Claim 0:
1. A ventilation system for delivering respiratory therapy to a patient, the ventilation system comprising:
a patient interface device for delivering pressurized respiratory gas to a patient;
a connector system for connection to a source of pressurized respiratory gas, the connector system comprising a hollow body having a cavity therein;
a conduit system fluidly connecting the connector system to the patient interface device, wherein the conduit system includes a first gas line and a second gas line, and the second gas line is positioned within the first gas line for a length of the second gas line which extends between the patient interface device and the connector system;
a first valve forming a pressure relief valve configured to control a maximum pressure of the respiratory gas in the system; and
a plurality of closable ports that allow a plurality of different modes of respiratory therapy to be provided, the plurality of closable ports comprising:
a first closable port in the hollow body for connection to the source of pressurized respiratory gas; and
a second closable port forming an exhaust port closable manually or via a second valve;

wherein, in a first mode, the second gas line provides respiratory gas to the patient interface device and the first gas line provides an exhaust channel to remove exhaled gases from the ventilation system by venting exhaled gas through the exhaust port and, in a second mode, respiratory gas is supplied via the first closable port such that the first gas line provides respiratory gas to the patient interface device and the exhaust port is closed manually or via the second valve such that respiratory gas is directed to the patient at the maximum pressure.
