Abstract

A patient interface device (8) includes a patient sealing assembly (12) adapted to communicate a flow of breathing gas within an airway of a patient, the patient sealing assembly including a cushion (14), a frame member (16) coupled to the cushion, and an adjustable forehead support assembly (26) coupled to the frame member. The adjustable forehead support assembly includes a forehead cushion (30) and an inflatable and deflatable bladder (48) coupled to the forehead cushion, wherein inflation and deflation of the bladder causes the distal end (24) of the frame member to move relative to the forehead cushion in a manner wherein a pressure applied to a bridge of a nose of the patient by the cushion is adjusted.
