1. A method of generating nitric oxide, the method comprising:

  • pumping a filtered gas into a reaction chamber, wherein the filtered gas is ambient air that has been filtered to remove oxygen and moisture;

    providing a mixture of reactants in a solid form comprising at a mixture of a calcined chromium oxide compound in combination with, a nitrite compound and a nitrate compound in the reaction chamber;

    activating the reactants to initiate a reaction generating a nitric oxide gas without the use of a liquid or a solution;

    evacuating the nitric oxide gas away from the reaction chamber in a closed conduit to inhibit further heating thereof and to resist further reaction of the nitric oxide gas;

    filtering the nitric oxide gas after the reaction; and

    delivering the nitric oxide at substantially ambient conditions to a user to provide a therapeutically safe concentration of nitric oxide.
