Analysis of Impedance Matching Conditions for Arterial Circulation by Electrical Circuit Model

Abstract

Impedance matching condition was investigated by an equivalent electrical circuit model which simulated circulation at the region of femoral and tibial arteries. There is a terminal resistance that is known to minimize the blood flow impedance. The calculated results exhibited that the minimum impedance was influenced by the elastic modulus and the radius of artery. The present results afford important information for a plantation of vascular graft as a replacement of sclerotic artery.
