ABSTRACT
The value of oxygen saturation in venous blood, SvO2, has important clinical significance since it is related to the tissue oxygen utilization, which is related to the blood flow to the tissue and to its metabolism rate. However, existing pulse oximetry techniques are not suitable for blood in veins. In the current study we examine the feasibility of difference oximetry to assess SvO2 by using two near-infrared wavelengths and collecting the backscattered light from two photodetectors located at different distances from the light source.
