Chapter 17 - Clinical Corner

You are an emergency medical technician and are sitting in a restaurant with your family. The place is crowded and you can’t help hearing the woman at the next table asking the waiter about whether there are peanuts in the dish she is ordering. The waiter assures her that there are none. You are about to finish and ask for your check when you notice the woman at the next table is choking and has a bluish tint to her skin. Immediately you sprint for your car and dig out an epinephrine syringe. The man sitting at the table with the woman is trying to lift her up saying that she needs the Heimlich maneuver. You push him out of the way and jab the needle into her thigh. Within minutes she is breathing more easily and her color is returning. The man is grateful but indignant that she would have been okay if he could have used the Heimlich maneuver.
