This paper is devoted to the problem of adequate mathematical modeling of the pulse wave using a 1D hemodynamics model. This is possible provided that the conditions of wave propagation and reflections are correctly established and translated into the model. We analyze how the propagation of the forward and backward waves in the model is affected by the boundary conditions, the choice of the filtration coefficient at the ends of terminal arteries, and the modeled vessel geometry. We also propose an equation of state based on experimental data acquired in vivo.
