AED Training: How to Use an Automated External Defibrillator
An AED (automated external defibrillator) analyzes heart rhythm and delivers a shock if needed. AED training walks you through powering on, pad placement, voice prompts, and how to clear the patient before a shock.
Quick facts
- AEDs are designed for untrained bystanders to use
- Defibrillation within 3–5 minutes can yield survival rates above 50%
- Pads attach upper-right chest and lower-left side
- Don't touch the patient while the AED analyzes or shocks
The four steps
1) Power on. 2) Attach pads to bare, dry skin. 3) Stand clear while it analyzes. 4) Press shock when prompted, then immediately resume compressions.
Special situations
Wet skin — dry it. Hairy chest — shave or press pads firmly. Medication patch — remove and wipe. Pacemaker — place pads at least one inch away from the device.
Where to find AEDs
Airports, schools, gyms, malls, government buildings, and many offices. The PulsePoint AED app maps registered devices in your community.
Frequently asked questions
- Can I shock someone who doesn't need it?
- No — an AED only delivers a shock if it detects a shockable rhythm.
- Do AEDs work on children?
- Yes — use pediatric pads for children under 8 if available.
- Do I need training to use an AED?
- Legally no, but training significantly improves speed and confidence under stress.

What Is CPR? A Plain-English Guide to Cardiopulmonary Resuscitation
CPR (cardiopulmonary resuscitation) combines chest compressions and rescue breaths to keep blood and oxygen moving during sudden cardiac arrest.
Hands-Only CPR
Hands-only CPR has two steps: call 911 and push hard and fast in the center of the chest at 100–120 BPM until help arrives. No breaths required.
Choking Response
For a conscious choking adult or child, use 5 back blows and 5 abdominal thrusts. If the person becomes unresponsive, start CPR immediately.
How to Perform CPR
Check the scene, check the person, call 911, open the airway, give compressions and breaths, attach an AED, and continue until help arrives.
