Abstract: We measured tissue oxygen saturation (StO2) changes during a post‐occlusive reactive hyperemia (PORH) test on lower extremities of peripheral vascular disease (PVD) patients and healthy controls. The StO2 changes were measured by the near‐infrared tissue oximeter prototyped by ViOptix Inc. We found that PVD indicators may include the post‐occlusive StO2 reperfusion rate, the time duration of the reperfusion phase in a PORH test, and the StO2 dispersion rate in reactive hyperemia. We suggest critical values of these indicators for PVD assessments.
