Measurement and Utilization of In Vivo Blood-Pressure Transfer Functions of Dog and Chicken Aortas

A method for determining the essential parameters of the aorta, namely the geometric taper, area, hoop elasticity, and effective loss factor, from in vivo pressure measurements is presented. A nonuniform hybrid model, having both geometric and elastic taper and terminated in a reflectionless impedance at the femoral bifurcation, is utilized.
