Final answer:
In a situation where a victim becomes unresponsive, CPR should be initiated. If alone, provide about two minutes of CPR before activating emergency response and retrieving an AED. AEDs provide essential assistance in correcting abnormal heart rhythms.
Step-by-step explanation:
CPR and AED in Emergency Situations
In the event of a cardiac emergency where the victim becomes unresponsive, CPR (cardiopulmonary resuscitation) is recommended. If you are not alone, you should begin CPR and then send someone to activate the emergency response system and retrieve an AED (Automated External Defibrillator). If you are alone, the recommended practice is to provide around two minutes of CPR before leaving to activate the emergency response system and retrieve an AED yourself. AEDs are portable devices designed to diagnose the patient's heart rhythm and then apply a shock with appropriate energy and waveform to correct abnormal heart rhythm and potentially save a life.
