What action should be taken if a passenger collapses in the cabin?

The appropriate action when a passenger collapses in the cabin is to check responsiveness and begin CPR if the passenger is unresponsive. This response is critical because assessing the passenger's condition right away determines the urgency and type of care needed. If the individual is unresponsive and not breathing normally, immediate cardiopulmonary resuscitation (CPR) can be lifesaving, ensuring that blood continues to circulate and vital organs receive oxygen while awaiting professional medical assistance.

This approach emphasizes the importance of being proactive in emergency situations, prioritizing the passenger's life over other actions. It ensures that the situation is assessed properly and that immediate, effective measures are taken to sustain the passenger's life. Calling for medical assistance promptly can be important as well, but it should not come at the expense of assessing the passenger’s condition and providing immediate aid if needed.
