Abstract
A non-invasive method of objectively determining, in vivo, the rate of oxygen utilization in peripheral tissue by spectral measuring means, which involves isolating a segment of blood in the tissue with a clamp or tourniquet, and obtaining rapid, successive spectral curves of the oxyhemoglobin in the occluded area, to and from selected wavelengths of light, and measuring the time-space relationship between a rapidly moving portion of the spectral curve and a slower moving adjacent portion of the same curve, from the moment of occlusion, to establish a rate of reduction of the oxyhemoglobin in the tissue which is directly correlated to the rate of oxygen utilization.
