”This is the first time in the world that a research group can report results from a study where drones flew defibrillators to location of real-life alerts of suspected cardiac arrest,” says lead researcher Andreas Claesson, associate professor at the Center for Resuscitation Science at the Department of Clinical Science and Education, Södersjukhuset, Karolinska Institutet.
When a person suffers sudden cardiac arrest, every minute counts. Currently, as few as one in 10 people survives an out-of-hospital cardiac arrest. However, with early CPR and a shock from an automated external defibrillator (AED), the chances of survival could reach 50-70 percent. To get there, help needs to arrive faster. Reports from the emergency medical services of out-of-hospital cardiac arrest (OHCA) in Sweden show that in 2019 the median response time from alert to ambulance arrival in cases of cardiac arrest was 11 minutes.
In an effort to reach out-of-hospital cardiac arrest victims earlier, researchers at Karolinska Institutet, together with the national emergency operator SOS Alarm, Region Västra Götaland and drone operator Everdrone AB, explored using drones to quickly dispatch defibrillators in parallel with ambulances. The study, which was carried out in the summer of 2020 in the cities of Gothenburg and Kungälv in western Sweden, describes an integrated method where emergency operators, drone pilots and air traffic control worked together to facilitate the dual response.
