Equation for base excess

Base excess can be estimated from the bicarbonate concentration ([HCO3 ]) and pH by the equation: with units of mEq/L. The same can be alternatively expressed as Calculations are based on the Henderson-Hasselbalch equation: Ultimately the end result is: WebBase excess is defined as the negative value of the concentration ( c) of titratable (t) hydrogen ion in blood (B); thus BE = – c tH +B. It may be determined directly experimentally. The endpoint of in vitro titration is pH …
