What are the signs of drowning a rescuer should be vigilant for?

The signs of drowning that rescuers should be vigilant for include behavior that indicates distress or struggle in the water. Panic and splashing are key indicators, as individuals who are drowning often exhibit erratic movements in an attempt to stay afloat or signal for help. This behavior is a result of the victim's increased anxiety and lack of control, which are critical signs that the person is in danger and may require immediate assistance.

In contrast, floating without movement can sometimes indicate that the individual is unconscious or has already drowned, but it does not suggest active distress. Excessive noise from the victim could reference yelling or calling for help, but drowning individuals may not be able to make noise due to their struggle for air. Clear visibility of the victim typically suggests that they are not drowning, making this option less relevant in identifying drowning behavior. Therefore, focusing on the signs of panic and splashing is essential for rescuers to effectively determine when intervention is necessary.
