The presence and use of AEDs in public places such as airports, schools, and sports arenas have been shown to significantly improve survival rates in cases of out-of-hospital cardiac arrests (OHCA). Research indicates that when a bystander uses an AED while waiting for emergency medical services (EMS), the survival rate can increase from around 10% to nearly 40%. This highlights the critical role of public access to defibrillators in improving health outcomes.
