ABSTRACT:
Apparatus employing a non-invasive method for objectively determining in vivo, the rate of oxygen utilization in peripheral tissue by spectral measuring means, containing a light source, a clamp or tourniquet for occluding a segment of blood in the tissue, means for transmitting the light through the isolated segment of blood to pick up the spectral values of the oxyhemoglobin for two selected wavelengths, wherein the rate of reduction of the oxyhemoglobin of the blood as determined at one wavelength is faster that the rate of reduction of the oxyhemoglobin at the other wavelength, means for converting the spectral values individually for the two selected wavelengths into current flow, and means for determining the time-space relationship between the changing spectral values of the two selected wavelengths, from the moment of occlusion.
