Abstract
A sound dampening apparatus to be disposed in pneumatic connection with a respiratory support system. The respiratory support system may comprise a source of medical gas, a plurality of pneumatic connections and a patient interface. The sound dampening apparatus comprises an inlet, an outlet, and an outer case which forms a sound dampening chamber. As the medical gas flows through the sound dampening apparatus, the noise energy associated with the flow of medical gas is reduced.
