Abstract: Embodiments of nitric oxide (NO) generation apparatuses, systems, and methods are provided. In some embodiments, an NO generation apparatus may include a reaction chamber having a liquid region and a gas region. The liquid region may be configured to contain a reaction medium and the gas region may be configured to contain a product gas comprising NO. The NO generation apparatus may also include a plurality of electrodes disposed in the reaction medium, and may include an energy source electrically connected to the plurality of electrodes and configured to apply a predetermined voltage or a predetermined current to at least one of the plurality of electrodes to generate NO. The NO generation apparatus may also include an inlet circuit configured to receive a carrier gas, and may include at least one sparger in fluid communication with the inlet circuit and configured to emanate bubbles of the carrier gas in the reaction medium.
