Understand the fundamentals of basic life support (BLS), including DRSABCD, CPR, airway assessment, and recognising life-threatening deterioration using current ANZCOR guidelines.

Learn about the Chain of Survival and the five critical links that improve outcomes following cardiac arrest. Understand how early recognition, CPR, defibrillation, advanced life support, and post-resuscitation care work together to maximise survival and recovery.

Understanding the reversible causes of cardiac arrest is an important component of advanced life support. This article explores the 4 Hs and 4 Ts, explaining how each condition can impair oxygenation, circulation, cardiac function, or electrical conduction.
