That is a fantastic use of technology. This is interesting: "Now, during good CPR, this is probably going to be around 25 — if you keep this up in that 25 range, then there's circulation still going on. ... That's where you're going to get a positive outcome,". So essentially, if CPR is working, you don't need to die even if your heart and lungs aren't working on their own. CPR is doing their work well enough, for the moment anyway. If they keep at it all the way to the hospital, you may survive. Of course, if you'd seen Lindsey brought back in Abyss, you'd already know this is possible :-)
