Robert is at home and suddenly starts to feel bad. He feels chest pain and breathlessness. When the pain becomes unbearable he sends a message and within a short time he has difficulty breathing. He definitely collapses and stays on the floor. When the rescuers enter, the boy no longer has a pulse and the resuscitation maneuvers must begin. CPR and AMBU bagging begin. After several cycles they also bring the defibrillator and uncover the boy's chest. After several shocks the heart does not start beating and they have to resume resuscitation. The compressions are deep and the shocks from the defibrillator follow one another. The heartbeat eventually returns and Robert recovers. Deep compressions, CPR, AMBU, DEFIB. Different camera angles.
