Subtle signs of impending death.
I have had nurses call me to the hospital to see a patient because something is going on with the EKG and everytime they have seen it before the patient does very poorly. I will bet you that nurses could write the book on this subject but most hospitals no longer use nurses to monitor EKG's nor do the machines we use retain long intervals of rhythm strips. So, now that we got rid of the best hope (nurses and ao monitors) in favor of lower costs, we now are going to buy more expensive machines to duplicate the previous efforts.
Then we send them home on medicine they can't afford to continue to take as they have hit the doughnut hole and have not had a social security raise in several years. It gets discouraging.
