Device for optically determining physiological variables in perfused tissue comprises light sources, a photo-detector, a control unit delivering control signals to the light sources, and an evaluation unit
Device for optically determining physiological variables in perfused tissue comprises a first light source and a second light source each emitting a light beam of a first or a second predetermined wavelength, a photo-detector (2) arranged so that it detects light passing through the tissue and/or back-scattered light, a control unit delivering control signals to the light sources, and an evaluation unit (7) connected to the output of the photo-detector. The evaluation unit delivers an output signal to an interface connected to the evaluation unit.
