Abstract

A patient interface assembly includes a cushion and frame assembly with a cushion portion and a frame portion that together form a breathing chamber. The frame portion includes an anterior aperture configured to receive the flow of breathable gas. Headgear includes a back portion, a pair of upper headgear straps extending from the back portion, and a pair of lower headgear straps. The patient interface assembly also includes a shroud in the form of a contoured plate. The shroud is removably mounted on the frame portion by way of a snap-fit connection and includes a pair of lower headgear connectors. The patient interface assembly also includes a forehead support extending from the shroud and having a free end with an upper headgear connector. The forehead support has a first curvature that curves in a first direction around an axis that is offset from the patient interface assembly and extends along a length of the forehead support.
