    Estimation. Base excess can be estimated from the bicarbonate concentration ( [HCO 3− ]) and pH by the equation: [4] 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: Interpretation. Base excess beyond the reference range indicates.

  2. 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.

  3. May 31, 2022 · BB = HCO−3 + A−. The BB considers the non-carbonic buffers and is theoretically CO 2 -independent. Unfortunately, a physiologic inter-subject variability due to different non-carbonic buffer concentrations was noticed [ 5 ].

  4. Nov 3, 2020 · standard base excess is dose of acid or alkali to return the ECF to normal pH (7.40) under standard conditions ( at 37C at a PCO2 of 40 mm Hg) this is the base excess calculated for anaemic blood (Hb = 50g/L)

  5. Base Excess & Calculated Bicarbonate. Calculate the serum bicarbonate from the serum pH and pCO 2. The calculations above are based on the Henderson-Hasselbalch equation: Replacing pK = 6.1, and [CO 2] = 0.03 * pCO 2, and removing the logarithms to get. HCO 3 = 0.03 * pCO 2 * 10 (pH - 6.1) In conjunction with the Siggaard-Anderson equation:

  6. Base excess of extracellular fluid is a quantity that reflects only the non-respiratory (metabolic) component of acid-base disturbances. It is the most used "non-respiratory" quantity for the diagnosis of acid-base disturbances and is calculated and presented by all blood gas analyzers produced today worldwide. Names, definitions and abbreviations.

  7. They defined base excess as the amount of strong acid (in mmol/L) that needs to be added in vitro to 1 liter of fully oxygenated blood in order to return the sample to standard (normal) conditions (pH 7.40, p CO 2 40 mmHg and temperature 37 °C.)
