This paper dealt with the analysis of the dynamic pressure-flow relationships of the human brachial artery. One lumped analog circuit was proposed to represent this system, which was consisted from a series connected L and R_1 network terminated by a parallel connected C and R_2 network. Each of these network parameters were estimated from the actually recorded arterial pressure and flow waves at the root of this artery of 40 cases of human brachial arteries. The analog computation of the pulsatile arterial blood flow wave was carried out by giving the simultaneously recorded arterial pressure wave as an input. The results illustrated many undistinguishable resemblance between the actually recorded flow wave and the computed flow wave. The same procedure was tried to explain the flow disturbances in the patients caused by various reasons. The results of this analog simulation indicated the location and the nature of the flow disturbances along this arterial system for the purpose of the differential diagnosis.
