What is the typical range for bicarbonate (HCO3) in meq/L?

The typical range for bicarbonate (HCO3) in milliequivalents per liter (meq/L) is indeed between 18.4 and 25.6. This range is crucial in assessing a patient’s acid-base balance, which can provide vital insights into various physiological conditions. Bicarbonate acts as a buffer in the blood, helping to maintain the body's pH within a narrow range, which is essential for normal cellular function.

Levels of bicarbonate can indicate whether the body is experiencing metabolic acidosis or alkalosis. If the bicarbonate levels fall below this range, it could signify metabolic acidosis, while levels above can indicate metabolic alkalosis. Understanding this range helps healthcare providers in diagnosing and managing conditions related to acid-base disturbances, making it a fundamental component of clinical practice, especially in fetal health when monitoring the well-being of both the fetus and the pregnant individual.
