The delivery tube has an inside diameter of about 15 mm or less. The apparatus also including a control system configured to provide a control signal to the blower for controlling a pressure of the supply of breathing gas to between about 1 cm H2O to about 6 cm H2O at the user breathing interface. The control signal is based upon, at least in part, one of a pressure and a flow rate of the supply of breathing gas at the user breathing interface.
