What oxygen delivery method is preferred for a patient with suspected facial trauma in flight?

• A. A tight-fitting mask delivering high-concentration oxygen (e.g., non-rebreather or similar), avoiding nasal cannula.
• B. Nasal cannula with low-flow oxygen.
• C. Simple face mask with low oxygen.
• D. Bag-valve mask with a poor seal.

Answer: (A)

In flight, a suspected facial trauma patient needs reliable, high-concentration oxygen delivery to offset the lower ambient oxygen and any airway compromise from injury. A tight-fitting mask that delivers high-concentration oxygen (such as a non-rebreather-style system) provides the best seal and maximizes FiO2, reducing the risk of hypoxia as cabin altitude changes or swelling occurs. Nasal cannula cannot reliably deliver high FiO2 and is prone to displacement or blockage by facial injuries. A simple face mask with low oxygen or a bag-valve mask with a poor seal won’t provide consistent, adequate oxygenation. So, the best choice is a tight-fitting mask delivering high-concentration oxygen.
