Abstract: A respiratory therapy device is configured, e.g. by a care provider, such that a second therapy mode different from the current therapy mode is unlocked, under predetermined circumstances and a third therapy mode different from the current and the second therapy mode is unlocked, under predetermined circumstances. The user of a given respiratory therapy device may activate the unlocked second or third therapy mode. The second or the third therapy mode may expire after a predetermined amount of usage, and be deactivated.

Abstract: A method of automatically controlling the temperature of a patient circuit (56, 58) of a pressure support system (50) includes determining (directly measuring or estimating/deriving) one or more environmental parameters relating to environmental conditions around the pressure support system, such as ambient temperature and/or ambient humidity, determining a desired temperature based on at least the one or more environmental parameters, and controlling the operation of a heating apparatus (70) operatively associated with the patient circuit based on the desired temperature. Also, a pressure support system implementing the method.

Abstract: Passive heating may be provided to a flexible tube (202) configured to deliver respiratory gas to a patient. A flexible sheathing body (206, 208, 210) may be removably attached to the flexible tube so as to surround the flexible tube and extend along the flexible tube. A passive heating element (218, 220, 222) integrated with the flexible sheathing body may store non-electrical energy and release the stored non-electrical energy as thermal energy to heat the flexible tube.

Abstract: A humidifier for use with a pressure support system. The humidifier includes a body having an inlet, a fluid holding chamber, and an outlet. The inlet is positioned upstream and in fluid communication with the fluid holding chamber. The outlet is positioned downstream of and in fluid communication with the fluid holding chamber. A back-flow preventing valve is positioned upstream of the fluid chamber. The back-flow preventing valve is movable between an open position, in which the inlet is unblocked, and a closed position in which the inlet is blocked. In the closed position, the back-flow preventing valve prevents fluid, fluid vapor, or both from entering the pressure support via the inlet to the humidifier.

Abstract: A tool for use in conjunction with a pressure support system that is structured to provide therapy to a patient to treat a condition of the patient by delivering a flow of breathing gas to the patient. The tool may be implemented on a portable electronic device or a PC and is configured to, among other things, provide customized/personalized education and feedback to the patient based, at least in part, on data that is measured by the pressure support system during the provision of therapy to the patient. The tool utilizes certain patient/therapy metrics, wherein each patient/therapy metric comprises raw data that was measured by the pressure support system and that has been processed (e.g., summarized and/or otherwise manipulated) to form the patient/therapy metric.
