METHODS AND APPARATUS FOR CONTROLLING MASK LEAK IN CPAP TREATMENT

摘要

A method of operating a device for treating sleep disordered breathing (SDB), wherein the device provides continuous positive airway pressure during sleep, includes determining whether treatment pressure at the patient interface is below a desired value (301), in response to the determining, increasing pressure generated by the flow generator (302), in response to the increasing, making a determination that the increase in flow generator pressure has resulted in less than a desired increase in treatment pressure at the patient interface (303), and in response to the determination, reducing or inhibiting further increase of the flow generator pressure (304, 306).
