A computer aided set of equipment for impedance plethysmographic research has been presented. A simple linear model of blood circulation in a limb has been used. A comparative analysis of blood circulation parameters in lower extremities has been carried out manually as well as calculated automatically. Parameters such as the limb blood flow Qo, the tissue blood flow qo, maximum volume change (venous capacitance, VC), the venous outflow time constant Tv and the venous outflow index were automatically and traditionally calculated on the basis of curve lines recorded on thermal recorder. A high linear correlation has been observed between parameters calculated manually and with computer-aided techniques. The results obtained confirm the usefulness of the linear model of blood circulation in a limb for pressures occurring under the conditions of vein occlusion.
