Values are means ± SD. Baseline and hemodilution included all the animals. No significant differences were detected between baseline or hemodilution values between the experimental groups.

Hct, hematocrit; Hb, hemoglobin; P_aO₂, arterial partial O₂ pressure; P_aCO₂, arterial partial pressure of CO₂; BE_a, arterial base excess.
