Abstract
An instrument for withdrawing equilibrated blood gases in vivo, which comprises a tubular gas permeable membrane inserted through a cannular into the blood stream. In preferred form, the tubular membrane comprises a continuous conduit in contact with the blood. An inlet supply gas terminal is constructed for connection to a carrier gas source, and an outlet gas terminal, for connection to an appropriate analyzer. In preferred forms of the invention, a heater maintains the equilibrated gases at above normal body temperature as they pass to the analyzer; and a port is provided for drawing blood samples from the area being analyzed without dislodging the catheter.
