An approach to computer automation of the extracorporeal circulation.

In order to move towards extracorporeal circulation (ECC) automation, a virtual simulation of the process was designed. The ECC model is composed of a virtual patient linked to a virtual ECC circuit. A user interface panel allows to set control parameters for the simulation and to visualize results. It is possible to switch between manual and automatic control. Meaningful hemodynamic and hematochemical variables are continuously shown along with a score (from 0 to 10). The virtual model can play a crucial role in educating and training the personnel devoted to the managing of the heart-lung machine.
