What is the first step in performing CPR?

The first step in performing CPR is to ensure safety. This involves assessing the environment to make sure that it is safe for you to approach the victim and perform lifesaving measures. This step is crucial because entering a dangerous situation could put both the rescuer and the victim at further risk.

After confirming that it is safe to engage, the next steps would include checking for the victim's responsiveness and calling for help if needed. Understanding the prioritization of safety ensures that the rescuer can effectively and safely assist the victim without becoming a casualty themselves, which ensures that CPR can be performed without interruption or distraction.
