Which scenario is a typical indication for noninvasive ventilation in acute care?

• A. COPD exacerbation with hypercapnic respiratory failure
• B. Chronic stable asthma without symptoms
• C. Stable pneumonia with normal oxygenation
• D. Postoperative stable patient with adequate gas exchange

Answer: (A)

Noninvasive ventilation provides ventilatory support through a mask, delivering positive pressure to assist breathing. In acute care, it is typically indicated when there is acute hypercapnic respiratory failure, most often from a COPD exacerbation. The rising CO2 and resulting acidosis reflect insufficient ventilation, and adding pressure support helps move air in and out more effectively, reduces the work of breathing, and improves gas exchange quickly. This approach can often prevent the need for endotracheal intubation, as long as the patient can cooperate, protect the airway, and remain hemodynamically stable.

In the COPD-exacerbation scenario with hypercapnic respiratory failure, these benefits align with the patient’s immediate needs, making noninvasive ventilation the best initial choice.

The other scenarios don’t fit: chronic stable asthma without symptoms isn’t an acute ventilatory failure, stable pneumonia with normal oxygenation shows no hypoxemia or hypercapnia requiring NIV, and a postoperative stable patient with adequate gas exchange doesn’t need ventilatory support.
