Drone sent defibrillator test found to save 17 minutes of life-saving time

OFweekRobotOnline rescue of cardiac arrest patients is undoubtedly a race against time. Swedish researchers have tested and found that drones can deliver automated external defibrillators faster than ambulances, saving 17 minutes of life-saving time.

Researchers at the Caroline School of Medicine, Sweden’s largest medical school and medical research center, conducted 18 first-aid simulation tests of a drone-delivered cardiac defibrillator. The defibrillator weighs less than 2 pounds (0.9 kg) and includes electronic voice instructions for use. The launch point for the drone was at a fire station, and the test radius was 6.2 miles (10 kilometers).

The drone took an average of 5 minutes and 21 seconds to arrive at the location of the patient’s cardiac arrest, compared with an average of 22 minutes for the emergency vehicle. The 16 minutes and 39 seconds saved “could have important clinical implications,” the researchers said.

The research team analyzed data on cardiac arrest cases in towns near the capital Stockholm before testing. These towns do not have sufficient emergency medical resources for summer vacation tourists, the response time of ambulances is about 30 minutes, and the probability of survival is zero.

The research report was published in the Journal of the American Medical Association on the 13th.

Report author Andrea Klasson, a researcher at the Center for Resuscitation Sciences at the Caroline School of Medicine, said the study shows that in the future, drones can be used to speed up the speed of medical emergency placement. He plans to put the defibrillators delivered by drones into use in follow-up research. However, this requires further flight testing, technical research and development, and requires the participation and evaluation of the emergency center and aviation management department.

Cardiac arrest kills more than 6 million people worldwide each year and is one of the leading causes of death, the Associated Press reported. According to the American Heart Association, more than 350,000 people in the United States experienced cardiac arrest in non-medical settings last year. If left untreated, patients can die within minutes. The ideal means of rescue are CPR and the use of a defibrillator.

Clyde Yancey, former president of the American Heart Association, said that “90% of people who fall outside the hospital[from cardiac arrest]will not survive” and the results of the drone delivery of defibrillators are “very remarkable” .
