A method and apparatus for delivering oxygen into an environment of interest, such as blood plasma, having the characteristic of a low concentration of oxygen before delivery. The method includes the steps of preparing a mixture of oxygen and a 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 having narrowly defined passages through which oxygen-enriched liquid passes to oxygenate blood plasma. |
