The Effects of Blood Viscoelasticity on the Pulse Wave in Arteries

摘要: 以Womersley理论为基础,将动脉中脉搏波复波速所满足的频率方程推广到粘弹血液情形,得到了线性粘弹血管和线性粘弹血液情况下脉搏波复波速的一般关系式。应用此关系式,讨论了血液粘弹性对动脉中脉搏波波速和波的衰减的影响。结果表明,血液弹性对脉搏波传播的影响小于血管粘性的影响;对大动脉,血液弹性对脉搏波传播的影响可忽略。

Abstract: Based on Womersley's theory,the frequency equation satisfied by a complex wave velocity of a pulse wave in arteries was generalized to viscoelastic blood,a general formula of the complex wave velocity with regard to both linearly viscoelastic arteries and linearly viscolelastic blood was obtained,and the effects of the viscoelastic property of blood on the phase velocity and the wave attenuation of the pulse wave using the formula systematically was discussed.It is concluded that the influence of the blood elasticity on the wave propagation of a pulse wave in arteries is weaker than that of the arterial viscosity and may be neglected in larger arteries.
