A method for controlling nitrogen oxide (NOx) includes adjusting a flow rate of d gas injected into an arc-type plasma generating device, and identifying a concentration of the generated nitrogen oxide, while adjusting an amount of energy per unit flow rate of the injected gas.

Systems and methods for nitric oxide (NO) delivery are provided. A NO delivery system can include one or more pairs of electrodes configured to ionize a reactant gas into an NO-containing product gas, a delivery line to deliver at least a portion of the product gas into an inspiratory flow of gas, and a controller. The controller is configured to control an amount of NO in the product gas generated by the one or more pairs of electrodes using one or more parameters as input to the at least one controller. One of the parameters is a dilution value derived as a function of an inspiratory flow rate and a target inspiratory gas NO concentration level. The dilution value is used by the controller to set a flow rate of the product gas injected into the inspiratory flow and to determine a target concentration of NO in the product gas.
