Figure 2: Values of ambient temperature, pH, PaCO2, PaO2, HCO3-, and Hct for normothermic rats , untreated heat stressed rats , and heat stressed rats treated with whole body cooling (WBC) for 20 minute . Points represent mean ± SEM or 8 rats per group [*P < .05 in comparison with normothermic control; P < .05 in comparison with untreated heat stressed rats]. The duration of WBC is indicated by the dashed line. The hematocrit is also described.
