In Michigan can a dpoa invoke a dnr if the pt has signed a living will stating they want CPR?

Unable to answer this question. There is too much unknown information.

If ill - what was the diagnosis?

If injured - how severe were the injuries?

How long was the pt comatose before they were discovered?

Was the patient brain dead?

Would CPR have, in fact, assisted the individual?

Was the decision to cease, (or not begin) CPR a medical decision?
