Synthesis of nitric oxide gas for inhalation

An apparatus comprising:

• an inlet configured to receive a reactant gas containing nitrogen and oxygen;
• an outlet configured to provide a product gas containing nitric oxide, wherein the product gas is formed by a synthesis of the reactant gas;
• a reaction chamber arranged between the inlet and the outlet;
• one or more pairs of electrodes within the reaction chamber and configured to initiate electric arcs to synthesize the reactant gas to the product gas;
• a sensor configured to measure a flow of a gas in a ventilator into which the product gas is provided through the outlet;
• and
• a controller in communication with the one or more pairs of electrodes and the sensor, the controller being configured to:
• adjust one or more conditions within the reaction chamber based on the measured flow of gas in the ventilator to control a concentration of nitric oxide in the product gas.

• a reaction chamber arranged between the inlet and the outlet;
• one or more pairs of electrodes within the reaction chamber and configured to initiate a series of electric arcs to synthesize the reactant gas to the product gas, the one or more pairs of electrodes include iridium to minimize a concentration of NO2 in the product gas;
• a sensor configured to measure a flow of a gas in a ventilator into which the product gas is provided through the outlet;
• and
• a controller in communication with the one or more pairs of electrodes and the sensor, the controller being configured to adjust one or more conditions within the reaction chamber to control a concentration of nitric oxide in the product gas based on the measured flow to control a concentration of nitric oxide in the product gas.

A method for generating nitric oxide, the method comprising:

• providing a reactant gas containing nitrogen and oxygen to a reaction chamber having one or more pairs of electrodes therein,
• initiating a series of electric arcs in the reaction chamber to synthesize the reactant gas to a product gas containing nitric oxide;
• measuring a flow of a gas in a ventilator into which the product gas is provided;
• and
• adjusting one or more conditions within the reaction chamber based on the measured flow of gas in the ventilator to control a concentration of nitric oxide in the product gas.
