What is the normal base excess range for arterial and capillary blood?

The normal base excess range for both arterial and capillary blood is typically from -2 to +2 mEq/L. This range is important in assessing a patient's acid-base balance and can give insights into metabolic processes affecting the body, especially in critically ill neonates.

Base excess refers to the amount of excess or insufficient base in the blood, which helps in understanding metabolic acidosis or alkalosis. A base excess within this range indicates that the blood is in a relatively balanced state, not exhibiting significant disturbances that may point to conditions such as hypovolemia, renal issues, or respiratory problems.

Understanding this normal range is crucial for neonatal intensive care nursing as it allows healthcare providers to make informed decisions regarding interventions and treatments to stabilize the newborn's condition.
