ABSTRACT:
A method and apparatus for measuring a gas partial pressure in a living body on the basis of the principle of polarography. A gas partial pressure sensor includes a biomedical electrode inserted in the living body. A temperature sensor is further provided to measure a temperature of the living body. A polarographic current value measured by the gas partial pressure sensor is corrected to a current value at a reference temperature depending on the temperature measured by the temperature sensor. Then the gas partial pressure at the reference temperature is determined based on a working curve which represents a relationship between the corrected polarographic current value and the gas partial pressure at the reference temperature.
