How should a lifeguard check for breathing in an unconscious victim?

To check for breathing in an unconscious victim effectively and efficiently, a lifeguard should utilize the technique of looking, listening, and feeling for a duration of no more than 10 seconds. This approach allows the lifeguard to quickly assess whether the individual is breathing or requires immediate intervention, such as CPR.

The method involves positioning the rescuer’s ear close to the victim’s mouth and nose while looking at the chest for any signs of movement and feeling for airflow. The emphasis on a short time frame is crucial because prolonged delays in assessing a victim's breathing can hinder timely lifesaving actions.

This rapid assessment ensures the lifeguard can make informed decisions quickly, which is vital in emergency situations where every second counts. By adhering to the recommended 10-second time limit, the lifeguard can initiate appropriate measures, such as calling for further assistance or starting CPR if necessary.
