Abstract
A patient interface comprises a blower, a cushion for contacting a user's face, and a mask body and/or a frame for supporting the cushion on a user's face. The cushion and/or the mask body or frame define an interior space for receiving a flow of gases from the blower. The blower is mounted to the mask body or frame so that the blower is at least partially within the mask body or frame. The blower substantially separates a high pressure side of the mask body or frame from a low pressure side of the mask body or frame and/or the mask body or frame is substantially without a wall between the blower and the interior space.
