ACLS Certification Mastery: Megacode, Drugs & Algorithms/The Chain of Survival and why sequence matters1 / 20

The Chain of Survival and why sequence matters
The Chain of Survival links early recognition, early CPR, early defibrillation, effective advanced life support, and integrated post-arrest care into one continuous process. This lesson walks through each link and explains why a break at any point — even a technically correct one performed too late — changes patient outcomes and changes how examiners score a megacode.
You'll also see how the 2020-era AHA guidelines frame high-quality CPR as the backbone every ACLS algorithm sits on top of, which is why compressions and airway management are graded before any drug is discussed.
