In the event of a cabin pressure issue, what is a flight attendant's immediate responsibility?

In the event of a cabin pressure issue, a flight attendant's immediate responsibility is to help passengers put on oxygen masks. This is crucial because a loss of cabin pressure can lead to a rapid decrease in oxygen levels, putting passengers at risk of hypoxia. The flight attendant must quickly ensure that every passenger is equipped with an oxygen mask to maintain safety and mitigate the physiological effects that accompany reduced cabin pressure.

Addressing passenger needs, such as helping them with luggage or ensuring they are seated quietly, becomes secondary since the priority is to provide adequate oxygen supply. Similarly, while preparing for landing might be part of the overall response to a cabin pressure issue, the immediate action focus must be on ensuring that passengers can breathe properly. Thus, helping passengers put on oxygen masks directly addresses the safety threat posed by a cabin pressure disturbance.
