Perhaps you are technically correct.
However, I think of resuscitations as having to do with folks who are still showing some signs of life within their bodies--they are not, per se, stone cold dead.
A good many, if not most, of these folks in this study were like Lazarus--stone cold dead for hours and even longer than a day in a number of cases.
Resuscitation seems a bit weak of a word for such 'bringing back to life' events.
I don't think we'd tend to call Lazarus resuscitated, would we?
I can see from the dictionary meaning that coming back from the dead would be considered a resurrection and not a resuscition.
I was viewing it from a strictly theological view.
