ABSTRACT:
An apparatus 10 and method for delivering a high partial pressure of a gas into a liquid. The apparatus has a gas transfer device 12 with a housing 14 that includes 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 supplies the gas at a high pressure (P) to a flask 38 of 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 22 so that the gas does not diffuse across the contacting members 22. The gas-enriched liquid is then ducted to a high resistance delivery channel 44 for administration to a site of interest without effervescence, bubble formation, or significant disruption of laminar flow.
