A simulation study of drone delivery of Automated External Defibrillator (AED) in Out of Hospital Cardiac Arrest (OHCA) in the UK

Abstract

Background Drones are increasingly used in healthcare, and feasibility studies of deployment of Automated External Defibrillators (AED) in Out-of-hospital cardiac arrest (OHCA) have been conducted. Despite the potential contribution of drones to healthcare, regulatory barriers exist, including limits on flights beyond visual line-of-sight (BVLOS). The aim of this project was to deliver an AED BVLOS in Wales. Methods We developed of a Concept of Operations (CONOPS) to identify requirements, constraints, organisation and roles and responsibilities associated with deploying a drone to deliver an AED BVLOS. We equipped a Penguin B drone with satellite-enabled technology to enhance situational awareness and safety for the remote pilot. A BVLOS Operating Safety Case and three-week flight test programme was conducted with an AED attached directly to parachute for deployment to simulated OHCA. Results We completed six flights totalling 92km, 1:02.5 hours of flight time and four successful parachute payload drops. We conducted a successful end-to-end flight demonstration of an AED delivered via BVLOS by drone to a simulated OHCA and resuscitation by lay responder’s in a remote location; the final delivery of 4.5km was completed in 2:50 minutes. Conclusion We have delivered an AED by parachute, from fixed wing drone BVLOS in the UK in simulated OHCA. This project adds to the body of knowledge required for regulatory assurance on drone use BVLOS. Further research is needed before routine use of this technology.

The Role of Drones in Out-of-Hospital Cardiac Arrest: A Scoping Review

“…Four studies [ 20 , 21 , 22 , 23 ] were conducted in Canada, one [ 24 ] in France, two [ 25 , 26 ] in Germany, five [ 27 , 28 , 29 , 30 , 31 ] in Sweden, two [ 32 , 33 ] in the United Kingdom, one [ 34 ] in Ireland, one [ 35 ] in South Korea and 10 [ 18 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 ] in the United States. These locations varied in geographic scale from counties and towns to entire cities and covered a broad range of urban and rural settings.…”

Usage of Unmanned Aerial Vehicles in Medical Services: A Review

“…In Wales the project Concept of Operation was developed, to identify the requirements associated with deploying the drone to deliver ADS beyond visual line-of-sight (BVLOS). Studies showed successful transportation of an ADS by parachute payload drops, final delivery of 4.5 km was completed in 2:50 minutes [19].…”
