How to use an Automated External Defibrillator (AED)

An Automated External Defibrillator (AED) is a lifesaving device that can restore a normal heart rhythm in victims of sudden cardiac arrest. This step-by-step guide will walk you through how to use an AED correctly.

Step 1: Assess the Situation

Before using an AED, it is crucial to assess the situation. Make sure the victim is unconscious and not breathing or breathing abnormally. If this is the case, begin CPR (cardiopulmonary resuscitation) and have someone fetch the AED immediately.

Step 2: Turn on the AED

Once you have the AED, turn it on. Most devices have a large, clearly marked "on/off" button. Once turned on, the AED will guide you through voice or visual instructions.

Step 3: Expose the Victim's Chest

It is important that the victim's chest is exposed to allow good contact between the skin and the AED electrodes. Remove any clothing that might get in the way. If the victim is wet, dry the chest before applying the pads.

Step 4: Apply the Pads

AED electrodes, also called pads, should be applied to the victim's bare chest. An electrode should be placed on the upper right side of the chest, below the collarbone. The other should be placed on the left side of the chest, below and to the left of the chest.

Step 5: Analyze Heart Rhythm

Once the pads are in place, the AED will automatically analyze the victim's heart rhythm. It is vital that no one touches the victim during this time.

Step 6: Manage Shock

If the AED determines that a shock is needed, it will instruct you to do so. Make sure no one is touching the victim, then press the "shock" button. If the AED is fully automatic, it can deliver the shock on its own.

Step 7: Continue CPR

After the shock, continue CPR until emergency services arrive or the victim begins to move or breathe normally.

Final Considerations

It is important to remember that the use of an AED should always be combined with CPR. Also, even if a shock is administered and the victim appears to recover, it is essential that emergency services are called. The victim should always be evaluated by medical professionals after a cardiac arrest event.

In summary, an AED is an essential first aid tool that can save lives. Knowing how to use one can make all the difference in an emergency situation.
