Abstract :
A theoretical study has been performed to assess how the pulse pressure variation affects results of the arterial compliance measurement. Two asymmetric arctangent models for the arterial pressure-volume (P-V) relationship have been used by applying model-based and amplitude-based compliance estimation techniques. The results demonstrate that for near- zero transmural pressure the model-based values of the compliance are systematically higher than those estimated by the amplitude-based calculation technique. Increasing of the pulse pressure amplitude causes a considerable reduction in the amplitude-based compliance estimate. For & P-V relationship with a lower steepness, a reduction in the amplitude-based compliance versus transmural pressure is smaller.
