The distal end of the support portion engages a portion of the body at or about the second end.

Abstract: A cushion is for use in a pressure support system for delivering a flow of breathing gas to an airway of a patient. The cushion includes a body having a first end and a second end located opposite the first end. The body defines a space therein. The cushion further includes a sealing portion defining a single opening into the space. The single opening is adapted to surround both a first nostril and a second nostril of a patient. The sealing portion is located between the first end and the second end. The sealing portion includes a first protruding portion and a second protruding portion each extending outwardly from the body and being adapted to sealingly engage against an interior surface of a corresponding one of the first nostril and the second nostril.

The wear-out indicator (32) includes an elastic structure (34) that appears in a first colour in an unstressed condition and is configured to re-versibly change its apparent colour when being stretched and re-turned to its unstressed condition again. The elastic structure (34) is configured to indicate a wear-out of the member (14, 24, 26) by appearing in a second colour in its unstressed condition when the structure (34) has lost at least a part of its elasticity, wherein the second colour is different from the first colour.
