Abstract :
To develop the noninvasive measurement method of circulatory parameters by analyzing the waveforms of digital plethysmograms (DPTG), mathematical modeling of input (ventricular ejection)/output (observed DPTG waveforms) relations was performed. It is well known that human DPTG is chaotic. Among several parametric system identification methods, the BJ model sufficiently fitted the observed waveforms
