Therapy gas delivery systems (100) that provide run-time-to-empty information to a user of the system and methods for administering therapeutic gas to a patient. The therapeutic gas delivery system (100) may include a gas pressure sensor (120) attachable to a therapeutic gas source (116) that communicates therapeutic gas pressure data to a therapeutic gas delivery system controller (129,144,164), a gas temperature (130) sensor positioned to measure gas temperature in the therapeutic gas source (116) that communicates therapeutic gas temperature data to the therapeutic gas delivery system controller (129,144,164), at least one flow controller (144,164) that communicates therapeutic gas flow rate data to the therapeutic gas delivery system controller (129,144,164), at least one flow sensor (146,148) that communicates flow rate data to the therapeutic gas delivery system controller (129,144,164), and at least one display (112) that communicates run-time-to-empty to a user of the therapeutic gas delivery system (100). The therapeutic gas delivery system controller (129,144,164) of the system (100) includes a processor that executes an algorithm to calculate the run-time-to-empty from the data received from the gas pressure sensor (120), temperature sensor (130), flow controller (144,164) and flow sensor (146,148), and directs the result to the display (112).
