Megan was driving home from work when she gets into an accident. She is stabilized on site and transported to the ER. She wears the cervical collar and the doctors immediately begin to examine the woman. Suddenly Megan goes into cardiac arrest and the rescuers begin CPR with chest compressions and AMBU bags. The EKG electrodes are placed on the chest and the bra is removed. CPR continues until a decision is made to defibrillate the woman's heart. The paddles are placed on her chest and the shocks shake Megan's body. There is no improvement and the CPR cycles continue unabated. After numerous attempts, the defibrillator still releases her shocks, but to no avail. The doctors continue to work on Megan's body, continuing chest compressions and AMBU bags. Eventually, after many cycles and many shocks, the woman recovers. CPR, Chest Compressions, Defibrillator, AMBU. Cervical Collar. Topless only.
