Bicarb deficit
Sodium bicarbonate replacement for metabolic acidosis: Bicarb deficit = 0.3 × weight × base deficit
Result
168 mEq
Common practice: replace ½ over the first hour, then re-check ABG.

- Bicarb deficit = 0.3 × 70 × 8 = 168 mEq
Clinical note:0.3 reflects extracellular fluid volume as % of body weight. Reserve bicarb for severe acidemia (pH < 7.10) with hemodynamic compromise; treat the cause. Watch for hypernatremia and paradoxical CSF acidosis. Education only.
