What this Trial Is About
Researchers are investigating how modified telephone-assisted cardiopulmonary resuscitation (T-CPR) instructions optimized for automated external defibrillator (AED) use affect no-flow time and chest compression fraction during single-rescuer cardiac arrest scenarios. Out-of-hospital cardiac arrest is a major cause of death worldwide, and survival depends on early CPR and defibrillation. This randomized controlled simulation study aims to improve dispatcher guidance to reduce interruptions and improve CPR quality. Participants are randomly assigned to one of two groups: one receives standard T-CPR instructions based on current guidelines, and the other receives enhanced AED-optimized T-CPR instructions. The enhanced instructions focus on minimizing pauses in chest compressions, reducing time to first compression, and optimizing AED use steps such as immediate activation upon retrieval and continuation of compressions during AED charging. The study follows European Resuscitation Council 2025 guidelines. During the study, participants perform dispatcher-assisted CPR simulations while researchers measure no-flow time, time to first chest compression, time to first shock, chest compression fraction, and peri-shock pauses. The study monitors performance during the procedure and collects data on interruptions and timing. The overall goal is to evaluate whether AED-optimized instructions improve CPR quality in single-rescuer situations. The study is sponsored by the University of Pecs and includes healthy volunteers aged 16 and older.
