Zusammenfassung:	A system for providing respiratory therapy includes a nebulizer (300) operable to aerosolize a medicament, a cylindrical mixing chamber (100), an impacting cap (200) and a recirculation tube (500). The mixing chamber has an inlet port, an outlet port, an aerosol port in fluid communication with the nebulizer, and a drainage port. The inlet port receives a flow of breathing gas. The mixing chamber receives the aerosol via the aerosol port, entrains aerosol into the flow of breathing gas, and delivers the breathing gas entrained with aerosol to the outlet port. The impacting cap receives and coalesces a portion of the aerosol into droplets within the space defined by the mixing chamber and the impacting cap. The mixing chamber is also configured to direct rain-out resulting from the droplets to the drainage port. The system also includes a recirculation tube to return the rain-out to the nebulizer.
