Which of the Following Statements Regarding the AED and Defibrillation Is Correct?

Automated External Defibrillators (AEDs) are portable devices used to deliver an electric shock to the heart in cases of sudden cardiac arrest (SCA). They have become a vital tool in saving lives, as early defibrillation is crucial for successful resuscitation. However, there are several misconceptions and questions surrounding AEDs and defibrillation. In this article, we will explore the correct statements regarding AEDs and address frequently asked questions.

Correct Statements Regarding AED and Defibrillation:

1. AEDs are designed for use by non-medical personnel: AEDs are specifically developed to be user-friendly and can be operated by individuals with minimal or no medical training. The device provides clear and concise instructions on how to use it effectively. The goal is to make AEDs accessible to the general public, enabling prompt response and potentially saving lives before professional medical help arrives.

2. AEDs analyze the heart rhythm: When an AED is applied to a person experiencing SCA, it will analyze the heart rhythm to determine if a shock is required. The device can distinguish between shockable rhythms, such as ventricular fibrillation (VF) or ventricular tachycardia (VT), and non-shockable rhythms like asystole or pulseless electrical activity (PEA). This analysis ensures that a shock is only delivered when necessary, increasing the chances of successful defibrillation.

3. Defibrillation is the delivery of an electric shock: Defibrillation is the process of delivering an electric shock to the heart to reset its rhythm. This shock interrupts the chaotic electrical activity in the heart during SCA and allows the heart to resume its normal rhythm. AEDs are equipped with electrodes or pads that are placed on the chest of the individual in distress. The device delivers a controlled electric shock through these electrodes, aiming to restore the heart’s natural rhythm.

4. CPR should be performed before and after defibrillation: Cardiopulmonary resuscitation (CPR) is a vital component of the chain of survival during SCA. Before using an AED, it is crucial to initiate CPR by providing chest compressions and rescue breaths. CPR helps maintain blood flow to vital organs until defibrillation can be administered. After defibrillation, CPR should be continued until professional medical assistance arrives.

5. AEDs are safe to use: AEDs are equipped with built-in safety features and algorithms that ensure they deliver shocks only when necessary. The devices are designed to minimize the risk of harming the individual or the operator. The AEDs also provide voice prompts and visual cues to guide the user throughout the process. It is important to note that AEDs should only be used on individuals who are unresponsive and not breathing normally.


Q1. Can using an AED harm the person in distress?
A1. AEDs are designed to deliver shocks safely and effectively. The devices analyze the heart rhythm and only deliver a shock if it is required. The electric shock is controlled and aimed at restoring the heart’s normal rhythm. However, it is important to follow the device’s instructions and use it only on individuals who are unresponsive and not breathing normally.

Q2. Are there any age restrictions for using an AED?
A2. AEDs can be used on individuals of all ages, including children and infants. However, some AED models may have pediatric pads or settings specifically designed for younger individuals. These pads or settings adjust the energy level of the shock to suit the needs of pediatric patients.

Q3. Can AEDs be used on individuals with implanted devices, such as pacemakers or defibrillators?
A3. AEDs can be used on individuals with implanted devices. The shock delivered by the AED may affect the implanted device, but the potential benefits of defibrillation outweigh the risks. The AED pads should be placed at least one inch away from the implanted device if possible.

Q4. Are AEDs only found in public places?
A4. AEDs are commonly found in public places such as airports, shopping malls, sports facilities, and schools. However, they can also be found in private residences, workplaces, and vehicles. Having an AED readily available in various settings increases the chances of timely defibrillation and improves survival rates.

In conclusion, AEDs play a crucial role in saving lives during sudden cardiac arrest. Their user-friendly design allows non-medical personnel to effectively use them in emergencies. AEDs analyze heart rhythms and deliver controlled electric shocks to restore normal cardiac activity. It is essential to initiate CPR before and after defibrillation and follow the device’s instructions carefully. AEDs are safe to use, provided they are used on appropriate candidates and in accordance with guidelines.
