“Time is really of the essence here,” said Justin Boutilier, an assistant professor at the University of Wisconsin–Madison. “Survival from cardiac arrest decreases by between 7 to 15% for every minute that you go without treatment.”
Boutilier describes obstacles to emergency response —such as traffic or difficult-to-reach rural locations — as “the perfect storm.” He has been designing a prototype drone that takes off as soon as someone calls 911.
