Using an Automatic External Defibrillator (AED) Korean Red Cross Important Definitions  Ventricular Fibrillation (VF): The most common abnormal rhythm the heart goes into du ring sudden cardiac arrest. The heart’s electrical signals stop making sense, which cau ses fibrillation, or quivering, of the ventricles preventing them from contracting.  Defibrillation: A process of delivering an electrical shock that disrupts a heart’s electric al 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 wh ich disrupts the abnormal electrical activity long enough to allow the heart to develop a n 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.

The Importance of Defibrillator 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.

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. Korean Red Cross 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.

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.

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.

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.

Korean Red Cross AED Precautions Do not touch the person while the AED is analyzing. Touching or moving the person may affec t the analysis. Do not touch the person while the device is defibrillating. You or other could be shocked. Prior to shocking a person with an AED, make sure that no one is touching or is in contact wit h the person or the resuscitation equipment. Do not use alcohol to wipe the person’s chest dry. Alcohol is flammable. Do not defibrillate someone when around flammable materials such as gasoline or free-flowin g oxygen. Do not use an AED in a moving vehicle. Movement may affect the analysis. Do not use an AED on a person who is in contact with water. Move people away from puddles of water or swimming pools, or out of the rain before defibrillating. Do not use an AED and/or electrode pads designed for adults on a child under 8 or less than 2 5 kilograms unless pediatric pads specific to the device are not available. Do not use a cellular phone or radio within 6 feet of the AED. This may interrupt analysis.
