Análisis de Señales de Presión y Diámetro Arterial en Base a Geometría Fractal

Arterial system dynamic approach necessarily implies the analysis of the interaction between the blood flow and the arterial wall. More precisely, the afore-mentioned relationship is mediated by endothelial cells intervention. Biological systems behavior is controlled by nonlinear reactions, and should be evaluated by means of representative methods, such as fractal geometry. In the present study, endothelial response related signals (arterial pressure and diameter) processing is proposed, by applying fractal characterization techniques, for different mean blood flow regimes and in presence and absence of endothelial tissue.
