What is the correct way to check for responsiveness in a casualty?

The appropriate method for checking responsiveness in a casualty involves gently shaking them and verbally prompting them by asking, "Are you okay?" This technique is recommended because it balances the need to elicit a reaction without causing potential harm or additional distress to the individual. The gentle approach provides a way to check the level of consciousness and awareness without being overly forceful, which might cause injury or exacerbate any existing conditions the casualty may have.

This method is effective in determining if the person is responsive or in need of further medical intervention. The gentle shake is less likely to provoke a negative physical response and allows for the possibility of a clear verbal response.

Other methods, such as tapping forcefully or shaking aggressively, can lead to potential injury or create a panic response in the casualty. Waving a hand in front of their face, while it might attract attention, does not provide a direct way to assess responsiveness and can be ambiguous in its effectiveness. Making loud calls while aggressively shaking could further distress the individual and does not offer a compassionate approach to checking their condition.
