(A) Compensated metabolic alkalosis would be reflected by the following: pH within normal limit (7.35–7.45), PCO2 > 45 mm Hg, HCO3 >26 mEq/L. (B) Respiratory acidosis would be reflected by the following: pH < 7.35, PCO2 > 45 mm Hg, HCO3 within normal limits (22–26 mEq/L). (C) Partially compensated metabolic alkalosis would be reflected by the following: pH > 7.45, PCO2 > 45 mm Hg, HCO3 > 26 mEq/L. (D) Combined respiratory and metabolicacidosis would be reflected by the following: pH < 7.35, PCO2 > 45 mm Hg, HCO3 < 22 mEq/L.
