Life-saving drones tested to reach patients faster than ambulances

Researchers at the University of Warwick, in partnership with the Welsh Ambulance Services NHS Trust and drone company SkyBound, have developed and tested a drone delivery system to provide Automated External Defibrillators (AEDs) directly to cardiac arrest patients. In the UK, over 40,000 out-of-hospital cardiac arrests occur annually, with survival rates below 10%. Early use of CPR and AEDs can double survival chances, but bystanders often struggle to locate AEDs quickly, especially in remote or rural areas where ambulance response times are delayed. The tested system uses a DJI M300 drone to deliver an AED suspended by a winch in response to emergency calls, potentially reducing response times significantly. Emergency simulations in challenging rural locations demonstrated that drones could safely fly long distances, maintain communication with emergency services, and reach patients faster than ambulances. However, the study found that once the AED arrived, there was an average delay of over four minutes before a shock was delivered, partly due to bystanders
