From Fox News:
Imagine this scenario. You are at home hanging out with your loved ones, enjoying a relaxing evening. Suddenly, a relative collapses on the floor, clutching his chest.
You call 911, but you know that every second counts. What if you had a device that could help you revive your relative before paramedics arrive? That’s the idea behind CellAED, a cell phone-sized personal defibrillator invented by a father who almost lost his wife to cardiac arrest.
