During a code blue, what is the first step a rescuer should take?

Ensuring the area is safe is a fundamental first step during any emergency situation, including a code blue. This action is crucial because it protects both the rescuer and the patient from any potential dangers that might hinder the rescue effort. Without ensuring safety, there is a risk of further injury or complications from hazards such as falling objects, electrical issues, or crowded spaces.

In a code blue scenario, the environment should be assessed to determine if it is safe to proceed with resuscitation efforts. Once safety is confirmed, the rescuer can effectively call for additional help, check the patient's pulse, or begin chest compressions as necessary. Prioritizing safety sets the groundwork for a successful response and increases the likelihood of a positive outcome for the patient.
