What is the use of an AED?

• A. To provide medication directly to the patient
• B. To analyze the heart rhythm and deliver an electric shock if necessary
• C. To maintain body temperature
• D. To assist in CPR procedures

Answer: (B)

An Automated External Defibrillator (AED) is specifically designed to analyze a person's heart rhythm and determine whether an electric shock is needed. When a patient experiences a cardiac arrest due to certain arrhythmias, such as ventricular fibrillation or pulseless ventricular tachycardia, the AED can deliver a controlled electric shock to the heart. This shock can help restore a normal rhythm by resetting the heart's electrical activity.

The AED performs critical functions by checking the heart’s electrical activity and instructing the user on whether a shock should be administered. This capability makes it an essential tool in emergency situations, as timely defibrillation can significantly increase the chances of survival for individuals experiencing sudden cardiac events. The device is designed for use by laypersons and medical professionals alike, often providing voice prompts and visual indicators to guide the user through the process.

Other options do not accurately describe the AED’s function. Medication administration is not within the capabilities of an AED. Maintaining body temperature or specifically assisting in CPR without defibrillation are not primary functions of the device either. The focus of an AED is on rhythm analysis and providing defibrillation when indicated.
