What is the first step in performing CPR?

The first step in performing CPR is to ensure the scene is safe and check for responsiveness. This crucial initial action involves assessing whether the environment poses any risks to both the rescuer and the person in need of help. After confirming safety, the rescuer should check the person's responsiveness by gently shaking their shoulders and asking if they are okay. This step is vital because it helps determine the next course of action. If the person is unresponsive, the rescuer can then proceed to call for help and initiate CPR if necessary.

This approach prioritizes safety before addressing medical emergencies. It ensures that the rescuer does not put themselves in danger, enabling them to provide effective help. Skipping this step could lead to complications and hinder the rescue effort.
