    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.

    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.

    Definition. Base excess is defined as the amount of strong acid that must be added to each liter of fully oxygenated blood to return the pH to 7.40 at a temperature of 37°C and a pCO 2 of 40 mmHg (5.3 kPa). [2] . A base deficit (i.e., a negative base excess) can be correspondingly defined by the amount of strong base that must be added.

    May 31, 2022 · HCO 3−, bicarbonate; A −, dissociated non-carbonic weak acids; Lac −, lactate; Ket −, ketoacids. Base excess can either be expressed for whole blood—BE (B), which does not consider the interaction of blood with the interstitial fluid, or for the entire extracellular fluid—BE (ecf), also called standard BE (SBE).

    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.
