| Base deficit^ | 0 to -2 mEq/L | -2 to -6 mEq/L | -6 to -10 mEq/L | -10 or less mEq/L |
| Need for blood products | Monitor | Possible | Yes | Massive transfusion protocol |
^Base excess is the quantity of base (HCO3-, in mEq/L) that is above or below the normal range in the body. A negative number is called a base deficit and indicates metabolic acidosis.
