What is the first step in performing CPR?

The first step in performing CPR is to assess the situation and check for responsiveness. This foundational action is crucial because it ensures the safety of both the rescuer and the victim before proceeding with any medical intervention. By assessing the situation, the rescuer determines if it is safe to approach the victim and checks whether the victim is conscious or unconscious.

In the absence of responsiveness, the rescuer then moves on to ensure that emergency services are alerted, either by calling for help or asking someone else to do so. This step is vital because immediate medical assistance is necessary in life-threatening situations.

Following the assessment, it's important to check for breathing. However, skipping the initial assessment could lead to performing CPR on someone who may only be unconscious or require different assistance. Therefore, starting with assessing responsiveness lays the groundwork for effectively responding to the emergency.
