Why is it critical for lifeguards to know basic CPR?

Knowing basic CPR is critical for lifeguards because it enables them to provide lifesaving resuscitation during emergencies. In situations where a swimmer experiences cardiac arrest or near-drowning, immediate action can be the difference between life and death. CPR helps circulate blood and maintain vital oxygen flow to the brain and other organs until advanced medical help arrives. Lifeguards often encounter individuals who may require this life-saving technique, making it essential for them to be trained and confident in performing CPR to effectively respond to such emergencies.

Other options, while related to the overall role of a lifeguard, do not emphasize the immediate and lifesaving nature of CPR training in emergency scenarios. Being able to deliver effective CPR not only saves lives but also reinforces the lifeguard's responsibility to ensure the safety of all patrons in the swimming area.
