One of the most depressing ambulance calls to get was when someone is clearly dead and has been for hours.  Upon entering the house the love ones are looking for you to provide a miracle and once you asses the patient it becomes clear that nothing can be done.  Now you have to go face the family and say I’m sorry, there’s nothing we can do.  I had one new widow praying hard on her rosary beads for just such a miracle that was never coming.  You’d like to revive their loved ones, but it just isn’t in the realm of possibility.
