Interface windows presented to the students during some phases of an exercise which was held during the training course. Panel A represents the “principal” command box, panel B the “thoracic artificial lung” command box and panel C the “coronary model” command box. Users can perform a second level of choice for the representation of some circulatory districts from panel A. In addition using this command box it is possible changes network, ventricular and atrium parameters, it is possible choose different graphical representations and to store parameters and numerical waveforms values. Panel B presents commands to set “ON/OFF” TAL assistance, to change TAL configuration and its parameter values and to show the waveforms of pressure and flow of the TAL. Finally panel C presents commands to set “ON/OFF” four different representation of coronary circulation. Coronary network is assembled according to the same principle described in Figure 2. Panel C permits to change coronary parameter values and to show pressure and flow waveforms in different coronary districts. Panels D and E show the mean pressure, volume and flow values. In all other windows (F) the instantaneous pressure, volume and flow waveforms calculated in the various districts of the network are plotted.
