How to Use an AED Machine: A Simple and Complete Guide
Knowing how to use an Automated External Defibrillator (AED) can save lives in cases of sudden cardiac arrest. You don’t need to be a medical professional to use an AED—these machines are designed for anyone to operate easily and effectively. In this guide, you’ll learn what an AED is, when and how to use one, and best practices to ensure you’re prepared in an emergency.
What Is an AED and Why Is It Important?
An AED is a portable device that checks a person’s heart rhythm and can send an electric shock to the heart. This shock may help the heart re-establish an effective rhythm. AEDs are found in many public spaces like schools, airports, offices, and shopping centers, because sudden cardiac arrest can happen to anyone, anywhere, at any time.
Key Points:
– AEDs are easy to use, with clear instructions and voice prompts.
– Using an AED quickly increases the chances of survival for cardiac arrest victims.
– AEDs are safe: they only deliver a shock if it’s needed.
When Should You Use an AED?
Use an AED when someone:
– Suddenly collapses and is unresponsive.
– Is not breathing normally or isn’t breathing at all.
– Has no pulse (if you have training to check this).
If you see these signs, act fast. Every minute counts—survival drops by 10% for every minute without defibrillation.
Step-by-Step: How to Use an AED
When you’re faced with an emergency, keep calm and follow these steps:
1. Check the Scene and the Person
Before anything else:
– Make sure the area is safe for you and the victim.
– Tap the person and shout, “Are you okay?”
– Check for breathing. If the person isn’t breathing or is only gasping, they need immediate help.
2. Call Emergency Services (or Direct Someone Else To)
- Dial your local emergency number right away.
- If you’re with others, ask someone specifically to call for help and get an AED immediately.
3. Start CPR While Waiting for the AED
- Begin chest compressions: place your hands over the center of the chest and push hard and fast (about 100-120 compressions per minute).
- If you are trained, give rescue breaths after every 30 compressions. If not, focus on chest compressions.
4. Turn On the AED
- As soon as the AED arrives, turn it on by pressing the power button or opening the lid. Most AEDs will give you voice prompts.
5. Expose the Person’s Chest and Apply the Pads
- Remove any clothing covering the chest. If necessary, dry the chest and shave off excessive hair where the pads will go.
- Peel the backing off the sticky AED pads.
- Place one pad on the upper right chest, just below the collarbone.
- Place the other pad on the lower left side of the chest, a few inches below the armpit.
6. Let the AED Analyze the Heart Rhythm
- Check that no one is touching the person.
- Press the “analyze” button if the device has one (some AEDs analyze automatically). Listen to the AED’s instructions.
7. Deliver a Shock (If Advised)
- If the AED determines a shock is needed, it will tell you.
- Make sure everyone stands clear.
- Press the shock button when prompted. The AED will deliver an electric shock to the person’s heart.
8. Resume CPR
- After the shock is delivered (or if no shock is advised), start CPR right away.
- Continue CPR for about two minutes, or until the AED tells you to stop so it can re-analyze the heart rhythm.
- Alternate between CPR and following the AED’s prompts until emergency help arrives or the person shows signs of life.
Practical Tips and Best Practices
Being prepared can make all the difference in a crisis. Here are some practical tips to keep in mind:
Get Familiar with AED Devices
- Take a first aid or CPR/AED course to gain confidence.
- Look for AEDs in places you visit often, such as your workplace or gym—know where they are located.
Clear Communication
- Assign tasks if others are present: someone calls emergency services, another gets the AED, another starts CPR.
- Remain calm and speak clearly.
Safety First
- Do not use an AED in water or if the victim is lying in a puddle. Move them to a dry area when possible.
- Remove any medication patches on the chest where the pads will go.
- If the victim has a pacemaker (a small lump under the skin), don’t place the pad directly over it.
Child and Infant Use
- Use pediatric pads for children under 8 years or under 55 pounds, if available.
- If child pads aren’t available, use adult pads—never delay defibrillation.
After Use
- Leave the AED attached to the person until EMS arrives. Emergency personnel need to see the data and continue treatment.
Benefits of Prompt AED Use
Using an AED quickly can mean the difference between life and death.
- Dramatically improves survival rates: Early defibrillation combined with CPR can improve survival by up to 70%.
- Reduces brain damage: Every minute without a heartbeat increases the risk of permanent brain injury.
- Empowers bystanders: AEDs are designed to guide even untrained people to save lives confidently.
Common Challenges and How to Overcome Them
Fear and Hesitation
Many people worry about hurting the victim or using the AED incorrectly. Remember, AEDs are made to be safe—you can’t accidentally harm someone who doesn’t need a shock. Always act rather than wait.
Unfamiliarity with the Device
Practice with training AEDs during safety drills or in CPR/AED courses to build muscle memory.
Access to AEDs
Not all locations have obvious AEDs. Advocate for AED placement in your community and workplaces. Encourage everyone to notice where AEDs are located.
Summary
Using an AED during sudden cardiac arrest is one of the most effective ways to save a life. The process is simple:
- Recognize the emergency.
- Call for help and fetch the AED.
- Follow the device’s prompts.
- Begin and continue CPR as needed.
AEDs are designed to be used by anyone, and your actions can make the critical difference. Don’t hesitate—act fast, follow the steps, and know you’re making an impact.
Frequently Asked Questions (FAQs)
1. What if I use an AED on someone who doesn’t need it?
AEDs are safe. They only deliver a shock if the person’s heart rhythm indicates it is needed. If the person does not need a shock, the device will never deliver one, so there is no risk of harming them by trying.
2. Can I use an AED on a child?
Yes. Use child pads and settings if the child is under 8 years old or under 55 pounds. If only adult pads are available, use those—do not delay defibrillation.
3. Can I use an AED in the rain or on a wet surface?
No. Move the victim to a dry area before using the AED. Remove any wet clothing and dry the chest thoroughly where the pads will be placed before proceeding.
4. What if someone has a lot of chest hair or is wearing a necklace?
If chest hair prevents pads from sticking, quickly shave the area using a razor from the AED kit. Avoid placing pads over jewelry, but do not waste time trying to remove jewelry; simply place the pads a little away from the metal.
5. Should I remove medication patches before applying AED pads?
Yes. Remove any medication patch where you need to place a pad, then wipe the area clean. This prevents burns and ensures the shock is delivered most effectively.
If you ever find yourself in an emergency, remember: the quickest response saves lives. Don’t be afraid to step up and use an AED—these user-friendly, life-saving devices are there for you to help when seconds matter most.
