A Proposed Distributed Parameter Model for Studying the Effects of Acceleration Forces upon the Arterial System

摘要

A distributed parameter mathematical representation is obtained for the arterial system under stress resulting from headward acceleration. Assuming steady state conditions, solutions are obtained for the pressure and flow dynamics of the system in terms of the parameter distributions depicting the effects of viscous resistance, viscous inertance, compliance of the vessels and fluid outflow through the tubes. A computational scheme is proposed for determining the parameters of the system, based upon the difference between the measured system response under stress and the solution of the mathematical model.
