What is the best way to check if a person is unconscious?

The best way to check if a person is unconscious is to assess their responsiveness using verbal cues, such as asking, "Are you okay?" This method allows you to gauge whether the individual is aware of their surroundings. An unconscious person will not respond to questions or stimuli, indicating a lack of awareness.

While shaking their shoulders can be a physical way to stimulate response, it may not be the most appropriate first step, particularly if the person has sustained an injury. Moving someone before assessing their consciousness can be dangerous and potentially exacerbate any existing injuries. Checking their pulse may provide information about their physiological state, but it does not directly assess responsiveness, which is a primary indicator of unconsciousness. Therefore, asking a person if they are okay effectively allows the lifeguard to determine if they are conscious and responsive.
