Mary is in the hospital after having a respiratory crisis and being resuscitated. She suddenly she has a second seizure, this time it seems more serious than the previous one. The monitor starts ringing and the doctor initiates the compressions while the nurse initiates the ambu stuffings. The compressions get deeper and deeper, until the defibrillator is needed, then Mary's chest is uncovered and she discharges several times, but with no response. Eventually her heart goes to asystole, so the girl is left completely naked and the doctor inserts the cannula while the nurse continues CPR. The heart then goes into fibrillation again and Mary is defibrillated again. After several rounds of CPR, defibrillation, and AMBU, the girl recovers. The heart rhythm remains irregular, however, until Mary goes into cardiac arrest again. CPR cycles resume, deeper and more numerous. After other cycles the girl recovers and the rhythm stabilizes. CPR, Defibrillator, Guedel Cannula, AMBU. Different camera angles. Totally naked!
