Abstract: An apparatus (10) and method for delivering a high partial pressure of a gas into a liquid. The apparatus includes a gas transfer device (12) with includes a housing (14) having upstream (16) and downstream (18) regions, between which there is located a gas-liquid contacting region (20) with contacting members (22) such as hollow microporous fibers. A reservoir (36) of gas supplied gas at a high pressure (P) to a flask (38) containing gas-depleted liquid and to the gas transfer device (12). The reservoir (36) of gas provides hydrostatic pressure for urging the liquid through the contacting members (22) and propelling the gas around the contacting members (32) so that the gas does not diffuse across the contacting members. The gas-enriched liquid is then conducted to a high resistance delivery channel (44) for administration to a site of interest with effervescence, bubble formation or significant disruption of laminar flow.

Abstract: A method and apparatus for delivering oxygen into an environment of interest, such as blood plasma (22), having the characteristic of a low concentration of oxygen before delivery. The method includes the steps of preparing a mixture of oxygen and liquid, compressing the mixture so that the oxygen dissolves in the liquid to form an oxygen-enriched liquid, delivering the oxygen-enriched liquid to a catheter having an internal diameter and length which retains the oxygen in solution and prevents the formation of bubbles, positioning the catheter in the environment of interest, and injecting the oxygen-enriched liquid into the environment through the catheter, such that the environment rapidly becomes enriched in oxygen. The apparatus includes a catheter with drawn silica tubing (20) having narrowly defined passages through which oxygen-enriched liquid passes to oxygenate blood plasma (22).

Abstract: Disclosed is a metalloporphyrin-ligand complex which includes (a) a meso-tetraphenylporphyrin, (b) a crown ether rigidly attached to the meso-tetraphenylporphyrin by covalent attachment on one side of the porphyrin to two diagonally opposing phenyl groups, (c) a metal bound to the pyrrole nitrogens of the portphyrin, (d) a bridge covalently linking two diagonally opposing phenyl groups on the other side of the porphyrin, effective to hinder mu -oxo dimer formation, and (e) a ligand having (i) a primary amine which is held noncovalently by the crown ether and (ii) a metal-coordinating atom which is coordinately bound to the metal. In another aspect, the invention includes a water-soluble oxygen carrier. The oxygen carrier includes a meso- alpha , alpha , alpha , alpha -tetrakis(o-propanoyl-amino)phenylporphyrin, in which the 3-carbons of the propanoyl groups are each covalently bound to an amine nitrogen, and iron or cobalt is bound to the pyrrole nitrogens of the porphyrin. The oxygen carrier also includes a ligand L for protecting the open face of the porphyrin form mu -oxo dimer formation.

Abstract: 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 (10); applying a high pressure to the mixture; warming the pressure vessel (10) and its contents to provide an aqueous suspension of the hydrate within liquid water formed from the ice upon warming; providing a conduit (32) in communication with a catheter (16), the catheter (16) having one or more high resistance exit ports (30); 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.
