  1. Results of blood gas analysis, electrolytes, and metabolic variables (total protein (Tp), partial pressure of carbon dioxide (pCO2), partial pressure of oxygen (pO2), bicarbonate (HCO3), base excess (BE), packed cell volume (PCV), sodium (Na+), potassium (K+), calcium (Ca2+), chloride (Cl), glucose, lactate, and lactate dehydrogenase (LDH)) of arterial (a) and venous (v) samples taken at 0, 60, 120, 180, and 240 min. Sample size (N), mean, standard derivation (SD), median, range, and reference intervals are presented. A maximum of 45 samples was used where all samples of all specimens were available, otherwise this number is smaller. Reference intervals are shown in the right column [18] and statistically significant (P < 0.05) differences are marked with an arrow up if they are higher or down if they are lower than reference intervals
