Conversion of nitrogen dioxide (NO 2 ) to nitric oxide (NO)
First Claim
1. An apparatus for converting nitrogen dioxide to nitric oxide comprising a receptacle including an inlet, an outlet and an antioxidant, wherein the inlet is configured to receive a gas flow comprising nitrogen dioxide and fluidly communicate the gas flow through the receptacle to the outlet, such that the gas flow contacts the antioxidant inside the receptacle, and the antioxidant converts the nitrogen dioxide in the gas flow 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.
