Edit this slide

Right Circulatory Network with Pulmonatry Arterial Tree Modelled with RLC Elements.

Open loop network with: atrial reservoir (preload), right ventricle and pulmonary arterial tree.  The behavior of the native ventricle is implemented as reported in "Numerical Hart Model (1)". RAP is the right atrial pressure and RVP is the right ventricular pressure. TV (PV) is the tricuspid (pulmonary) valve. The pulmonary arterial tree is modelled with RLC elements (Rcp, Lp and Cap). Rap is the variable pulmonary arterial peripheral resistance. Qri is the (Qro) input (output) right ventricular flow. TV and PV are modelled using resistances and diodes when the valve regurgitation is not simulated.TV and PV are implemented with the resistance (Rri) and the inverese resistance (Rinv) when the valve regurgitation is simulated.

Right Circulatory Network with Main, Small, Arteriole and Capillary Pulmonatry Circulation.

Open loop network with: atrial reservoir (preload), right ventricle and pulmonary arterial tree devoded in three branches.  The behavior of the native ventricle is implemented as reported in "Numerical Hart Model (1)". RAP is the right atrial pressure and RVP is the right ventricular pressure. TV (PV) is the tricuspid (pulmonary) valve. The main pulmonary artery is modelled with RLC elements (Rpam, Lpam and Cpam), the behavior of the small pulmonary artery is reproduced with Rpas, Lpas and Cpas, the pulmonary arteriole and capillary circulation is implemented using Rpac, Lpac and Cpac. Rap is the variable pulmonary peripheral resistance. Qri is the (Qro) input (output) right ventricular flow. TV and PV are modelled using resistances and diodes when the valve regurgitation is not simulated.TV is implemented with the resistance (Rri) and the inverese resistance (Rinv) when the valve regurgitation is simulated.
