Abstract

A mask includes a shroud; a cushion module that engages the shroud, the cushion module including a frame and a full-face cushion adapted to engage the patient's face generally along nasal bridge, cheek, and chin regions of the patient's face, the frame at least partly defining a breathing chamber; an elbow connected to the frame in a releasable and rotatable manner, the elbow being adapted to be connected to an air delivery tube to deliver breathable gas to the patient; and headgear removably attachable to the shroud, wherein: the frame includes an opening, the elbow including a distal end releasably inserted into the opening of the frame with a snap-fit, thereby connecting the elbow to the frame, whereby the connection between the elbow and the frame also maintains the shroud in engagement with the frame.
