During airway management, how should oxygen be delivered during the procedure?

• A. O2 15 L/min via nasal cannula during procedure
• B. No oxygen during procedure
• C. 100% oxygen via bag-valve mask
• D. After device placement

Answer: (A)

During airway management, keeping oxygen flowing even while you work to place the airway is key to preventing rapid desaturation. This approach, known as apneic oxygenation, uses a nasal cannula at 15 L/min to deliver oxygen continuously during the procedure. It provides a steady oxygen source to the lungs even when the patient isn’t breathing, helping extend the safe window to secure the airway. Preoxygenation with a bag-valve mask is still done before the attempt, but forcing 100% oxygen through the mask during the maneuver can get in the way of the procedure and isn’t as practical. Not giving oxygen during the procedure would risk hypoxia, and waiting until after device placement misses the critical period when the patient can desaturate quickly.
