Date Feb. 5, 1998In a method for the non-invasive determination of the oxygen saturation in tissue supplied with blood, the tissue is irradiated with red and infrared light and the DC and AC components of the emerging light are measured. During a first time interval, a calibration factor k is determined from the DC and AC components of the emerging light. During a second time interval, the oxygen saturation in the tissue is computed progressively from the DC components of the emerging light and the determined calibration factor k.
