Important Definitions

Ventricular Fibrillation (VF): The most common abnormal rhythm the heart goes into during sudden cardiac arrest. The heart’s electrical signals stop making sense, which causes fibrillation, or quivering, of the ventricles preventing them from contracting.

Defibrillation: A process of delivering an electrical shock that disrupts a heart’s electrical activity long enough to allow the heart to spontaneously develop an effective rhythm on its own.

Automated External Defibrillator (AED): A machine which delivers an electric shock which disrupts the abnormal electrical activity long enough to allow the heart to develop an effective rhythm on its own.

Learning Objectives

Understand the importance of defibrillation for a person with a cardiac emergency.

Know the right placement of the AED electrodes on a person.

Read the proper steps in application of the AED.

Familiarize yourself with AED precautions.

Differentiate the AED process between adult, child and infant.

Trials

for

Patients with Cardiac Arrest

Korean Red Cross

As mentioned earlier, most people in sudden cardiac arrest need an electric shock called defibrillation. Each minute the defibrillation is delayed, the chances of survival are reduced by about 10 percent. Therefore, the sooner the shock is administered, the greater the chances are that the person will survive. By learning how to use an AED, you can make a difference before EMS personnel arrive.

Using an AED - Adult

on the AED.

Wipe

the person’s bare chest dry. Apply the pads to the person’s bare chest. Place one pad on the upper right chest and the other pad on the lower left side.

Using an AED - Adult

Plug the connector into the AED, if necessary.

Using an AED - Adult

Let

the AED analyze the heart rhythm (or push the button marked “analyze,” if indicated and prompted by the AED).

 Advise all responders and bystanders to “Stand clear.”

 Do not touch the person.

Using an AED - Adult

Deliver a shock by pushing the button if indicated and prompted by the AED. Ensure that no one, including you, is touching the person and that there are no hazards present (such as puddles of water).

 If the AED tells you “No shock advised,” you may have to continue CPR.

Using an AED - Adult

Continue to administer CPR.

 In some cases, defibrillation is not required and the AED will not prompt you to deliver a shock. If no shock is indicated, leave the AED attached to the person and continue CPR for 5 cycles (or about 2 minutes). Continue care as needed.

Using an AED - Adult

Sudden cardiac arrest can happen to anyone, at any time and not just to adults. While the incidence is relatively low compared with adults, cardiac arrest resulting from VF does happen to young children and infants and is no less dramatic.

AEDs equipped with pediatric AED pads are capable of delivering lower levels of energy to a child between 1 and 8 years of age or less than 25 kilograms. Use the same general steps and precautions that you would when using an AED on an adult. The only difference is if the pads risk touching each other, place one on the child’s chest and the other on the child’s back.
