Abstract
An apparatus and a method for non-invasively measuring oxygen partial pressure in a living body in which light is thrown on a living body to be measured, the oxygen saturation of the living body is obtained from the light absorption spectrum or light scattering spectrum thereof, the temperature and/or pH of the living body is obtained from a nuclear magnetic resonance signal from the living body, and the oxygen partial pressure in the living body, useful for the diagnosis thereof, is determined on the basis of not only the oxygen saturation but also the temperature and/or pH of the living body.
