Abstract

A patient interface includes a frame assembly (16100) including connectors operatively attachable to headgear, a cushion assembly (16175) including a shell (161800) and a seal-forming structure (16200) structured to form a seal with the patient's nose and/or mouth, and an air delivery connector (16600). The cushion assembly and air delivery connector are structured to releasably connect to the frame assembly independently of each other. A static face seal and separate static diametric seal between the shell (161800) and frame (16100). A dynamic face seal and separate dynamic diametric seal between the air delivery connector (16600) and frame (16100). Separate claims (FIG. 6) to a frame assembly (16100) with upper headgear connector arms (16134) including at least one slot (6146) (claim 17) or flexible portions (claim 22) to form hinges structured and arranged to conform to varying facial profiles.
