What is the expected duration of supplemental oxygen usage?

• A. The passenger must discard the POC immediately
• B. The passenger will remain on supplemental oxygen until landing or POC resumes function
• C. The oxygen is only for takeoff
• D. The oxygen supply is unlimited

Answer: (B)

During a flight, if supplemental oxygen is prescribed, you continue using it for the entire trip—until landing or until the portable oxygen concentrator resumes operation after a fault. The reason is that cabin altitude reduces the amount of oxygen available to the body, so ongoing therapy prevents hypoxia throughout the flight, not just during takeoff. The idea that oxygen is only needed for takeoff is not correct, and oxygen supplies are not unlimited—the device and any backup sources have finite capacity and are managed by the airline and your medical needs.
