Question: 1 / 400

What is the specified PaCO2 level for respiratory function?

30-40 mmHg

35-45 mmHg

The specified PaCO2 level for optimal respiratory function is indeed between 35-45 mmHg. This range is considered normal and reflects the body's ability to effectively exchange carbon dioxide (an indicator of how well the lungs are functioning). Maintaining a PaCO2 within this range is crucial for acid-base balance and effective respiratory status, as it indicates proper management of carbon dioxide produced by cellular metabolism and its removal during respiration.

When PaCO2 falls below 35 mmHg, it suggests hyperventilation, while levels above 45 mmHg indicate hypoventilation. Both conditions can lead to significant physiological issues. Therefore, understanding and maintaining the PaCO2 within the specified range is essential for ensuring effective respiratory function and overall patient health.
