"Web•Excess production of acid or decreased excretion of acid The anion gap is a useful calculation in assessing metabolic acidosis. Anion gap = [Na+] – ([Cl-] + [HCO 3-]) Loss of buffer has no effect on anion gap. Accumulation of organic acid (e.g., lactic acid) causes an increase in anion gap. Normal anion gap: <15 mEq/L Increased anion gap: " - Increased base excess

WebA "base deficit" of 10 means that 10 mEqu/L (mmol/L) of buffer has been used up to neutralize metabolic acids (like lactic acid). Another way to say the same thing would be the "base excess is minus 10." More negative values of base excess may indicate: Lactic acidosis. Ketoacidosis . Ingestion of acids . Cardiopulmonary collapse . Shock WebBase excess (BE) is derived from the whole blood buffer curve developed by Siggaard-Anderson and is defined as the amount of acid or base necessary to titrate a 1 liter of blood to a pH of 7.4 if PCO 2 is held constant at 40 mmHg. 21,22 Because PCO 2 is held constant, ...
