Figure 4.

Mean effects (± standard error of the mean) of a fluid bolus (40 mL/kg intravenously over 40 min) in study 1 for central venous pressure (CVP), pulmonary artery occlusion pressure (PAOP), mean arterial blood pressure (MAP), and cardiac index (CI) in animals receiving 24-h infusions with low (LD) or high (HD) doses of edema (ETx) or lethal (LeTx) toxin or in controls. P values are for the comparison between the effect of fluid in toxin animals versus control (p^α) and for the interaction between time and these comparisons (p^β).
