How many links in the chain of survival?

The chain of survival consists of five critical links: early recognition and activation of the emergency response system, early CPR (cardiopulmonary resuscitation), early defibrillation, advanced life support, and integrated post-cardiac arrest care. These steps are vital for improving the chances of survival and recovery for individuals experiencing cardiac arrest or other medical emergencies. Each link plays a crucial role in ensuring timely and effective intervention.
