Figure 1. Experimental protocol, temperature, and hemodynamic parameters.

A, Experimental protocol illustrating the different procedures. After resuscitation, animals were randomly assigned to a conventional follow‐up under normothermic mechanical ventilation (control group, n=6) or to hypothermic total liquid ventilation (TLV; n=6). A third group was submitted to a sham procedure with no cardiac arrest (n=5). Animals were excluded if resumption of spontaneous circulation (ROSC) was not achieved in <10 minutes after the beginning of cardiopulmonary resuscitation. B, Esophageal and rectal temperatures, mean arterial pressure, heart rate, and epinephrine infusion rate throughout the experimental protocol in the different groups. Data are expressed as mean±SEM. Statistical comparisons were only made between groups but not among different time points; *P<0.05 vs corresponding sham; ^† P<0.05 vs corresponding Control. VF indicates ventricular fibrillation.
