What is the first step to provide 1-rescuer adult CPR?

The first step to provide 1-rescuer adult CPR is to call for emergency assistance and get an AED if available. This is crucial because ensuring that professional help is on the way and retrieving an Automated External Defibrillator (AED) can significantly improve the chances of survival for the victim. The sooner emergency services are alerted, the quicker advanced medical intervention can occur, which is vital in a cardiac arrest situation.

By obtaining the AED early in the process, the rescuer is also preparing to use this life-saving device to administer shocks if it’s indicated, thus enhancing the effectiveness of the response. This step establishes a foundation for all subsequent actions, including providing chest compressions and rescue breaths, which are important components of resuscitation once it is confirmed that the person is unresponsive and not breathing.
