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.

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.| File | Dimensione del file | Formato | |
