What should be done first when dealing with an unconscious casualty?

When dealing with an unconscious casualty, the priority is to assess their condition for responsiveness. This initial step is crucial because it helps determine the level of consciousness and whether immediate lifesaving measures, such as CPR, are required. By checking for responsiveness, lifeguards can identify if the casualty is breathing or has a pulse, which informs the next steps in emergency response.

For example, a casualty who is unresponsive but breathing may need to be placed in the recovery position to maintain a clear airway, while an unresponsive and not breathing casualty would require immediate CPR. This assessment phase is foundational in ensuring that the proper actions are taken based on the casualty's condition, optimizing chances of survival and recovery.

In emergency situations, calling for help is also very important, but it should ideally occur after assessing the scene and the casualty, as this will dictate whether additional support is necessary. Swiftly placing someone in the recovery position may not be appropriate if they are not breathing or if there is a need for immediate resuscitation efforts.
