstructive sleep apnea that optimizes the positive pressure to the airway of a patient. The apparatus is configured to detect flow limitations in the patient airway from an analysis of inspiratory flow waveforms. The airway pressure setting is raised, lowered or maintained depending on whether a flow limitation has been detected and on the previous actions taken by the apparatus. The apparatus may include a blower, a flow sensor, a pressure sensor, a microprocessor, a pressure controller and a nasal fitting. The apparatus is configured to increase the airway pressure when a flow limitation is detected in the airway of the patient and to decrease the airway pressure when a flow limitation is not detected.
