Final answer:
Treatment for commotio cordis involves immediate defibrillation and CPR with high flow oxygen, while treatment for hangings prioritizes airway management and stabilization, with CPR and defibrillation as needed, followed by hospital transport.
Step-by-step explanation:
The treatment for commotio cordis (a sudden cardiac arrest due to a blunt, non-penetrating blow to the chest) typically involves immediate defibrillation if there is ventricular fibrillation or ventricular tachycardia, and CPR (cardiopulmonary resuscitation) with high flow oxygen should be initiated if the person is unresponsive and not breathing. For hangings, where asphyxiation and neck injuries are of concern, the focus is initially on airway management, ensuring the person can breathe, and stabilizing the cervical spine. The application of high-quality CPR may be necessary if the heart has stopped, and defibrillation may be used if required, although it is not the primary treatment. Immediate transport to a hospital is crucial for both scenarios.
