Bicarbonate is a crucial electrolyte closely monitored to assess acid-base balance in the body. It functions primarily as a buffer, helping to maintain the pH level of blood and other bodily fluids within a narrow range. The bicarbonate buffering system works by reacting with excess acids or bases to neutralize them, assisting in stabilizing the pH, which is essential for normal physiological functions.

The measurement of bicarbonate levels provides insights into the body's metabolic state. Elevated bicarbonate levels are often indicative of metabolic alkalosis, while decreased levels can point to metabolic acidosis. Therefore, monitoring bicarbonate is vital for understanding and managing conditions that affect acid-base balance, such as respiratory or metabolic disorders.

Understanding the role of bicarbonate in acid-base balance enables healthcare providers to identify and address potential imbalances effectively, supporting overall patient care.
