What is the normal range for PaCO2 in a healthy individual?

• A. 25 - 35 mmHg
• B. 35 - 45 mmHg
• C. 45 - 55 mmHg
• D. 55 - 65 mmHg

Answer: (B)

The normal range for PaCO2, or arterial carbon dioxide pressure, in a healthy individual is 35 - 45 mmHg. This value is crucial for assessing a person's respiratory function and metabolic status. A PaCO2 level within this range indicates that the body's mechanism for exchanging oxygen and carbon dioxide is functioning properly. When interpreting PaCO2, values below 35 mmHg suggest hyperventilation, which can lead to respiratory alkalosis due to decreased carbon dioxide levels. Conversely, values above 45 mmHg indicate hypoventilation, leading to respiratory acidosis from an accumulation of carbon dioxide. Therefore, understanding the normal range is essential in clinical settings for diagnosing and managing respiratory conditions. This helps ensure that any deviations can be addressed swiftly to maintain effective respiratory function and overall homeostasis.
