How can lifeguards identify someone who may be experiencing a cardiac event?

Identifying someone who may be experiencing a cardiac event is crucial for lifeguards, as early recognition can save lives. The correct response highlights that an individual in distress may exhibit severe fatigue and have difficulty staying afloat. This is a key indicator because a cardiac event can lead to a sudden drop in strength and energy levels, making it challenging for the affected person to maintain their physical activity.

In the context of a swimming environment, someone who is usually capable of swimming may suddenly show signs of exhaustion, struggle to keep themselves above water, or exhibit irregular, labored movements. These symptoms can indicate that the body is not functioning properly, which is particularly true if the individual is not exhibiting usual behavior for a swimmer, such as maintaining a steady stroke or ease in the water.

By recognizing these signs, lifeguards can quickly assess the situation, approach the individual, and provide assistance as needed, including potential emergency protocols in case of a cardiac event.
