How to Use an AED?

1. What is an AED?

An AED (Automated External Defibrillator) is a portable medical device designed to detect and treat dangerous heart rhythm disorders (arrhythmias) by delivering an electric pulse to the heart. In cases of sudden cardiac arrest, the AED plays a pivotal role in restoring a normal heart rhythm, significantly increasing patient survival rates if used within the first 3–5 minutes.

A unique feature of the AED is that anyone can use it without specialized medical training. The device is programmed with clear, step-by-step voice prompts, enabling laypeople to perform timely first aid in emergencies and potentially save lives before an ambulance arrives.

2. When Should an AED Be Used?

Recognizing the right moment to use an AED can save a victim during critical life-or-death moments. Rescuers should use the defibrillator in situations where the victim is experiencing cardiac arrest, is completely unconscious, unresponsive to shaking or calling, and is not breathing or breathing abnormally (gasping), with no detectable pulse.

However, there are cases where an AED must NOT be used. Absolutely do not use an AED if the victim is conscious, breathing normally, or has a distinct pulse. Do not use it on wet surfaces or if the victim is lying in a pool of water, as electricity can conduct through water and cause danger.

Before administering a shock, ensure important safety protocols are met. Check the surroundings to ensure no one is touching the victim. Wipe the victim's chest dry if wet, remove metal objects like necklaces, and cut away clothing to ensure the electrode pads make direct contact with the skin. These preparatory steps ensure the effectiveness of the shock and the safety of both the rescuer and the victim.

• Step 1: Begin by quickly assessing the surroundings to ensure safety. Check the victim's condition by tapping their shoulders and shouting loudly. If there is no response, immediately call the emergency number (115) or ask bystanders to call for help and locate the nearest AED.
• Step 2: Once the AED is available, open the case and power it on immediately. The machine will automatically emit clear, easy-to-understand voice prompts. Listen carefully and follow every instruction the machine provides.
• Step 3: Attach the two electrode pads to the victim's bare chest. Place one pad on the upper right side of the chest (below the collarbone) and the other on the lower left side (below the armpit). Ensure the pads adhere firmly to the skin without wrinkles or gaps.
• Step 4: After the pads are attached, the machine will automatically analyze the victim's heart rhythm. During this phase, absolutely do not touch the victim and ensure everyone stands clear to allow for accurate analysis.
• Step 5: If the machine determines a shock is necessary, it will issue a warning signal. Ensure no one is touching the victim, then press the shock button as instructed. Some modern AEDs will deliver the shock automatically without needing a button press.
• Step 6: Immediately after the shock, continue performing CPR at a ratio of 30 chest compressions to 2 rescue breaths until medical personnel arrive or the victim shows signs of regaining consciousness. The AED will continue to monitor and guide you throughout the rescue process.

4. Benefits of Proper AED Training

AED training helps learners master not only technical operations but also understand the operating principles and how to handle various situations. Through practice on simulation models, trainees become familiar with the device, minimizing anxiety and panic during actual incidents.

Well-trained individuals can react faster, perform steps more accurately, and coordinate CPR more effectively. This directly increases a cardiac arrest victim's survival rate from 10% to 70% if proper first aid is administered within the first 3–5 minutes.

Furthermore, an AED training certificate is a valuable asset in the workplace, demonstrating community responsibility and emergency response skills.
