What is the first step when encountering an unconscious, non-breathing individual?

When encountering an unconscious, non-breathing individual, the first step is to call EMS (Emergency Medical Services) and get an Automated External Defibrillator (AED). This action is crucial because it ensures that professional help is on the way and that potentially life-saving equipment, such as the AED, can be utilized as soon as it becomes available.

In emergency situations, time is of the essence, especially in cases of cardiac arrest, where every minute counts. Calling for EMS alerts professional responders to the situation, allowing them to arrive and administer advanced medical care rapidly. Acquiring an AED is also vital, as it can provide defibrillation, a lifesaving intervention for someone in cardiac arrest.

The other options do not appropriately address the immediate needs of the individual. Attempting to wake them or providing water is not suitable, as it does not address the critical nature of their condition. Providing chest compressions is a necessary action but should occur only after emergency services have been notified. Without first ensuring that help is on the way, you may miss the opportunity to get necessary equipment and assistance in a timely manner.
