What is the normal range for CO2 levels in an ABG analysis?

The normal range for CO2 levels in an arterial blood gas (ABG) analysis is essential for assessing a patient's respiratory status and metabolic function. The correct range, 35-45 mmHg, indicates the balance of carbon dioxide in the bloodstream, which reflects the efficiency of ventilation and the metabolic processes in the body.

When carbon dioxide levels fall below 35 mmHg, it may suggest hyperventilation or respiratory alkalosis, while levels above 45 mmHg can indicate hypoventilation or respiratory acidosis. Maintaining CO2 within the normal range is crucial for the homeostasis of the body's acid-base balance and oxygenation status. Understanding this range helps healthcare professionals identify potential respiratory issues and adjust interventions accordingly to maintain optimal patient care.
