Abstrakt		In this preliminary study we examined the applicability of near infrared spectroscopy (NIRS) and laser Doppler flowmetry (LDF) for quantification of postocclusive reactive hyperemia (PORH) in patients with peripheral vascular disease and in healthy volunteers. The main goal was to quantify relatively the degree of circulatory disorder in patients as opposed to healthy subjects. Concentration changes of oxy- and deoxyhemoglobin, blood flow and oxygen partial tension during and after arterial occlusion on thigh were measured in 3 patients and 3 healthy volunteers. The results of our preliminary study demonstrate that NIRS and LDF appear to be reliable noninvasive methods in evaluation of circulatory disorder.
