Respiratory acidosis: > 45 mmHg Normal: 22 - 26 mEq/L Normal: -2 to +2 mmol/L

Respiratory alkalosis: <35 mmHg Metabolic alkalosis: > 26 mEq/L Mild -4 to -6
(< 4.6 kPa)
[Standard Bicarbonate: Calculated Moderate -6 to -9
value. Similar to the base excess. It
is defined as the calculated Marked -9 to -13
bicarbonate concentration of the
sample corrected to a PCO2 of Severe to < -13
5.3kPa (40mmHg).
Metabolic alkalosis: > +2 mmol/L
Severe > +13
Marked 9 to 13
Moderate 6 to 9
Mild 4 to 6
[Base excess (BE) is the mmol/L of base
that needs to be removed to bring the pH
back to normal when PCO2 is corrected
to 5.3 kPa or 40 mmHg. During the
calculation any change in pH due to the
PCO2 of the sample is eliminated,
therefore, the base excess reflects only
the metabolic component of any
disturbance of acid base balance.]
