Abstract
A flow generator includes a blower, a flow generator outlet configured to receive an end of a gas delivery tube, and a controller. The flow generator outlet includes electrical connectors configured to contact corresponding electrical connectors associated with the breathable gas delivery tube when the breathable gas delivery tube is received by the flow generator outlet. The controller includes a tube-type detect circuit and is configured to receive signals from the breathable gas delivery tube by way of the electrical connectors of the flow generator outlet. The tube-type detect circuit is configured so that when the breathable gas delivery tube is received by the flow generator outlet, the tube-type detect circuit determines the type of breathable gas delivery tube based on signals from the electrical connectors of the flow generator outlet that are indicative of a condition of a resistor associated with the breathable gas delivery tube.
