What is the acceptable range for PaCO2 in arterial blood gas analysis?

The acceptable range for PaCO2 in arterial blood gas analysis is 35-45 mmHg. This range is crucial for assessing the respiratory component of acid-base balance in the body.

PaCO2, or partial pressure of carbon dioxide, reflects the adequacy of ventilation. A PaCO2 within this range indicates that the body is effectively removing carbon dioxide, helping to maintain a normal pH in the blood. Values lower than 35 mmHg often suggest hyperventilation, while values higher than 45 mmHg can indicate respiratory depression or hypoventilation. Therefore, understanding this range is vital for healthcare professionals when interpreting arterial blood gas results and managing patient ventilation and respiratory status.
