What should be done for a casualty who is unconscious and breathing?

For a casualty who is unconscious yet still breathing, placing them in the recovery position is a critical and appropriate action. The recovery position helps to maintain an open airway, which is essential for ensuring that the person continues to breathe adequately. This positioning also provides a way for any fluids or vomit to drain out of the mouth, reducing the risk of choking or aspiration that could occur if the person were left lying on their back.

In contrast, administering oxygen may be beneficial, but it should only be done if the casualty is in a position where their airway can be effectively managed. Starting CPR is not warranted in this scenario because the casualty is breathing, indicating there is still a functional breathing mechanism. Monitoring closely without movement can be important, but it does not address the potential airway issues that can arise from an unconscious state. The recovery position is specifically designed to mitigate these risks while ensuring the casualty remains as safe and stable as possible.
