Jun 12, 2016 · Base excess (BE) The base excess is another surrogate marker of metabolic acidosis or alkalosis : A high base excess (> +2mmol/L) indicates that there is a higher than normal amount of HCO 3 – in the blood, which may be due to a primary metabolic alkalosis or a compensated respiratory acidosis.

May 31, 2022 · Base excess (BE) was introduced by Siggaard-Andersen in 1960 as an answer to the forty-year-long quest for a reliable, stand-alone marker of metabolic acidosis/alkalosis, independent from co-existing respiratory derangements, and able to quantify the severity of the disorder . Previously, several parameters had been examined.
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.
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). e NBB is the BB experimentally obtained through equilibration and titration procedures aimed to achieve normal conditions of pH of 7.40 and PCO 2 of 40 mmHg.

Feb 15, 2021 · The base excess is the amount of strong acid that is required to return a patient's sample to a pH of 7.4, pCO₂ to 40mmHg and temperature to 37°. Normal Range. -2 to +2. Elevated Base Excess. A base excess greater than +2 suggests the presence of metabolic alkalosis. Causes of Elevated Base Excess.
