Abstract

See full text

A method of gasification of an environment having the characteristic of a low concentration of gas. The method is particularly suited for oxygenation of hypoxemic blood. The method comprises the steps of preparing a powdered oxygen hydrate; mixing the hydrate with powdered ice; pulverizing the mixture of the hydrate and the ice into small particles; encapsulating the mixture of the hydrate and the ice within a pressure vessel; applying a high pressure to the mixture; warming the pressure vessel and its contents to provide an aqueous suspension of the hydrate within liquid water formed from the ice upon warming; providing a conduit in communication with a catheter, the catheter having one or more high resistance exit ports; and intravenous injection of the suspension of particles at a rate which permits mixing of the hydrate with its environment before decomposition of the gas hydrate or bubble coalescence can occur.
