After the first responder says the scene is safe, what is the first step in performing CPR?

The first step in performing CPR after the first responder indicates that the scene is safe is to check for responsiveness. This is a critical initial action because it helps to determine whether the individual requires assistance and assesses their level of consciousness. If the person is unresponsive, it indicates that immediate medical attention is necessary, and CPR should begin.

Checking responsiveness typically involves gently shaking the person and shouting to see if they respond. This preliminary step not only confirms the need for CPR but also ensures that any potential dangers to the responder themselves or bystanders are assessed. It is essential to establish whether the person is conscious or unconscious, as this influences subsequent actions, such as calling for emergency services or starting the CPR protocol.

In a situation where immediate intervention is required, once responsiveness is checked and the individual is found unresponsive, the responder would then proceed to call for emergency services, followed by opening the airway, and finally beginning chest compressions if the person is not breathing. Each step is paramount in the chain of survival; however, the very first action upon ensuring the safety of the scene is indeed confirming responsiveness.
