Off the top of my mind, I can think of two patients who I personally cared for in the days or weeks after CPR who had an outcome other than death or vegetative state. One patient walked out the door two weeks after admission. The other patient regained consciousness and was able to speak/communicate, but was bed bound, appeared to have sustained some degree of cognitive damage, and had to receive feeds through a gastric tube. She was in the hospital for about six months before being discharged to a nursing facility. That's the numerator. It's hard to quantify the denominator. 40 or 50 maybe? But that's a guess.
