ABSTRACT:
A probe adapted for insertion in living tissue for measuring oxygen partial pressure and temperature at a plurality of sites in living tissue is provided. A temperature sensitive resistor is positioned adjacent each of a plurality of oxygen sensors so that the oxygen partial pressure measured can be adjusted for tissue temperature. The probe substrate has thermal properties similar to living tissue and the resistors are formed of a material having a temperature sensitive resistance. Temperature at each temperature sensitive resistor is obtained by measuring resistance with a four point measurement and correlating the resistance to temperature.
