UK Study Finds Drone‑Delivered Defibrillators Feasible but Flags On‑Scene Delays

Researchers now plan larger NHS trials following feasibility tests that revealed bystander challenges at the point of use.

In the study, researchers developed a system to deliver an AED suspended by a winch from a DJI M300 drone in response to a 999 call.

Overview

  • The NIHR‑funded University of Warwick team simulated 11 rural 999 calls, using a DJI M300 drone with a winch to lower an AED during live guidance from ambulance call handlers.
  • It took a mean 2.18 minutes from the emergency call to drone take‑off, with autonomous flights maintaining real‑time communications throughout.
  • After drone arrival, a further 4.35 minutes elapsed on average before a shock was delivered, indicating bystanders struggled to operate the AED quickly.
  • Authors say the system is promising for hard‑to‑reach areas but requires improved bystander support, refined call‑handler protocols, and operational evaluation before NHS use.
  • Ministers and partners voiced support for advancing the research, noting precedents in Denmark and Sweden and calling for funding to scale trials published in Resuscitation Plus.
