Claim 4:
5. 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;
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 pressure regulator; and

a first tube comprising a first end and a second end opposite said first end, said first end configured to be connected to said outlet of said gas source device;
a user interface device for providing said gas to a subject;
a second tube having a first end and a second end opposite said first end of the second tube, said first end of the second tube configured to be connected to said user interface device; and
a handheld remote delivery device comprising:
an inlet configured to be connected to said second end of said first tube to facilitate fluid communication with said outlet of said gas source device;
an outlet configured to be connected to said second end of said second tube to facilitate fluid communication with said user interface device;
a flow control device comprising at least one valve for controlling gas flow through the handheld remote delivery device;
a power supply;
one or more user input devices configured to receive an instruction to change the handheld remote delivery device from a first flow setting to a second flow setting;
a remote delivery device controller, wherein, in response to receiving said instruction from said one or more user input devices, said remote delivery device controller is configured to:
cause said at least one valve of said flow control device to move from a first position associated with said first flow setting to a second position associated with said second flow setting; and

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