Abstract

Pulse Wave Velocity (PWV) monitoring is a well-established method for both the diagnosis and prevention of cardiovascular diseases. Over the years, many arterial simulators have been made to study PWV dependency on the mechanical and geometrical characteristics of arterial surrogates; in particular, some of them are able to vary the tensional state of vessel walls to cause a change in PWV values. In this paper, a novel arterial simulator is presented, capable of varying the PWV of an arterial surrogate by acting independently on its inner and outer pressures. The simulator under assessment can manage pressures up to three times greater than the atmospheric one. This characteristic provides the possibility to explore many tensional states compared to its predecessors. The experimental outcomes confirm its working principle and an increasing trend in PWV is found. The result uncertainties are up to 10% of the corresponding PWV value. I
