Paper Abstract

We report results of a feasibility clinical evaluation of the near-infrared Photonify Tissue Spectrometer in detection of peripheral vascular disease (PVD). In the evaluation, using a blood pressured cuff, we measure changes in oxygen saturation (StO2) during a temporary occlusion of blood inflow. We use the post-occlusive StO2 recovery rate and the time needed for 80% recovery as parameters to differentiate healthy subjects from subjects with PVD, and obtained high diagnostic accuracy in 19 subjects enrolled in the clinical evaluation. This may suggest that the tissue spectrometer could be useful in diagnosis of PVD.
