Abstract

Various systems generating nitric oxide are disclosed herein. According to one embodiment, the system includes a first gas source providing nitrogen dioxide mixed in air or oxygen, and a second gas source supplying compressed air and/or compressed oxygen. The system also includes a ventilator coupled to the first and second gas sources, wherein the ventilator is resistant to nitrogen dioxide. The ventilator regulates gas flow and allows for the adjustment of nitrogen dioxide concentration in the gas flow. The system further includes one or more conversion devices operably coupled to the ventilator where the conversion devices convert nitrogen dioxide into nitric oxide. A patient interface delivers nitric oxide to the patient and is operably coupled to the conversion devices. The system allows oxygen and nitric oxide levels to be varied independently.

Claims

1. A system for delivering nitric oxide to a patient, comprising:

a patient monitor configured to monitor blood oxygen level in the patient;

a gas source to provides a gas flow having a dosage amount of nitrogen dioxide based on the monitored blood oxygen level in the patient;

one or more conversion devices operably coupled to the gas source, wherein the conversion devices convert nitrogen dioxide into nitric oxide; and

a patient interface operably coupled to the conversion devices, wherein the patient interface delivers the dosage amount of the nitric oxide to the patient.

2. The system of claim 1, wherein the gas source includes a ventilator.

3. The system of claim 2, further comprising a humidifier positioned between the ventilator and the one or more conversion devices.

4. The system of claim 1, wherein the patient monitor includes an oxygen pulse oximeter.

5. The system of claim 4, further comprising a feedback controller that regulates the nitric oxide dose based on a reading from the oxygen pulse oximeter.

6. A method for delivering nitric oxide to a patient, comprising:

monitoring blood oxygen level in the patient;

providing a dosage amount of nitrogen dioxide based on the monitored blood oxygen level in the patient;

converting the nitrogen dioxide into nitric oxide; and

supplying the dosage amount of the nitric oxide to the patient.

7. The method of claim 6, wherein the gas source includes a ventilator.

8. The method of claim 7, further comprising a humidifing a gas including the nitric oxide.

9. The method of claim 6, wherein the patient is monitored with an oxygen pulse oximeter.
