a pressure generating system;
a conduit having a first end operatively coupled to the pressure generating and a second end;
a patient interface operatively coupled to the second end of the conduit;
a sensor operatively coupled to the pressure generating system, the conduit, or the patient interface, wherein the sensor is adapted to detect a parameter indicative of a patient breathing into the patient interface; and
a processor operatively coupled to the sensor and the pressure generating system, wherein the processor determines whether a patient is breathing into the patient interface based on the output of the sensor, wherein the processor is programmed to activate the pressure generating system from a first state, in which the pressure generating system is deactivated, to a second state, in which the pressure generating system is activated and operated in accordance with a pressure support mode over multiple respiratory cycles, responsive a determination that such a patient is breathing into the patient interface.
2. The system of claim 1, wherein the processor is programmed to deactivate the pressure generating system responsive a determination that such a patient is not breathing into the patient interface to cease generation of the pressurized gas by the pressure generating system.
3. The system of claim 1, wherein the pressure generating system comprises:
a pressure generator adapted to generate a flow of gas; and
a pressure controller cooperable with the pressure generator to control the flow of gas within the conduit at variable pressures.
4. The system of claim 1, further comprising pressure ramping means for executing a ramp cycle in which a pressure of the pressurized gas increases over time.
5. The system of claim 4, wherein the ramping means includes a manually actuatable mechanism that, when actuated, causes the ramping means to execute the ramp cycle.
6. The system of claim 1, wherein the pressure support mode includes synchronizing the generation of the pressurized gas with an occurrence of alternating inspiratory and expiratory phases of such a patient’s respiration in a manner to maintain the positive pressure in the patient’s airway during a sequence of the inspiratory and expiratory phases, and wherein the magnitude of pressure during at least a portion of each expiratory phase is less than the magnitude of pressure during at least a portion of the immediately preceding inspiratory phase.
7. The system of claim 1, further comprising an exhaust port defined in at least one of the conduit and the patient interface.
