An electrochemical sensor for continuous intravascular oxygen monitoring.

The intravascular PO2 sensor described in this paper essentialal routine use. The small dimensions of the sensor permit its introduction into the vessel through a conventional guiding catheter size 4 F or larger. With 5 F catheters, simultaneous blood sampling and/or blood pressure measurement is possible. The accuracy and stability of the sensor permit continuous PO2 measurement to be performed over several days.
