When interpreting ABG results, what does a HCO3 of 24 mEq/L signify?

A bicarbonate (HCO3) level of 24 mEq/L is considered to fall within the normal range for blood pH and metabolic function, which typically lies between 22 to 28 mEq/L. This indicates that the bicarbonate concentration is not contributing to any significant acid-base disturbance.

In clinical contexts, bicarbonate is a key buffer in the body that helps to maintain pH balance. A normal HCO3 level suggests that metabolic processes are functioning well and the body is capable of adequately regulating its acid-base balance. Therefore, when evaluating ABG results, a HCO3 level of 24 mEq/L indicates that there is no metabolic acidosis or alkalosis affecting the patient at that moment.

This normal reading is critical when determining a patient’s overall acid-base status, as it assists healthcare professionals in diagnosing potential respiratory or metabolic conditions based on other accompanying ABG parameters.
