Public defibrillator usage is a critical component of the emergency response to sudden cardiac arrest, where an automated external defibrillator (AED) can significantly increase survival rates when used alongside basic life support (BLS) techniques such as cardiopulmonary resuscitation. According to systematic reviews, early intervention with CPR and AED use can improve survival by up to 70% compared to situations where action is delayed. This article explores the importance of public access defibrillation, proper training, and the development of community emergency response systems in the Australian context.
