Abstract:
Application of 1D modelling to arterial networks description provides a computational low cost alternative, compared to 2D/3D simulations. However, wall viscosity is usually neglected in numerical solutions. A simplified 1D tapered model was implemented, considering the vascular path between central (aortic, cBP) and peripheral (radial, rBP) arterial blood pressures. Simulated rBP was generated using cBP as the model input and then compared to rBP measurements obtained from young subjects. Different values of wall elasticity and wall viscosity were considered and goodness of fit (determination coefficient, R2) was assessed for each case. Acceptable values of R2 were obtained for all performed simulations, mainly in cases where wall viscosity was considered in the model calculations. Interaction between arterial wall viscosity and elasticity constitutes a relevant factor that to be considered in the implementation of computational models based on arterial networks, especially in terms of pulse pressure propagation. © 2016 IEEE.
