When is noninvasive ventilation indicated?

• A. In selected COPD exacerbation, cardiogenic pulmonary edema, or certain hypoxemic failures where NIV can improve ventilation without intubation.
• B. Only after intubation.
• C. For all patients with any hypoxemia.
• D. Never used in respiratory failure.

Answer: (B)

Noninvasive ventilation is used to support ventilation without an invasive airway in selected patients with acute respiratory failure, with the goal of avoiding endotracheal intubation. It is particularly helpful in COPD exacerbations with hypercapnic failure, where it helps remove CO2 and reduce the work of breathing; in cardiogenic pulmonary edema, where positive pressure can improve oxygenation and reduce workload on the heart; and in certain hypoxemic failures where the patient can cooperate, protect their airway, and NIV can improve ventilation and gas exchange enough to avoid intubation. Successful use depends on the patient being able to cooperate, maintaining airway protection, and having no contraindications such as facial trauma, inability to tolerate a mask, or severe instability. If these conditions aren’t met, invasive ventilation through intubation becomes necessary. This approach is about preventing intubation when possible, not performing NIV after already intubating.
