What technique should a lifeguard use when rescuing a passive drowning person submerged in shallow water?

When rescuing a passive drowning person submerged in shallow water, the appropriate technique is to quickly swim or walk to their side. This method is crucial for several reasons. First, a passive drowning victim is unable to assist in their own rescue, which means the lifeguard needs to reach them as swiftly and efficiently as possible to prevent further submersion and reduce the risk of drowning.

Approaching the victim directly allows the lifeguard to assess the situation and provide immediate assistance, including supporting the victim's body to keep their head above water. Engaging the victim in this way minimizes the time they are submerged, which is vital since any delay increases the risk of hypoxia and other complications.

Using a flip turn is not appropriate in this scenario, as it is a technique typically used for improving efficiency while swimming, rather than for effective rescue operations. Throwing a flotation device from a distance may be beneficial in certain circumstances, but with a passive victim, getting to them quickly is essential for their safety. Lastly, while teamwork and calling for assistance are important in many rescue scenarios, immediate action should be taken for a passive victim to prevent a potential drowning event.
