Web12 de set. de 2024 · When assessing the acid-base balance, most ABG analyzers measure the pH and PaCO2 directly. A derivative of the Hasselbach equation calculates the serum bicarbonate (HCO3) and base deficit or excess. This calculation frequently results in a discrepancy from the measured due to the blood CO2 unaccounted for by the equation. WebBE refers to a deviation of the buffer base (BB) from normal BB, and is the amount of base in fully oxygenated blood (which is zero at pH 7.4, the normal base value of the blood); it is equal to the amount of a strong acid or base needed to bring the pH in blood to 7.4 at a pCO2 of 40 mmHg—5.3 kPa at 37ºC.
Web30 de jan. de 2024 · What does a high base excess mean? A high base excess (> +2mmol/L) indicates that there is a higher than normal amount of HCO3– in the blood, which may be due to a primary metabolic alkalosis or a compensated respiratory acidosis. How do you interpret a base deficit? A base deficit indicates an excess of acid. WebSignificant metabolic acidosis (i.e. cord blood pH <7.0 or base excess <–16 mmol/L) is one of several entry requirements for application of this therapy [12].
