Figure 3From: Using a human cardiovascular-respiratory model to characterize cardiac tamponade and pulsus paradoxusCirculatory Indices as a Function of Pericardial Volume. Percent change in circulatory indices as a function of pericardial volume (VPERI) for the model (diamonds) and patient data (squares) from [3]. Heart rate increases with VPERI up to 1000 ml (A), whereas cardiac output (B), and mean arterial pressure (C) decrease. Dotted line indicates point of significant deviation from control.Back to article page
