What is the primary sequence of actions known as the chain of survival?

The primary sequence of actions known as the chain of survival emphasizes critical steps to improve the chances of survival in cases of cardiac arrest. The correct answer reflects a structured approach starting with early recognition of cardiac arrest, which is crucial because timely identification allows for rapid intervention. Following that, initiating early cardiopulmonary resuscitation (CPR) is essential as it helps maintain blood flow to vital organs until more advanced medical help arrives.

The next step, early defibrillation, is vital for restoring a normal heart rhythm in cases of shockable rhythms like ventricular fibrillation. This is often the most time-sensitive action, as the chances of survival decrease significantly with each passing minute without defibrillation. Lastly, post-resuscitation care is necessary to ensure that patients receive appropriate treatment after stabilization, focusing on optimizing outcomes and addressing potential complications.

This sequence is designed to maximize the effectiveness of each step and enhance survival rates, where the initial actions set the foundation for the following advanced interventions.
