Nitric oxide (NO) generating compositions can include a nitrite component, an acidifying component, and a support material configured to carry one of the nitrite component and the acidifying agent. In some examples, the support material can minimize NO generation prior to addition of an activating amount of a suitable solvent.

A method for making an NO-releasing polymeric composition, a discrete RSNO adduct is dissolved in a solvent to form a discrete RSNO adduct solution. A polymer material is soaked in the discrete RSNO adduct solution for a predetermined time to swell the polymer material and impregnate the polymer material with the discrete RSNO adduct.

A system for delivering a therapeutic amount of nitric oxide can include a reservoir assembly, a gas supply, and a delivery conduit including a first cartridge, wherein the first cartridge can include a surface-activated material saturated with an aqueous solution of a reducing agent.

A nitric oxide delivery system, which includes a gas bottle having nitrogen dioxide in air, converts nitrogen dioxide to nitric oxide and employs a surface-active material, such as silica gel, coated with an aqueous solution of antioxidant, such as ascorbic acid. A nitric oxide delivery system may be used to generate therapeutic gas including nitric oxide for use in delivering the therapeutic gas to a mammal.
