Post-occlusive reactive hyperemia in patients with peripheral vascular disease.
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.
