Electrodes for nitric oxide generation

A nitric oxide (NO) generation system, comprising:

• a plasma chamber comprising:
• at least one pair of electrodes configured to generate a product gas containing NO from a flow of a reactant gas, the at least one pair of electrodes having a first end and a second end with a length therebetween such that a plasma produced is carried by the flow of the reactant gas and glides along the length of the at least one pair of electrodes from the first end towards the second end;
• and
• at least one nozzle through which the reactant gas flows into the plasma chamber to the at least one pair of electrodes;
• a controller configured to regulate the amount of nitric oxide in the product gas by the at least one pair of electrodes using one or more parameters as an input to the controller, the one or more parameters including information from a plurality of sensors configured to collect information relating to at least one of the reactant gas, the product gas, and a medical gas into which the product gas flows;
• and
• a replaceable cartridge configured to include the plasma chamber and the at least one pair of electrodes, the replaceable cartridge having one or more connections for removably connecting the replaceable cartridge to the controller.
