Claim 14:
15. A system for providing therapy gases to a subject, the system comprising:
a gas source device comprising:
an inlet configured to receive gas from a gas source;
an outlet;
a pressure sensor configured to generate one or more signals responsive to detecting pressure of gas at said outlet;
a flow sensor configured to generate one or more signals responsive to detecting flow volume of gas passing through said gas source device; and
a gas source device controller configured to receive said one or more signals generated by each of said pressure sensor and said flow sensor; and

a remote delivery device comprising:
an inlet configured to be connected to said outlet of said gas source device via a first tube;
an outlet configured to be connected to a user interface device via a second tube, said user interface device configured to provide said gas to a subject; and
a flow control device for controlling gas flow through the remote delivery device;
one or more user input devices configured to receive an instruction to change the remote delivery device from a first flow setting to a second flow setting;
a remote delivery device controller configured to control operation of said flow control device based on said instruction to change said remote delivery device from said first flow setting to said second flow setting;

wherein the gas source device controller is configured to:
determine said change in the remote delivery device from said first flow setting to said second flow setting based on at least one of said one or more signals received from said pressure sensor and said one or more signals received from said flow sensor; and
alter at least one of pressure and flow volume of gas flowing through said outlet of said gas source device to said remote delivery device based on said determined change in the remote delivery device from said first flow setting to said second flow setting.
