Abstract
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.
Claims6
A method of delivering nitric oxide comprising:
- releasing nitrogen dioxide from a reservoir through a restrictor tube into a delivery conduit, wherein the reservoir includes a nitrogen dioxide source and the restrictor;
- passing a gas from a gas supply into the delivery conduit which allows the gas from the gas supply and the nitrogen dioxide to mix in the delivery conduit;
- passing the gas and nitrogen dioxide mixture through at least one cartridge, wherein the cartridge comprises a surface-active and a reducing agent;
- and
- delivering nitric oxide from an outlet of the delivery conduit.
