ABSTRACT
Survival rate for out-of-hospital cardiac arrest remains low across Europe. In the last decade, involving bystanders turned out to be one of the most important key factors in improving the outcome of out-of-hospital cardiac arrest. Beside recognizing cardiac arrest and initiate chest compressions, bystanders could be also involved in delivering early defibrillation. Although adult basic life support is a sequence of simple interventions that can be easily learnt even by schoolchildren, non-technical skills and emotional components can complicate real-life situations. This recognition combined with modern technology brings a new point of view in teaching and implementation. We review the latest practice guidelines and new advances in the education (including the importance of non-technical skills) of out-of-hospital adult basic life support, also considering the effects of COVID-19 pandemic. We briefly present the Szív City application developed to support the involvement of lay rescuers. Orv Hetil. 2023; 164(12): 443-448.
