When rescuing a child from a pool, what is a crucial step a lifeguard must take?

When rescuing a child from a pool, securing the child with a flotation device is a crucial step for several reasons. First and foremost, flotation devices provide immediate buoyancy and support, helping to keep the child above water and preventing further drowning risk during the rescue. This can be particularly vital for a child who may be panicking or unable to swim.

Additionally, using a flotation device allows the lifeguard to maintain a safe distance from the child while performing the rescue, minimizing the risk of being pulled under by a distressed swimmer. It enhances control over the situation, enabling the rescuer to effectively guide the child back to safety.

In contrast, performing CPR immediately is not appropriate until the child is safely out of the water, and calling for backup, while important, should be done when it does not delay the rescue. Waiting for the child to resurface is not a proactive or safe option, as every second counts in rescue scenarios, especially in a pool environment where drowning can happen quickly.
