Abstract
A cushion for a patient interface includes two or more bladders arranged in concentric relation. Each of the bladders includes a face-contacting portion adapted to engage the patient's face, and each of the bladders is adapted to be pressurized independently from one another. At least one of the bladders is an active bladder that is pressurized to at least a sealing pressure to form a continuous seal with the patient's face in use.
