Base excess

In human physiology, base excess (see: base) refers to the amount of acid required to return the blood pH of an individual to the normal value (pH 7.4). The value is usually reported in units of (mEq/L). The normal value is somewhere between -3 to +3.

The term and concept were first introduced by Astrup and Siggaard-Andersen in 1958.

Actual and standard

Actual base excess is the base excess in the blood.

Standard base excess is the value of base excess when the hemoglobin-value of 5g/l. This gives a better view of the base excess of the entire extracellular fluid. [1]
