What ventilatory change should be made if a patient is hypercapnic?

• A. Decrease tidal volume
• B. Increase respiratory rate
• C. Increase minute ventilation
• D. Reduce overall pressure

Answer: (C)

When a patient is hypercapnic, this indicates an elevated level of carbon dioxide in the blood, typically due to inadequate ventilation. The correct response to address hypercapnia is to increase minute ventilation. Increasing minute ventilation allows for a greater exchange of gases, specifically enhancing the elimination of carbon dioxide. This can be achieved by either increasing the tidal volume, the respiratory rate, or a combination of both. The goal is to improve the patient’s ability to ventilate effectively, thereby reducing hypercapnia and restoring normal gas exchange. Choosing to reduce tidal volume or overall pressure would not adequately address the patient's need for improved ventilation, as these actions would likely lead to even less effective removal of carbon dioxide. Increasing the respiratory rate is a possible strategy for accomplishing the goal of increasing minute ventilation, but it's important to specifically note that increasing minute ventilation provides a more comprehensive approach to managing the concern of hypercapnia, as it emphasizes the overall effectiveness of ventilation rather than a single change.
