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.

Humidifier with back-flow prevention valve

A patient treatment system and method comprising a patient circuit, a pressurizing flow module disposed in the patient circuit, a humidifier disposed in the patient circuit, a monitor, sensors within the patient circuit, and a processor. The patient circuit delivers a flow of gas from a gas source to an airway of a patient. The pressurizing flow module elevates the pressure of the gas within the patient circuit. The humidifier elevates the humidity of the gas in the patient circuit to a circuit humidity level. The monitor monitors at least one parameter of the gas from the gas source. The sensors generate corresponding signals that can be processed to estimate a rate at which vapor is added to the gas in the patient circuit. The processor determines the humidity level of the gas in the patient circuit downstream from the humidifier based on the signals generated by the sensors and the at least one parameter of the gas in the gas source.

System and method for determining humidity in a respiratory treatment system

A patient treatment system that comprises a gas delivery system, a patient interface, and a control interface to provide a pressurized flow of breathable gas. The patient interface is in communication with the gas delivery system, and is constructed to interface with a patient to provide the breathable gas to the patient. The control interface is carried by the patient interface, and enables the patient to control at least one aspect of the patient treatment system.

Patient treatment system with a patient interface mounted control

A method of employing a pressure generating system that provides a pressure therapy to the pulmonary system of a patient and to enable the patient to interact with the pressure support system, for example, to monitor the effectiveness of the treatment provided by the pressure support system. The interactive system includes an output device that provides first information to the patient, an input device that allows the patient to provide second information that is based on the first information and a control unit that controls the operation of the output device to present the first information and collection of the second information via the input device. In a further embodiment, the operation of the pressure generating system is controlled based on the second information provided by the patient.

Method of providing interactive pressure support

An interactive pressure support system and method employing a pressure generating system that provides a pressure therapy to the pulmonary system of a patient and an interactive system associated with the pressure generating system to enable the patient to interact with the pressure support system, for example, to monitor the effectiveness of the treatment provided by the pressure support system. The interactive system includes an output device that provides first information to the patient, an input device that allows the patient to provide second information that is based on the first information and a control unit that controls the operation of the output device to present the first information and collection of the second information via the input device. In a further embodiment, the operation of the pressure generating system is controlled based on the second information provided by the patient.
