The apparatus further includes a lid coupled to the housing that is movable between a first position wherein the lid covers the top opening and a second position wherein the lid does not cover the top opening. The apparatus also includes a passage which extends from a first end positioned and structured to receive the flow of breathing gas from the gas flow generator to an opposite second end positioned on the lid and structured to expel the flow of breathing gas into the chamber. An outlet for conveying the flow of breathing gas from the chamber out of the housing is positioned on the housing.
