Using a human cardiovascular-respiratory model to characterize cardiac tamponade and pulsus paradoxus

Table 2 Diastolic and Systolic Venous Return Volumes with Pericardial Effusion

Venous return volumes during diastole and systole and the diastolic-to-systolic (D/S) volume ratios for increasing levels of effusion. For the right heart, vena caval return volume is given by V_VC,D for diastole and V_VC,S for systole. Similarly for the left heart, pulmonary venous return volume is given by V_PV,D for diastole and V_PV,S for systole. The D/S volume ratio decreases with increasing effusion.
