Last haunt I did we had a person have a major heart attack. I could tell just by looking at him because I used to be an EMT. He didn't want me to call an ambulance but I did anyway.. he survived with a triple bypass. Moral of the story... when I open back up in a few years I will do like major Vegas hotels do and invest in a defibrillator and train a few staff members. Beyond that I will just call an ambulance beyond first aid.
