Ambulances are so 2016. After a cardiac arrest, the fastest way to send help is on a flying drone

The best medicine for a person who goes into sudden cardiac arrest is an electric shock. That jolt temporarily stops the heart, along with its rapid or erratic beat. When the heart starts itself up again, it can revert to its normal rhythm and resume pumping blood to the brain and the rest of the body. ... The sooner this happens, the better. When a patient is shocked within one minute of collapse, the chance of survival is nearly 90%. But if it takes 10 minutes to administer a shock, the odds or survival fall below 5%.
If a victim is are lucky, he’ll collapse in a mall, airport, school or other public venue that’s outfitted with an automated external defibrillator, or AED. These user-friendly machines can assess the cause of cardiac arrest, determine whether a shock is appropriate and deliver it if necessary. ... But if a victims is unlucky, he’ll have to wait for an AED to come to him. Usually, this means calling for an ambulance. But in the not-too-distant future, the ambulance could be replaced by a flying drone.
If that sounds ridiculously futuristic, head over to the Karolinska Institute in Stockholm, Sweden. That’s where a team of doctors and nurses built a bright yellow drone capable of delivering an AED to a patient in need. ... The drone in question weighs about 12.5 pounds and uses eight rotors to achieve speeds of up to 47 miles per hour. Once a pilot programs its route and destination, the drone uses a GPS system, autopilot software and a high-definition camera to get there. Fluorescent paint and LED lights help make it easy for people to find. ... Members of the research team had previously used geographic information system data to estimate whether there would be any advantage to putting AEDs on drones. Their models suggested that a drone would arrive faster than an ambulance 93% of the time, saving patients an average of 19 minutes.....
Now they’ve gone a step further and dispatched an actual drone from a fire station about 45 minutes north of Stockholm to 18 locations where people suffered actual cardiac arrests away from a hospital between 2006 and 2014. The times for the test flights were compared with the ambulance times recorded in the Swedish Registry for Cardiopulmonary Resuscitation. ... As predicted, the drones beat the ambulances handily, according to a report published Tuesday in the Journal of the American Medical Assn. In all 18 cases, the drone arrived more quickly than the ambulance had.
