What is considered a normal base deficit/excess range?

The normal base deficit/excess range is typically considered to be from -2 to +2 mEq/L. This range indicates the amount of metabolic acid present in the body and how well the body can regulate its acid-base balance. A value of 0 indicates a neutral balance. Therefore, a range of -2 to +2 signifies that minor deviations from normal are within acceptable limits and do not indicate significant metabolic disturbances.

Base excess refers to the amount of excess or insufficient level of bicarbonate in the system, while base deficit, conversely, indicates how much acid is present. When values fall outside of this range, it can indicate metabolic acidosis or alkalosis, prompting further assessment and intervention.

Values falling outside of this range suggest more profound imbalances and may be clinically relevant, requiring further investigation. Understanding this normal range helps clinicians assess patient conditions accurately and make informed critical care decisions.
