Web3. Standard Base Excess – the Metabolic Component: If the Standard Base Excess (SBE) is acidic (a negative SBE), then the cause is metabolic. The exception, as above, is when the respiratory component is also acid when both are contributing to the acid pH. If the SBE is not like the pH, i.e., the SBE is alkaline, then the primary problem is ... WebThe base excess is the amount of strong acid or base required to titrate 1 liter of blood to pH 7.4 whilst pCO 2 is kept constant at 40 mmHg. It is calculated from the hematocrit, pH and pCO 2 . Base excess is affected by changes in non-volatile (or noncarbonic) acids and is thus an indication of the metabolic component of acid-base status.

WebA base deficit indicates an excess of acid. It refers to the amount of base needed to titrate a serum pH back to normal (healthy human-arterial blood pH varies between 7.35 and 7.45) when the contribution of respiratory factors is taken out of the equation. Base deficit is usually reported as a negative base excess. WebpH < 7.35 is an acidosis.
