LABORATORY INDICATIONS OF ACID-BASE IMBALANCE
SIGN NORMAL INTERPRETATION
pH 7.35-7.45 Less than 7.35 —>acidosisMore than 7.45 —>alkalosis
PaCO2 35-45 mm Hg Less than 35 —>respiratory alkalosisMore than 45 —>respiratory acidosis
BICARBONATE(HCO3-)
22-26 mEq/L Less than 22 —> metabolic acidosisMore than 26 —> metabolic alkalosis
BASEEXCESS/DEFICIT
+2 to -2 mEq/L Less than -2 —> metabolic acidosisMore than +2 —>metabolic alkalosis
OXYGENSATURATION(THE AMOUNTOF HEMOGLOBINCOMBINED WITHOXYGEN)
95-98%
PaO2 80 to 100 mm Hg May be greater than 100 if patient ison oxygen and less than 75 if thereis a pulmonary problem.
