Claim 28:
29. An apparatus for generating nitric oxide comprising:
(i) a reaction chamber;
(ii) an inlet to provide a flow reactant gas comprising nitrogen and oxygen to the reaction chamber;
(iii) a pair of electrodes located in the reaction chamber and separated by a gap;
(iv) a flow meter for measuring a gas flow from an external regulated source to determine the flow of the reactant gas through the reaction chamber;
(v) an electronic control circuit in communication with the flow meter and the electrodes to generate an electric arc discharge across the gap, wherein the electronic control circuit is configured to control a pulse frequency of the electric arc discharge and a pulse duration of the electric arc discharge independent of the pulse frequency; wherein the pulse frequency of the electric arc discharge is within a range of 0.1 and 100 Hz, and the pulse duration of the electric arc discharge is within a range of 20 microseconds and 500 milliseconds, and wherein the electric arc discharge across the gap determines a concentration of nitric oxide generated in the reactant gas to produce a product gas comprising nitric oxide;
(vi) one or more additional sensors;
(vii) one or more filters; and
(viii) an outlet to provide the product gas comprising nitric oxide;
wherein the outlet is in communication with a nitric oxide applicator to deliver the product gas to a patient.
