Abstract

An elbow for a mask system includes a proximal end adapted to be provided to the mask system, a distal end adapted to be provided to an air delivery conduit, and a baffle provided within the proximal end. The baffle has a generally planar configuration that defines an intake port that directs incoming air from the air delivery conduit into a mask cavity and an exhaust port separated from the intake port that directs exhaust air from the mask cavity to atmosphere. The baffle includes an end portion that is adapted to extend into the mask cavity defined by the mask system.
