Which of the following is the normal range for HCO3 in blood gas analysis?

The normal range for bicarbonate (HCO3) in blood gas analysis is between 22 and 26 mEq/L. This range indicates the concentration of bicarbonate in the blood, which plays a crucial role in maintaining the pH balance of the body. Bicarbonate acts as a buffer to neutralize acids, thus helping to keep the blood pH within the normal range of 7.35 to 7.45. Values below 22 mEq/L may suggest a metabolic acidosis, where there is an excess of acid or loss of bicarbonate in the body. In contrast, values above 26 mEq/L typically indicate metabolic alkalosis, where there is an excess of bicarbonate or loss of acid. Understanding the normal range for HCO3 is vital for diagnosing and managing various acid-base disorders in critical care settings.
