C.II-24. The arterial blood gases and electrolytes during CPB are as follows: pH, 7.36; Paco2, 42 mm Hg; Pao2, 449 mm Hg; CO2 content, 24 mEq/L; sodium (Na), 128 mEq/L; potassium (K), 5.8 mEq/L; glucose, 180 mg/dL; and hematocrit, 20%. The patient's temperature is 27 °C (80.6 °F). At what temperature are blood gases measured? How would you correct the blood gases according to the patient's body temperature? Would you treat the arterial blood gases measured at 37 °C (98.6 °F) or at the patient's body temperature? i
