What is the first step in performing CPR?

The first step in performing CPR is to check responsiveness and breathing. This assessment is crucial because it helps determine whether the person is in need of CPR. By checking responsiveness, you can ascertain if the individual is conscious and aware. If the person does not respond and is not breathing or has abnormal breathing, this indicates a cardiac arrest, prompting the need for immediate action.

This step is fundamental because initiating CPR on someone who is still breathing could be counterproductive, and it's essential to ensure that the person requires help before proceeding with chest compressions or rescue breaths. This primary assessment lays the groundwork for the subsequent steps in the CPR process, allowing for an organized and effective response to the emergency situation.
