BE = HCO−. 3 −24.8 + β · (pH−7.40) where 24.8 and 7.40 are the reference, ideal HCO3− (mmol/L) and pH values, and β is the bufer power (mmol/L) of non-carbonic weak acids [7, 8], which can either be a constant value (16.2 mmol/L) or computed as a function of hemoglobin concentration (assuming a constant protein concentration of 70 g/L) [9, 10].
May 31, 2022 · To overcome this limitation, Siggaard-Andersen introduced the base excess (BE), i.e. the “excess” (either positive or negative) of the actual BB as compared to the Normal BB (NBB). BE = Δ BB = BB - NBB
What is the base excess? Base excess (BE) measures all bases, not just bicarbonate. However, because bicarbonate is the greater part of the base buffer, for most practical interpretations, BE provides essentially the same information as bicarbonate. The major advantage of BE is that its normal range is really easy to remember.
Apr 11, 2018 · Depending on the algorithm used, standard base excess is calculated as 30 to 50 g per liter, which is essentially the estimated hemoglobin concentration in the extracellular fluid (one...

Summary. The base excess value (BE, mmol/L), not standard base excess (SBE), correctly calculated including pH, pCO2 (mmHg), sO2 (%) and cHb (g/dl) is a diagnostic tool for several in vivo events, e.g., mortality after multiple trauma or shock, acidosis, bleeding, clotting, artificial ventilation.
