Parametric differential approach for modeling the upper limb human vasculature

Conf Proc IEEE Eng Med Biol Soc. 2004:2006:742-5. doi: 10.1109/IEMBS.2004.1403265.

Abstract

A parametric approach is proposed for the characterization of the upper vascular tree. The novelty of the approach resides in it being differential: the processed signals are the photoplethysmograms obtained non-invasively from the left and right indexes. The investigated model is an ARX (auto-regressive with exogenous input) where the order has been estimated utilizing standard techniques. The model coefficients show a relatively high degree of stability.
