Fig. 3. Arterial pH ( A ) and central venous oxygen saturation (Scvpo2; B ) are shown at baseline (zero) and after 10 min of resuscitation (mean ± SEM; n = 5 for all values). # Significant differences with the mean value of the saline group. * Significant differences with epinephrine-treated animals. One symbol , P < 0.05; two symbols , P < 0.01; three symbols , P < 0.001. EPI = epinephrine-treated group; L = lipid-treated group; SALINE = control group.
