Drones could deliver defibrillators faster to out-of-hospital cardiac arrest patients
Key points
- Out-of-hospital cardiac arrests have low survival rates.
- Rapid defibrillation improves survival chances.
- Fixed AED accessibility is limited in Greater Paris.
- Drones could expand defibrillator coverage with fewer devices.
The Challenge of Out-of-Hospital Cardiac Arrests
Over 30,000 out-of-hospital cardiac arrests occur annually in the UK, with fewer than one in ten survivors. Rapid access to defibrillation is critical, as each minute without treatment reduces survival chances by 10%.
Drone Delivery as a Solution
Researchers led by Matthieu Heidet and Hillary Minka investigated using drones to deliver defibrillators. Their study analyzed 28,349 cardiac arrest cases in the Greater Paris area between 2011 and 2024, excluding central Paris.
Limitations of Fixed Defibrillators
The study found that only 30% of cardiac arrest cases occurred within 500 meters of an existing fixed automated external defibrillator (AED). Achieving 100% coverage with fixed AEDs would require 1,712 additional devices.
Increased Coverage with Drones
Introducing drone bases significantly improved coverage. With 100 drone bases and 26 additional fixed AEDs, over 97% of cases would be covered. Using 200 drone bases and only four extra fixed AEDs would cover more than 99% of cases, demonstrating drones' potential to expand access to life-saving equipment.

Reporting from
A study in the Greater Paris area suggests drones could improve access to defibrillators for out-of-hospital cardiac arrests. Researchers found that using drones could significantly increase coverage compared to relying solely on fixed defibrillator locations, potentially improving survival rates.
