alt Hacker NewsMost studies of hospital resuscitation survival puts it at about a 1/4. Plenty of people survive and have good neurological outcomes lots of people do not [0].
Outside of diagnostically defined cohort it’s a bit of a silly idea as you can attempt on anyone without respect to readily identified odds of success [1] so the what of CPR isn’t readily untangled from the who of it.
Out of hospital is a similar story but with less ability to triage and thus the same pattern in which the fact of CPR [2] is less informative than the underlying problem [3, old but the best study I know of would be interested if someone knows of an update to it given in hospital trend since].
