Giving CPR only works when the person who's passed out is attractive. At least that's our motto. So for those times when you happen to see a troll passed out on the ground there's the Just-in-Time Support (JITS) device which lets you perform CPR without giving mouth. The device comes with a headrest, anesthesia mask, defibrillator pads, and a video screen that tells you what to do before jolting the victim's heart back to life. It's currently in prototype at the University of Utah. The chances of passing out next to someone carrying a JITS are slim, but it's a great concept nonetheless.
