For a passenger requiring O2, how should the device be secured and worn?

• A. Secure the strap to the leg of the seat directly in front of the passenger, then place over the passenger's nose and mouth, and have them breathe deeply and normally
• B. Secure the strap to the armrest, then wear like a helmet
• C. Lay the device on the seat pocket
• D. Tie the strap around the waist

Answer: (A)

Securing an oxygen-delivery device so it stays in place and delivers air reliably is the key idea. Anchoring the strap to a fixed object, like the leg of the seat directly in front, keeps the unit steady even if the passenger shifts or the surroundings change. Placing the mask over the nose and mouth ensures the oxygen reaches the lungs, and instructing the person to breathe normally supports comfortable, effective delivery without forcing deep breaths. Other options fail because they don’t provide a stable attachment or proper delivery: attaching to the armrest, wearing it like a helmet, laying it in a seat pocket, or tying the strap around the waist would not keep the device secure or ensure the patient can unintentionally receive the oxygen properly.
