Full Circulatory Network with Pneumatic Pulsatile Left Ventricular Assist Device (LVAD).

In the electrical analogue the pneumatic pulsatile left ventricular assist device (LVAD) can be connected in "serie" or in "parallel" mode. When the LVAD is connected in "serie" (dashed green line) the devices takes blood from the left ventricle and ejects it in the aorta (continuous red line). When the LVAD is connected in "parallel" (dashed blue line) the devices takes blood from the left atrium and ejects it in the aorta. Inside the software the LVAD is implemented as described in "Pulsatile Flow Pump" section. The LVAD can be driven in "syncronized", "syncronized with delay" and "full/empty" mode. Both ventricles and atria are modelled as descrimed in "Numerical Heart Model (1)" section. Systemic arterial (pulmonary) and venous sections are implemented as described in "Systemic Network 1" ("Pulmonary Network 1") section. The coronary network can be simulated using one of the six different models described in "Coronary Circulation" slides.

Full Circulatory Network with Pneumatic Pulsatile Right Ventricular Assist Device (RVAD).

In the electrical analogue the pneumatic pulsatile right ventricular assist device (RVAD) can be connected in "serie" or in "parallel" mode. When the RVAD is connected in "serie" (dashed green line) the devices takes blood from the right ventricle and ejects it in the pulmonary artery (continuous red line). When the LVAD is connected in "parallel" (dashed blue line) the devices takes blood from the right atrium and ejects it in the pulmonary artery. Inside the software the RVAD is implemented as described in "Pulsatile Flow Pump" section. The RVAD can be driven in "syncronized", "syncronized with delay" and "full/empty" mode.

Full Circulatory Network with Splanchnic, Extraslanchnic and Active Muscle Circulation and with Pulmonary Arterial Section (TCM). Left Ventricular Assist Device (LVAD) is Realized with Hemopump.

In this cardiocirculatory network the LVAD (Hemopump) produces a continuous blood flow. In CARDIOSIM© software simulator the right circulatory assistance is implemented as described in "Continuous Flow Pump (Axial Flow Pump)" section. The Hemopump thakes blood from the left ventricle and ejects it in the aorta. The systemic circulation is modelled as described in "Systemic Network 4" slide. The pulmonary circulation is implemented as described in "Pulmunary Network 3" section. In the electical analogue Pt represents the mean intrathoracic pressure. Changing Pt value it is possible simulate the effects induced by mechanical ventilatory assistance (MVA). The coronary network can be simulated using one of the six different models described in "Coronary Circulation" slides.
