Advanced Cardiac Life Support (ACLS)

NREMT PARAMEDIC

Definition

Algorithms for cardiac arrest (VF/pVT, PEA, asystole), bradycardia, tachycardia, and post-arrest care.

Clinical Significance

In prehospital care, understanding advanced cardiac life support (acls) can mean the difference between a positive patient outcome and a critical miss. A 65-year-old male presents with crushing substernal chest pain radiating to the left arm, diaphoresis, and nausea. 12-lead shows ST elevation in leads II, III, aVF (inferior MI).

Related pharmacology: amiodarone at 300mg IV/IO first dose, 150mg second dose, indicated for Refractory VF/pVT.

Historical Context

The modern EMS system in the United States traces to the 1966 "Accidental Death and Disability" white paper (NAS/NRC). Understanding of advanced cardiac life support (acls) has advanced significantly with evidence-based protocols. The NREMT, founded in 1970, standardized certification levels. Current ACLS and PALS guidelines are updated every 5 years by the AHA based on the International Liaison Committee on Resuscitation (ILCOR) evidence review.

Professional Standards

Professional standards for advanced cardiac life support (acls) are established by the relevant certification body and regulatory agencies. Certified professionals must demonstrate competency through examination and maintain credentials through continuing education. Scope of practice is defined by state law and facility policy. Never perform tasks outside your authorized scope.

Step-by-Step Procedure

Protocol steps for advanced cardiac life support (acls):

Stroke recognition: Cincinnati Prehospital Stroke Scale (facial droop, arm drift, speech) then last known well time then transport to stroke center
