Which of the following is NOT part of the adult chain of survival?

The adult chain of survival consists of several critical components that work together to maximize the chances of survival following cardiac arrest. These components include early recognition of cardiac arrest and activation of emergency medical services (EMS), early cardiopulmonary resuscitation (CPR), rapid defibrillation if indicated, and post-cardiac arrest care. Each of these steps is essential for increasing survival rates.

Immediate first aid, while important in many emergency situations, is not specifically recognized as a distinct step in the adult chain of survival. The focus of the chain of survival is on the responses that specifically address cardiac events. Immediate first aid may involve actions taken for other types of injuries or emergencies but does not encompass the critical early interventions required for cardiac arrest scenarios.

Understanding this distinction helps clarify why immediate first aid is not categorized as a part of the adult chain of survival, highlighting the importance of each component in the context of cardiac emergencies.
