After initiating the emergency response system, what is the next link in the Adult In-Hospital Cardiac Chain of Survival?

  1. Early high-quality CPR

  2. Rapid defibrillation

  3. Advanced life support

  4. Hospital admission

The correct answer is: Early high-quality CPR

In the Adult In-Hospital Cardiac Chain of Survival, the next critical step after initiating the emergency response system is high-quality CPR. This step is essential because it maintains blood flow to vital organs during cardiac arrest, increasing the chances of survival and favorable outcomes for the patient. High-quality CPR involves effective chest compressions that are both deep and fast, followed by ensuring proper ventilation. It is the immediate action that can buy time until advanced medical care arrives. When CPR is performed promptly after cardiac arrest, it helps to preserve the function of the brain and other vital organs by ensuring that oxygenated blood continues to circulate. Although rapid defibrillation, advanced life support, and eventual hospital admission are all important components of post-cardiac arrest care, they follow the need for immediate and effective CPR. Without initiating CPR right away, the victim's chances of survival decrease significantly, highlighting the crucial nature of this first response in the chain of survival.
