Abstract
A pressure support system that includes a pressure generating system employing a pressure generator that provides a primary flow of gas to a patient and a supplemental gas system providing a supplemental flow of gas to the patient. A selectively acutable valve associated with the supplemental gas system controls the supplemental flow of gas to the patient, and a control unit coupled to the pressure generating systems controls the valve based on conditions of the pressure generator in the pressure generating system, thereby controlling the flow of the supplemental gas to the patient based on the detected conditions of the pressure generator.
