1. A wearable nitric oxide generation system comprising:

  • a housing configured to be wearable;

    a reactant gas flow path located in the housing, the reactant gas flow path configured to provide release of a pressurized reactant gas at specific flow rates to one or more plasma chambers;

    one or more electrodes located in the one or more plasma chambers configured to generate a product gas containing nitric oxide using a flow of the reactant gas through the one or more plasma chambers;

    a controller configured to regulate the amount of nitric oxide generated in the reactant gas;

    a disposable cartridge including one or more scavenger paths configured to remove NO2 from the product gas generated by the one or more plasma chambers, anda connector to deliver the product gas to a patient delivery device;

    wherein the controller measures a resonant frequency of a high voltage circuit and controls a frequency and a duty cycle of an AC waveform to maximize excitation of the high voltage circuit; and

    wherein the resonant frequency is determined throughout a service life of the system to accommodate changes in environmental conditions, system wear, and/or manufacturing variance.
