Abstract
Oxygen partial pressure and temperature are measured in living tissue by inserting a thin probe into living tissue. The probe includes a plurality of spatially separated thermal sensors secured to the probe substrate. A plurality of oxygen sensors is positioned along the length of the probe substrate and each oxygen sensor is associated with and positioned adjacent to or is an integral part of one of the thermal sensors. Electrical parameters of the sensors located on the probe are measured and used to determine oxygen partial pressure and to determine temperature at each of a plurality of sites along the probe.
