What is the acceptable range for base excess/deficit in an arterial blood gas analysis?

In arterial blood gas analysis, base excess or deficit is a critical parameter that helps in assessing the metabolic component of acid-base status. The acceptable range for base excess is typically considered to be between -2 to +2 mEq/L. This range indicates that there may be slight deviations from normal metabolic function but are generally not significant enough to cause clinical concern.

A value within this range suggests that the body's buffering mechanisms are functioning adequately to maintain pH within normal limits, even in cases of minor metabolic disturbances. Values outside of this range can indicate more significant metabolic acidosis (negative values) or metabolic alkalosis (positive values), which may require further investigation and intervention.

Having a solid understanding of these ranges is crucial for flight paramedics, as it can inform treatment strategies and decisions in emergency care.
