The pH is closer to the acidic level,so the primary disorder is acidosis.Compensated metabolic acidosis values include a pH of 7.35 to 7.39,PACO₂ below 35 mm Hg,and HCO₃- below 22 mEq/L.Uncompensated respiratory acidosis values include a pH below 7.35,PACO₂ above 45 mm Hg,and HCO₃? of 22 to 26 mEq/L.Compensated respiratory alkalosis values include a pH of 7.41 to 7.45,PACO₂ below 35 mm Hg,and HCO₃-below 22 mEq/L.Uncompensated metabolic alkalosis values include a pH above 7.45,PACO₂ of 35 to 45 mm Hg,and HCO₃? above 26 mEq/L.
