To investigate the mechanism of pulse wave propagation and reflection in human arteries and to propose the manner of utilization is the object of this study. The experimental apparatus simulating the human circulatory system composed of silicon tube to examine the pulse wave propagation and reflection with and without branches is developed. Special focus is paid on the effect of seven parameters affecting waveform, PWV (Pulse Wave Velocity) and PV Loop (Pressure-Velocity Loop). As a result, PV Loop is found to include more information on the tube characteristics, impedance, boundary condition, tube connection construction and reflection situations compared with PWV.
