Drones may help save lives faster than ambulance
Out-of-hospital cardiac arrest has low survival, with reducing time to defibrillation as the most important factor for increasing survival.
For every minute that passes between a person collapsing due to cardiac arrest and defibrillation, the chances of survival decrease by 10 per cent, the study said.
In the study, published by
"Saving 16 minutes is likely to be clinically important. Nonetheless, further test flights, technological development, and evaluation of integration with dispatch centres and aviation administrators are needed," said
An eight-rotor drone was developed and certified by the
The drones were activated by a dispatcher and sent to a particular address with the defibrillator -- that are designed to give spoken instructions so that any bystander can use them, further reducing the response time.
The drones responded to 18 simulated cardiac arrests within a six-mile radius of their base, beating the ambulance every time with a median reduction in response time of 16:39 minutes.
