Please detail the times when CPR is inappropriate.
The only situations I know of are when a DNR is present.
and when death is obvious.
Otherwise how can you make a decision if it is appropriate or not?
I don’t know about any other situation, but I do know what happened with my mother. When she deteriorated to the point that it was more likely that CPR would do more damage than good, that is it would be likely to hasten death, the rav said to issue the DNR. I don’t remember the exact time frame, but it was several hours before she passed away.
The hospital had been asking about (pushing?) a DNR for several months as my mother was in-and-out of the hospital.
