AED Defibrillators: Types of AEDs And Their Uses

On 28 Dec., 2020

Automatic External Defibrillator (AED) is a battery-operated portable electronic medical device that automatically recognizes the life-threatening electrical abnormalities of ventricular fibrillation and ventricular tachycardia. The electrical impulses from the heart are transformed into currents that pass through the body tissues. This technology is an indispensable tool for cardiologists during cardiac arrest or rhythm unknown diseases. It also provides relief to those who are affected with it.

AED Defibrillators: Types of AEDs And Their Uses

Types Of AED Defibrillators


The AED device contains devices that are required for the AED to detect and interpret an electrocardiogram and produce an electric shock, such as a battery and pad electrodes. Here are two main types of AED:


  • Public Access AEDs - Airports, community centers, colleges, state offices, hospitals, and other public locations can be found. They are intended for lay people who have undergone minimum training to use them.

  • Professional AED - First responders, such as emergency medical technicians (EMTs) and paramedics, who undergo more AED training, are used.


AED Defibrillator Provides 


The aed defibrillator provides 


  • More relief during sudden cardiac arrest. 

  • It has a faster recovery time 

  • Allows for a more flexible management of the patient's medical condition.


How To Use AED Defibrillator


There are things to remember when you are using AED Defibrillator 


  • Electrodes are placed on the patient's chest or neck. 

  • When a patient is placed on the aed defibrillator pads, these devices provide an electric shock to the person's defibrillated tissue. 

  • The electric shock disrupts the electrical rhythm of the heart. 

  • Then patients would feel a slight discomfort and tingling sensations in the area where the shock is being delivered. This is usually temporary.


When Should You Use AED?


The ones who are most commonly advised to use AEDs in emergency situations are the following; 


  • Patients with severe aortic stenosis 

  • old age patient 


There are also some patients that need a lesser chance to be given a defibrillation treatment. 


  • Patients with pulseless ventricular fibrillation 

  • Patients with ventricular tachycardia 


Who should not use an AED?


There are some instances that patient shock-treatment is not applicable because of some circumstances their hearts are not in a normal rhythm when they are exposed to a shock. They may recover from ventricular fibrillation or cardioembolism eventually, but it takes a few months. For this reason, people who have cardioembolism should not use the red electrode pads.


When Should You Use Red Electrode Pads


Patients should use the red electrode pads only when a sudden, unforeseen situation has already made it impossible for them to undergo standard CPR or cardiac arrest techniques. In such cases, it is vital to give emergency first aid or cardiopulmonary resuscitation before administering an AED. 


What Happen During Defibrillating Process


During the defibrillating process, a series of electrodes are attached to the patient's chest or to his or her neck. If the aed shock is administered too suddenly, there is a high risk of excessive shocks or injury.


How AED Differs?

  • The most common and efficient units are those that use a battery-operated compressor. 

  • However, more advanced defibrillators are available that work on the same principle as a belt-driven pump. 

  • Some manufacturers provide child pads with the AED units, while others recommend that they be used without the help of child pads.


When Should AED Be Use Or Not


Aside from the differences in the size and operation method, there are other factors that should be taken into account when determining whether a particular AED model should be used or not. 

it is important to determine the patient's current or anticipated current or future heart rate.

This will allow the aed to be adjusted according to the patient's heart rate so that it will not cause discomfort.  Moreover, a rhythm analyzer is necessary so that a patient will be able to determine the right time to administer the AED or to use the voice prompts.  Most models come with a rhythm analyzer that can be used at home, but there are also some models that require a medical professional's assistance in using it.


Lifespan AED Defibrillators


The lifespan AED defibrillators are lightweight portable aed defibrillator units that are usually used by paramedics and emergency medical technicians.The lifespan AED pads are typically used on patients that suffer from life-threatening emergencies. 




If you are planning to buy an automated external defibrillators unit, be sure to choose one that is safe for the users and the environment. You can choose from a wide variety of AED units that include the handheld, wall-mounted and the lifespan AED pads.
