If you need to code heart stoppage, you should immediately call emergency services or 911 in your country for immediate medical assistance. They will provide you with instructions on how to perform cardiopulmonary resuscitation (CPR) until medical professionals arrive on the scene. In some places, emergency medical services may also provide instructions on how to use an automated external defibrillator (AED) if one is available nearby. It is crucial to act quickly and follow the guidance of medical professionals in such emergencies.
