In this paper, a finite element (FE) modeling is used to model effects of the
arterial stiffness on the different signal patterns of the pulse transit time
(PTT). Several different breathing patterns of the three subjects are
measured with PTT signal and corresponding finite element model of the
straight elastic artery is applied. The computational fluid-structure model
provides arterial elastic behavior and fitting procedure was applied in order
to estimate Young’s module of stiffness of the artery. It was found that
approximately same elastic Young’s module can be fitted for specific subject
with different breathing patterns which validate this methodology for
possible noninvasive determination of the arterial stiffness.
Keywords: arterial stiffness, finite element modeling, microcontroller, pulse transit time
