When traveling, others say that the oxygen bag is flat. How to answer it?

1. If you find that the oxygen bag is flat during the trip, please don't worry first. This may be caused by airlines adjusting cabin pressure during the take-off and landing of aircraft.

2. If you encounter air leakage in the oxygen bag during the trip, please report it to the flight attendant immediately. They will check and take necessary measures to ensure the safety and health of passengers.

3. The rupture of the oxygen bag does not necessarily mean an emergency, but in order to ensure safety, please inform the crew as soon as possible so that they can evaluate and deal with the problem.
