What condition must be met when a person is administered medical oxygen in flight?

When a person is administered medical oxygen in flight, it is crucial that they are seated to avoid blocking exits. This requirement is rooted in safety protocols to ensure that in case of an emergency, all passengers and crew can exit the aircraft quickly and safely. When an individual uses oxygen, especially in a medical context, they may require monitoring or assistance. By ensuring that the individual is seated, it helps maintain the integrity of the cabin environment and allows the crew to manage the situation without potential hindrances.

Maintaining clear access to exits is vital for overall passenger safety, which is why this condition is emphasized. Proper seating also allows the flight crew to keep an eye on the person receiving the oxygen, ensuring that any medical needs are adequately addressed while not compromising the safety of other passengers.
