Drone delivery of AEDs to bystanders for out-of-hospital cardiac arrest

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

DAEDALUS is a proof-of-concept observational project testing drone delivery of automated external defibrillators (AEDs) to lay people responding to out-of-hospital cardiac arrest. The work includes hands-on simulation sessions where adult volunteers follow simulated emergency instructions, receive an AED by drone, and practise applying it to a training manikin, plus a second work package that recruits a purposefully sampled, diverse group for observation and feedback. Researchers will measure timing, safety, user ability to retrieve and apply the AED, and logistical or communication challenges from emergency call to AED use. The project is run at the University of Surrey in partnership with local ambulance and air ambulance services to reflect real-world operational workflows.

• Early double sequential defibrillation for cardiac arrest outside the hospital

  We test whether using two defibrillators in quick succession after the first failed shock helps adults with out‑of‑hospital cardiac arrest and a shockable rhythm survive more often than continuing standard single shocks.
