I was fresh out of nursing school in the early 1990s, and working night shift in I C U... we got an elderly gentleman admitted, history of cardiac arrest, diagnosis chest pain rule out m.i....he hadn't eaten for 3 days and he asked for a bologna sandwich. He had eaten about half when he got choked and we began trying to dislodge the food... the admitting doctor walks in and looks at the monitor which is giggling crazily and says "witnessed v fib... get ready to shock..." i reached into the patients mouth mouth and removed a glob of food and flung it to the floor... "No, witnessed choking," as the patient then sits up coughing and says "Wow! Some bologna sandwich... Thanks!" the doctor looks at me incredulously and says, "You let him eat?"
