Normal arterial PaCO2 range is?

Explanation:
The main idea here is understanding the normal arterial CO2 level that the lungs keep in balance with CO2 production. In healthy people, arterial PaCO2 is normally 35–45 mmHg. This range reflects the typical rate of CO2 removal by ventilation relative to the amount produced by metabolism. If you ventilate more (blow off more CO2), PaCO2 drops; if you ventilate less, PaCO2 rises. Values below 35 indicate hypocapnia from over-ventilation, while values above 45 indicate hypercapnia from under-ventilation. The other offered ranges (like 25–35, 45–60, or 10–20) would place you outside the normal ventilation balance. So, 35–45 mmHg is the normal arterial PaCO2 range.
