In the event of a medical emergency, what should a lifeguard do first?

In a medical emergency, a lifeguard's priority must be to assess the situation and determine the needs. This step is crucial because it allows the lifeguard to understand the nature of the emergency, identify any immediate dangers to both the victim and themselves, and prioritize the required response.

By conducting an assessment, the lifeguard can establish whether the victim is conscious, breathing, or in need of urgent medical attention. With this information, they can make informed decisions on whether to administer first aid or call for backup. Understanding the specific needs of the situation is essential for providing effective assistance and ensuring the safety of all involved. Proper assessment lays the groundwork for a structured response that can lead to the best outcomes in emergency care.

This foundational step is more significant than actions like calling for backup or recording details, which may be necessary but should occur after the initial assessment to ensure the immediate needs are addressed first.
