A guy arrives in the emergency room after being resuscitated, having suffered a cardiac arrest while walking down the street. The doctor can't even visit him and he goes into cardiac arrest again. You have to resuscitate him with the defibrillator, but the shocks cause asystole. The compressions start strong, until they are no longer enough. The Ambu cannot get air into the lungs so a cannula is placed in the mouth. He is stripped completely naked and, after more CPR cycles, the doctor to intubate him. Resuscitation continues, the CPR board is placed under his back and the compressions continue faster and deeper. Eventually, after the last defibrillation, his heart starts beating again, but it remains uncultivated.
