AED-optimized dispatcher CPR instructions to reduce pauses during single-rescuer cardiac arrest response
Effect of AED-optimized Telephone-assisted CPR Instructions on No-flow Time and Chest Compression Fraction in a Single-rescuer Cardiac Arrest Scenario - a Randomized-controlled Simulation Study
This trial will test whether dispatcher instructions modified for AED use help single rescuers cut down pauses and keep chest compressions going longer during out-of-hospital cardiac arrest.

What this trial studies
This is a prospective, randomized, controlled simulation trial comparing standard telephone-assisted CPR (T-CPR) instructions to AED-optimized T-CPR instructions in single-rescuer scenarios. Adult volunteers (aged ≥16), including laypeople and healthcare professionals, are randomized to follow one set of dispatcher instructions while performing a simulated out-of-hospital cardiac arrest with an AED. Key outcomes measured are no-flow time (total time without chest compressions) and chest compression fraction (proportion of time compressions are performed). The study is run at the University of Pécs using standardized manikin scenarios and objective timing/recording of compressions and AED interactions.
Who should consider this trial
Good fit: Ideal participants are volunteers aged 16 or older who can physically perform CPR and are willing to take part in an in-person simulated single-rescuer scenario.
Not a fit: People who cannot safely perform physical CPR (for example due to pregnancy, cardiopulmonary or musculoskeletal conditions, or physical/psychological disabilities) would not be eligible and would not benefit from participating.
Why it matters
Potential benefit: If successful, dispatch centers could adopt AED-tailored instructions that reduce interruptions and increase time spent doing chest compressions, which may improve survival after out-of-hospital cardiac arrest.
How similar studies have performed: Telephone-assisted CPR and AED use independently have shown benefits for bystander intervention and survival, but randomized simulation data specifically testing AED-optimized dispatcher instructions for single rescuers are limited.
