As pointed out, the save ratio is bad, however, it can work. As a former firefighter/EMT as one of my careers, I have had about 20 real CPR encounters with only 2 saves. One was an 18 month old little girl who drowned across the street from me and she made a full recovery. The other save was a 40 year old female with miscellaneous health problems with none of them being heart issues up until that time, and she made a full recovery. All the others were failures due prolonged heart issues for years. If done quickly, it can work, but don't bet the farm.

Pro (work from my study): 1) My study doesn't care if I show up naked, drunk, and with a hard-on. 2) I can surf for porno in between compilations and test runs. 3) Sex with co-workers is allowed there. 4) The only gas I have to use is the kind I pass. 5) Don't have to look at my ugly boss (and out-of-sight out-of-mind kind of thing). 6) Can use a hacked up eliza program to spin your boss in circles in chat while you finish that movie you were watching. Con: 1) No live good looking co-workers (you have to meet them somewhere) 2) If I keep showing up like #1 (Pro), typing with three thumbs is distracting even if you are only using one hand... 3) Don't don't have anyone around to watch their face when your +20 hit points stealth fart hits. 4) Don't get to open fire on the asshole that cuts you off on the freeway. 5) Don't get to flip off your boss when his back is turned (much more satisfying in person than to a computer screen) 6) Don't get to see Christy when she walks by in one of her too-small sweaters.
