Abstract

A cushion for use with patient therapy may include a face contacting element having at least one portion including at least a first gel and a skin portion containing the first gel. The skin portion may be silicone based. The face contacting element may be substantially triangular, and at least one of the cheek regions and the lower region of the triangular face contacting element may include a concave section that curves inwardly towards the breathing chamber. The cushion may include first and second gels having one or more properties that are different from one another.

Claims
