Verified step by step guidance1
Step 1: Understand what an AED (Automated External Defibrillator) is — it is a medical device used in emergencies involving cardiac arrest.
Step 2: Recognize that the heart can sometimes develop an irregular rhythm, such as ventricular fibrillation, which prevents it from pumping blood effectively.
Step 3: Know that the primary function of an AED is to analyze the heart's rhythm and deliver an electric shock if necessary to correct this irregular rhythm.
Step 4: This electric shock helps to 'reset' the heart's electrical system, allowing it to restore a normal, regular heartbeat.
Step 5: Differentiate this function from other options like increasing heart rate, assisting with breathing, or performing chest compressions, which are not the primary roles of an AED.
