Abstract

Therapy gas delivery systems 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 may include a gas pressure sensor attachable to a therapeutic gas source that communicates therapeutic gas pressure data to a therapeutic gas delivery system controller, a gas temperature sensor positioned to measure gas temperature in the therapeutic gas source that communicates therapeutic gas temperature data to the therapeutic gas delivery system controller, at least one flow controller that communicates therapeutic gas flow rate data to the therapeutic gas delivery system controller, at least one flow sensor that communicates flow rate data to the therapeutic gas delivery system controller, and at least one display that communicates run-time-to-empty to a user of the therapeutic gas delivery system. The therapeutic gas delivery system controller of the system includes a processor that executes an algorithm to calculate the run-time-to-empty from the data received from the gas pressure sensor, temperature sensor, flow controller and flow sensor, and directs the result to the display.

First claim

What is claimed is:

1 . A therapeutic gas source comprising:
a compressed gas cylinder of therapeutic gas; and at least one gas source identifier attached to the compressed gas cylinder, wherein the gas source identifier contains gas source identifier information comprising at least one of gas source volume, therapeutic gas identity, therapeutic gas expiration date, and therapeutic gas concentration supplied by the therapeutic gas source.

2 . The therapeutic gas source of claim 1 , wherein the gas source identifier is selected from the group consisting of RFID, a QR code, a bar code, or combinations thereof.

3 . The therapeutic gas source of claim 1 , wherein the therapeutic gas concentration is about 2000 ppm to about 10000 ppm.

4 . The therapeutic gas source of claim 3 , wherein the therapeutic gas concentration is about 4880 ppm.

5 . The therapeutic gas source of claim 1 , wherein the gas source volume is a wetted volume of the gas source.

6 . The therapeutic gas source of claim 1 , wherein the therapeutic gas is nitric oxide.

7 . The therapeutic gas source of claim 1 , wherein the therapeutic gas source further comprises a gas source valve operable to be received by a gas source coupling within at least one gas supply subsystem of a therapeutic gas delivery system.
