An apparatus for converting nitrogen dioxide (NO 2 ) to nitrogen oxide (NO) is disclosed. Inhalation of low levels of nitric oxide can quickly and safely reduce pulmonary hypertension in mammals. A nitric oxide delivery system that converts nitrogen dioxide to nitric oxide uses a surface active material such as silica gel that is coated with an aqueous solution of an antioxidant such as ascorbic acid.
