ABSTRACT:
This invention relates to an electrochemical sensor system for the simultaneous and continuous measurement of the partial pressure of oxygen PO.sub.2 and carbon dioxide partial pressure PCO.sub.2 in fluids. The electrochemical sensor of the present invention is particularly useful for intra-arterial measuring PCO.sub.2 and PO.sub.2 in blood and is readily adapted to transcutaneous measurement of these blood gases by the addition of a heating element and minor configurational changes.
