What is considered the normal range for HCO3 in a healthy adult?

• A. 20 - 22 mmHg
• B. 22 - 26 mmHg
• C. 26 - 30 mmHg
• D. 30 - 34 mmHg

Answer: (B)

The normal range for bicarbonate (HCO3) in a healthy adult is 22 to 26 mmHg. Bicarbonate is an important buffer in the body that helps maintain acid-base balance. It is primarily produced by the kidneys and plays a critical role in maintaining the pH of blood and other fluids. Values below 22 mmHg may indicate acidosis, a condition where there is too much acid in the body or not enough bicarbonate, while values above 26 mmHg may suggest alkalosis, which is the opposite condition where there is too much bicarbonate or insufficient acid. Understanding this normal range is vital for healthcare professionals, as it assists in diagnosing various metabolic conditions, managing patients with respiratory or metabolic disorders, and assessing acid-base status effectively.
