Abstract
A therapeutic oxygen-nitric oxide gas mixture is produced by passing air, oxygen-enriched air or air containing a small amount of ammonia over a noble metal catalyst at an elevated temperature. The product gas containing nitric oxide and a small amount of nitrogen dioxide is passed through a bed of an adsorbent which preferentially adsorbs nitrogen dioxide to produce nitric oxide-containing air suitable for administering to humans as an inhalant.
