A breathable gas supply apparatus (30) for a patient features a breathable gas supply system (32) and a respiratory mask assembly (34) in communication with the breathable gas supply system (32). The breathable gas supply system (32) provides a supply of breathable gas to the respiratory mask assembly (34) and removes a supply of exhaled gas from the respiratory mask assembly (32). The breathable gas supply system (32) includes a housing (35) having an inspiration chamber (40) and an exhalation chamber (42) and a movable structure (78) in communication with the inspiration and exhalation chambers (40,42). The movable structure (78) moves in phase with a respiratory cycle of a patient. In one preferred embodiment, the breathable gas supply system (32) includes a second movable structure (98), which moves in response to a phase of the respiratory cycle of the patient. In another one preferred embodiment, the breathable gas supply system (32) is powered to assist the patient's respiratory effort. |
