The first step in the adult Chain of Survival during a cardiac emergency is the immediate activation of emergency medical services (EMS). This step is crucial because it ensures that professional medical assistance is on the way as quickly as possible. Prompt activation of EMS can facilitate timely intervention, such as advanced life support, medication administration, and rapid transport to a medical facility.

While performing CPR, defibrillation, and advanced life support are all essential steps in managing a cardiac emergency, they follow the initial activation of EMS. This priority emphasizes the need to get a higher level of care involved without delay, allowing trained responders to arrive with necessary equipment and medications that may be crucial for the patient's survival. Timely action at this first step can significantly improve the overall outcome for the patient experiencing a cardiac event.
