Abstract
A pressure support system for delivering a flow of breathing gas to an airway of a patient includes a base unit structured to generate the flow of breathing gas and including a heating control unit, a conduit coupled to the base unit and structured to carry the flow of breathing gas, a thermistor disposed in the conduit, and first and second resistive wires extending along the conduit from the base unit to the thermistor. The heating control unit is structured to selectively operate in a first mode to heat the conduit using the first and second resistive wires and a second mode to sense a temperature of airflow in the conduit with the thermistor via the first and second resistive wires.
