What should a lifeguard do if they discover a swimmer is unresponsive?

When a lifeguard discovers a swimmer who is unresponsive, the appropriate action to take is to call for help and begin CPR if trained. This response is crucial because an unresponsive swimmer may be in a critical situation, possibly due to drowning or a medical emergency, that requires immediate intervention.

Initiating CPR promptly can be lifesaving, as it helps maintain blood flow and oxygenation to vital organs until professional medical assistance arrives. The training provided to lifeguards emphasizes the urgency of acting quickly in emergencies, underscoring that waiting or attempting less effective measures, such as monitoring the situation or trying to revive the individual with cold water, can significantly reduce the chance of survival.

Taking immediate action and calling for assistance ensures that emergency medical services are notified and on their way, while also providing the best chance for recovery through life-saving techniques such as CPR if the lifeguard is qualified to perform it.
