Abstract:
A pressure support system comprising:(1) a pressure generating system adapted to provide a primary flow of gas to a patient, the pressure generating system comprising:(a) an electrically powered pressure generator adapted to receive a supply of breathing gas from a breathing gas source and to produce the primary flow of gas responsive to power being provided to the pressure generator, and(b) a control unit operatively coupled to the pressure generator for controlling a supply of electrical power to the pressure generator so as to cause the pressure generator to output the primary flow of gas;(2) a supplemental gas system adapted to provide a supplemental flow of gas to such a patient in conjunction with the primary flow of gas; and(3) a selectively actuatable valve associated with the supplemental gas system and with the control unit, wherein the valve substantially disables the supplemental flow of gas responsive to the control unit disabling the supply of electrical power to the pressure generator.
