Jun 12, 2016 · Learn how to interpret arterial blood gas (ABG) results, including base excess, with a structured approach and clinical examples. Base excess is a measure of the acid-base status of the blood and can help identify the cause of metabolic acidosis or alkalosis.
Feb 15, 2021 · Learn how to interpret the base excess, an indicator of metabolic process independent of acid-base buffering system. Find out the causes and effects of elevated and reduced base excess, and how to calculate it from ABG results.
Oct 9, 2020 · Learn how to interpret arterial blood gases (ABGs) for medical students, OSCEs and MRCP. Base excess is the amount of strong acid that would need to be added or subtracted to return the pH to normal. See normal values, examples and clinical scenarios.
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.
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).
Aug 3, 2022 · Base excess is the amount of titratable acid needed to adjust blood pH to 7.4. It reflects the non-respiratory component of a pH disturbance. Learn how to measure and interpret base excess and other ABG parameters.
Interpretation. Base excess beyond the reference range indicates. metabolic alkalosis, or respiratory acidosis with renal compensation if too high (more than +2 mEq/L) metabolic acidosis, or respiratory alkalosis with renal compensation if too low (less than −2 mEq/L)
