Abstract :
Peripheral vasomotion, interstitial liquid exchange and cardiovascular system behaviour during extra corporeal circulation are investigated by means of a lumped parameter model of the systemic arterial circulation, made by 63 RCL segments and 30 peripheral districts. A considerable autoregulatory activity of peripheral districts was found: peripheral blood flow keeps constant over a wide pressure range and, when regulated, oscillates around its physiological value. Then parameters alterations deriving from extra corporeal circulation are considered, observing peripheral and large vessel response.
