An Automated External Defibrillator (AED) is a life-saving device designed to treat sudden cardiac arrest (SCA). It delivers an electric shock to help the heart restore a normal rhythm. AEDs are made for use by bystanders, first responders, and medical professionals, and they are simple, safe, and effective—even with no medical training.
🧠 Why AEDs Matter in Cardiac Arrest
Sudden cardiac arrest can cause the heart to stop beating effectively. When this happens:
- CPR keeps oxygen flowing to the brain and vital organs.
- An AED is the only way to restart the heart if it’s in a shockable rhythm (like ventricular fibrillation).
👉 Using an AED within 3–5 minutes can increase survival rates by over 70%.
✅ When to Use an AED
Use an AED when a person is:
- Unconscious
- Not breathing normally (or only gasping)
- Unresponsive to shouting or shaking
🛠️ Step-by-Step: How to Use an AED
Step 1: Turn on the AED
- Press the power button or open the lid—this starts voice instructions.
- Some models power on automatically when opened.
Step 2: Expose the Chest & Attach Pads
- Remove clothing and wipe the chest dry.
- Peel the pads from their backing.
- Place pads firmly on bare skin:
- One pad on the upper right chest (below collarbone).
- One pad on the lower left side of the chest (below the armpit).
- For children (under 8 years), use pediatric pads if available.
Step 3: Let the AED Analyze the Heart Rhythm
- Ensure no one is touching the person.
- The AED will say: “Analyzing heart rhythm. Do not touch the patient.”
Step 4: Deliver a Shock if Advised
- If the AED says “Shock advised,” make sure everyone is clear.
- Press the shock button when prompted.
- Some AEDs shock automatically after warning.
Step 5: Resume CPR Immediately
- Begin CPR immediately after the shock (30 compressions to 2 breaths, or hands-only if untrained).
- Follow the AED prompts—it may tell you when to stop and re-analyze.
- Continue CPR and follow AED instructions until EMS arrives or the person shows signs of life.
⚠️ AED Safety Tips
- Do not use in water or if the chest is wet. Dry the skin first.
- Remove medication patches from the pad site before attaching AED pads.
- Do not place pads over pacemakers or metal jewelry.
- Avoid touching the person during analysis or shock.
🧩 What If an AED Is Not Nearby?
- Start CPR immediately and send someone to get an AED.
- Continue CPR until the AED arrives and follow the steps above.
📦 Where to Find AEDs
AEDs are commonly located in:
🏢 Airports, gyms, schools, malls, hotels, public buildings, stadiums, and office complexes.
Look for signs with a lightning bolt symbol or labels like:
👉 “AED” or “Defibrillator Inside”
🔁 Quick Summary: Chain of Survival
- Recognize cardiac arrest.
- Call 911.
- Start CPR.
- Use an AED ASAP.
- Continue care until EMS arrives.
✅ Conclusion: Be AED-Ready
Using an AED is easy, safe, and can save a life. Don’t be afraid—the AED walks you through the process with voice prompts. Every second counts during cardiac arrest, and your quick action can mean survival.
