The formula for base deficit is as follows: Base excess = 0.02786 X pCO2 X 10^(pH - 6.1) + 13.77 X pH - 124.58
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.
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: B.E. = 0.9287 (HCO 3 - 24.4 + 14.83 (pH - 7.4)) or. B.E. = 0.9287 * HCO 3 + 13.77 * pH - 124.58.
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.
1.pCO₂. 2.pH. About. 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...
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.
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
