For a lot of sudden illness, and head for a few minutes is prime time for rescue, if this time do not receive proper care, patients will die easily. But for now, for a variety of reasons, even called the emergency distress call, ambulance may not be able to immediately arrived at the scene. For mental exhaustion, drowning, trauma and respiratory problems, in particular.

In order to give patients more time to rescue, reduce inappropriate spot treatment of accidental deaths caused by accidents, researchers from the University of Toronto intends to use drones for emergency medical assistance. Automated External Defibrillator (AED), cardiopulmonary resuscitation (CPR) auxiliary equipment such as life-saving system can be improved, for drone designed to be more compact to carry. According to relevant statistics, in EU countries, about 800,000 people suffer from sudden cardiac arrest each year, and can survive only 8%--this is an unsettling figure. Such a low survival rate, a large part of the reason is attributed to slow emergency services response times, because of brain death and permanent death occurred in the first 4-6 minutes.

Through the use of drones, timely assistance can greatly increase the number of patients. AED currently available using non-professional success rate is about 20%, if coupled with the drone of personalized instruction and communications help, success rate can increase to 90%. Extended by the drone of today's emergency infrastructure can undoubtedly help us save more lives.

In addition, compared with ordinary ambulances, and unmanned aerial vehicles rushed to the scene of the process does not need to consider the ground traffic and achieve faster – every minute of time, reduced patients ' chances of survival.

Large scale application, this emergency drones also faces many challenges, which is why the Government is still not so perfect unmanned aerial vehicle system. Netherlands air traffic law even forbids the use of autonomous drones, but in 2015, this provision has been amended. Boutilier, University of Toronto Professor, as Google and Amazon have in the delivery of the drones, continued to lobby Government departments can be expected soon related measures will be refined and improved. Until then, emergency drones will help us save many more precious lives.

对于很多突发疾病来说，发病的头几分钟是抢救的黄金时间，如果在这段时间内不能得到适当的护理，病人很容易就会因此丧命。然而目前来说，因为各种各样的原因，即便是拨打了紧急求救电话，救护车也不一定能立马赶到现场。对于心理衰竭、溺水、创伤以及各种呼吸问题而言，尤其如此。

为了给病人争取更多的抢救时间，减少因为不恰当的临场处理造成的意外死亡事故，来自多伦多大学的研究人员打算将无人机用于紧急医疗救助中。像自动体外除颤器（AED）、心肺复苏（CPR）辅助设备等救生系统能够经过改良，设计得更为紧凑供无人机携带。据相关数据统计，在欧盟国家中，每年大约有80万人患有心脏骤停，能够幸存下来的人只占8%——这是一个让人不安的数字。如此低的幸存率，很大一部分原因就要归咎于缓慢的急救服务反应时间，因为脑死亡和永久性死亡都发生在最开始的4到6分钟之内。

通过无人机的使用，得到及时救助的病人数量能够大大提升。目前掌握AED使用的非专业人士成功率约为20%，如果再加上无人机上的个性化指令和通信帮助，成功率能够提升到90%。通过无人机来扩展当今的应急基础设施，无疑能够帮助我们挽救更多的生命。

另外，和普通的救护车相比，无人机在奔赴现场的过程中不需要考虑地面的交通状况，因此达到的速度也更快——时间每过一分钟，病人生存下来的几率就减少一点。

要大规模投入应用，这种急救无人机还面临着很多挑战，其中就是政府目前依然不太完善的无人机监管体制。荷兰的空中交通法律甚至禁止使用自主无人机，不过这项规定在2015年也得到了修正。多伦多大学的Boutilier教授表示，随着谷歌和亚马逊已经在交付无人机，持续对政府部门进行游说，可以预计很快相关的措施能够得到完善和提高。到那时，急救无人机将会帮助我们挽救更多的宝贵生命。
