While riding 3rd in a city somewhere in New York state, went to a cardiac arrest. Patient was an elderly woman, apneic on the floor. Being the first call of my first day, I was very excited at the prospect of getting an intubation on day 1. Anyway, tube in, pt asystolic on monitor, LP5, three rounds of drugs and an isuprel drip per local protocol. Well things weren't looking good, nice flat line on the monitor screen, too flat infact with all that good cpr taking place. While the medic on the radio was getting orders for field termination, I noticed the lifepak cable was attached to the pt, but the other end was stuffed in the pouch on the case, not inserted in the machine! :shock: Well, I reach over and plug it in, she's in a narrow complex tach at 200, great blood pressure, still apneic. We took her to the hospital, no one the wiser. Lessen: Always assess the patient.
