If a passenger is unconscious but breathing, what should be administered?

Administering oxygen with a Portable Oxygen Bottle (POB) is the appropriate response when a passenger is unconscious but breathing. This approach ensures that the individual receives supplemental oxygen, which can be crucial in maintaining adequate oxygenation, especially if there are concerns about their airway or potential respiratory distress. The immediate need is to stabilize the individual's condition and provide any support that can enhance their breathing capability.

The use of oxygen is essential in these situations because it can help to alleviate any potential hypoxia, which is a condition where the body or a region of the body is deprived of adequate oxygen supply. By administering oxygen, you are ensuring that the unconscious passenger is receiving necessary support while waiting for medical assistance or the situation to improve.

In this scenario, administering CPR is not appropriate because the passenger is breathing, and CPR is designed for cases where there is no breathing or heartbeat. Providing water is also not suitable, as it could pose a choking risk or further complicate the person's condition. While seeking medical assistance from nearby passengers can be beneficial, oxygen supplementation is a more immediate and direct intervention that addresses the passenger's urgent needs.
