Which statement best describes non-invasive ventilation in oxygen management?

• A. Non-invasive ventilation may be used to support a patient when oxygen flow alone is not enough.
• B. Switch to room air and observe.
• C. Discontinue oxygen therapy.
• D. Use only bronchodilators.

Answer: (A)

Non-invasive ventilation provides positive airway pressure through a mask to support breathing when oxygen delivery alone isn’t enough. It helps improve both ventilation and oxygenation, reduces the work of breathing, and can prevent the need for intubation in suitable patients. So, saying that non-invasive ventilation may be used to support a patient when oxygen flow alone is not enough captures its role as an escalation of oxygen therapy. Switching to room air and observing would likely worsen hypoxemia if oxygen is needed. Discontinuing oxygen therapy removes essential support, which isn’t appropriate in this context. Relying on bronchodilators alone addresses airway constriction but does not provide the ventilatory support that NIV offers.
