简要总结
Time to defibrillation is the most important predictor of survival in cardiac arrest. Traditional emergency medical system response is often to slow. The aim of this study is to investigate the feasibility of drone systems that delivers Automated External Defibrillators (AED) to the scene of suspected Out-of-Hospital Cardiac Arrests (OHCA).
This study will test the feasibility of real-life flights with drones carrying automated external defibrillators (AEDs) to out-of-hospital cardiac arrest (OHCA) as a complement to standard care i.e EMS
详细描述
We will test the feasibility of dispatching an out of sight AED-drone system to real-life OHCA in parallel with standard EMS dispatch. The study period is 5 months between May to September 2020. The study area will be covered by three individual drone systems covering some 80,000 inhabitants within the controlled airspace of Säve airport in Göteborg Sweden. Each drone system will have a flight range of six km.
The first month of the study period will be used as run-in period and the drone systems are dispatched for beyond visual line of sight (BVLOS) flights in a simulated fashion and optimized to decrease delays and to log pre-specified system variables, adherence to protocol, time delays, technological functionality, weather conditions, conflict in the airspace.
During the following 4 months June-September 2020, drones will dispatched to real-life suspected OHCA during daytime 08:00-22:00.
An EMS communication radio-unit is placed at the drone control center. In case of a suspected OHCA in the service area and will be alerted by the dispatch centre (SOS alarm) when a suspected OHCA is recognized during the 112-call.
- The dispatcher identifies a cardiac arrest in the service areas
- A pilot (from Everdrone) immediately initiates deployment protocol for the drone.
- Parallel communication is made with the air traffic control (ATC) centre in order to grant permit to deploy the drone with regards to the current weather and aviation situation.
- The drone then flies to the coordinates of the OHCA and delivers an AED at the scene using a winch system
- The AED may be attached to the patient by the bystander on scene

结局指标
主要结局
Proportion of suspected OHCA cases (%) where the AED-drone was dispatched and accurately completed mission.
时间窗: Up to 4 months
All cases of OHCA within the three service areas where the dispatch centre alerts the drone-operator and the drone takes-off. Accurate completion of mission equals deliver an AED onsite on the ground within 50 meters from OHCA location. AEDs shall be accessible to the bystander through T-CPR instructions given by the dispatcher.
次要结局
- Proportion of suspected OHCA with AED-drone arrival prior to ambulance(Up to 4 months)
- Proportion/numbers of attached drone delivered AEDs prior the arrival of EMS (%).(Up to 4 months)
- Time difference of drone arrival as compared to ambulance(Up to 4 months)
