Conversion of nitrogen dioxide (NO2) to nitric oxide (NO)
First Claim
1. A method of delivering nitric oxide to a human comprising converting nitrogen dioxide to nitric oxide by fluidly communicating a gas flow including nitrogen dioxide to a receptacle including an inlet, an outlet, and a surface-active material coated with an aqueous solution of an antioxidant, wherein the antioxidant includes ascorbic acid, alpha tocopherol or gamma tocopherol, wherein the inlet is configured to receive the gas flow and fluidly communicate the gas flow to the outlet through the surface-active material such that nitrogen dioxide in the gas flow is converted to nitric oxide.

Abstract
Inhalation of low levels of nitric oxide can rapidly and safely decrease pulmonary hypertension in mammals. A nitric oxide delivery system that converts nitrogen dioxide to nitric oxide employs a surface-active material, such as silica gel, coated with an aqueous solution of antioxidant, such as ascorbic acid.
