Abstract

A successful global vector field reconstruction from physiological signals is obtained for the first time. Data are generated by blood pressure and arterial diameter oscillations by using an arterial catheter with pressure transducer and an ultrasonic echo-tracking system, respectively. Results lead to the unambiguous evidence that such biological systems are characterized by a low-dimensional deterministic dynamical behavior. It is shown that a physiological system can be modelled from theknowledge of its behaviour only, as this has yet been done fortheoretical systems and for laboratory designed experiments.
