Jeepers...I don't know what she is looking for...but we went over this once. Here is what I had
Brain death - is diagnosed, when 3 EEG's are done and there is no brain activity
Clinical death - is when respirations and electrical activity in the heart has stoped. (unless, your looking at PEA) Then I think the MD is envolved. Not to mention, there maybe quidelines, r/t drowining, hypothermia, time down, when CPR was started, how long CPR has been in progress, etc. I mean brain death occurs in 8 minutes with out oxygen. But, I never knew to be a definite answer.
However, hospice, esp. in the field may be different. Now your dealing with terminal ill, DNR, comfort care....
I don't know, be interesting to see if there is a def. answer.
I'm assuming the same is true...no respirations, no pulse.~
Sorry couldn't be more useful
