Abstract
Described are methods and systems for delivering pharmaceutical gas to a patient. The methods and systems utilize a high flow valve and a low flow valve in parallel flow paths. The pharmaceutical gas may be provided as a pulse during the first half of the patient's inspiratory cycle.
Claims18
A nitric oxide delivery system comprising:
- an inlet to connect to a source of pharmaceutical gas comprising nitric oxide;
- an outlet to connect to a device that introduces the pharmaceutical gas to a patient;
- a low flow valve in fluid communication with the inlet and outlet, wherein the low flow valve delivers the pharmaceutical gas at a first flow rate;
- a high flow valve in fluid communication with the inlet and outlet and in parallel to the low flow valve, wherein the high flow valve delivers the pharmaceutical gas at a second flow rate that is higher than the first flow rate;
- and
- a gas control system that delivers a pulse of the pharmaceutical gas through one or more of the low flow valve and the high flow valve.
