Systems and methods for nitric oxide generation with humidity control

A system for generating nitric oxide comprising:

• at least one plasma generator configured to generate a product gas containing nitric oxide from a reactant gas;
• and
• at least one controller configured to regulate the amount of nitric oxide in the product gas using one or more parameters as an input to the controller, the one or more parameters relating to at least one of the reactant gas, the product gas, and an inspiratory gas into which at least a portion of the product gas flows;
• a humidity control device configured to communicate with the at least one controller such that the controller can use the humidity control device to alter the humidity within at least one of the reactant gas and the product gas,
• wherein at least one parameter is humidity information in at least one of the reactant gas and the product gas to achieve a target nitric oxide production level.

• a scrubber configured to remove nitric dioxide (NO2) from the product gas;
• a humidity control device configured to alter a water content of at least one of the reactant gas and the product gas to control humidity within the system;
• and
• one or more humidity sensors configured to communicate humidity information with the at least one controller.
