This executive summary provides essential treatment algorithms for resuscitation of both children and adults, highlighting key changes since the 2010 guidelines. The European Resuscitation Council (ERC) Guidelines 2015 emphasize the importance of coordinated community responses, including emergency medical dispatchers, bystander CPR, and timely deployment of automated external defibrillators (AEDs) to improve survival from out-of-hospital cardiac arrest. Advanced life support guidelines focus on rapid response systems for deteriorating patients and prevention of in-hospital cardiac arrest. Special circumstances, such as asphyxia, special environments, and special patients, are addressed with specific recommendations. Post-resuscitation care, including urgent coronary catheterization and targeted temperature management, is a new emphasis. Pediatric life support guidelines cover basic life support, managing seriously ill children, and post-resuscitation care. First aid guidelines are included for the first time. The ethics of resuscitation and end-of-life decisions are discussed, along with the international consensus on cardiopulmonary resuscitation science. The guidelines are based on evidence from the International Liaison Committee on Resuscitation (ILCOR) and aim to improve survival rates and neurological outcomes.This executive summary provides essential treatment algorithms for resuscitation of both children and adults, highlighting key changes since the 2010 guidelines.
