Why AED Confidence Matters on the Job
Sudden cardiac arrest kills roughly 350,000 people outside of hospitals each year in the United States, and survival drops by about 10% for every minute that passes without defibrillation. If your role requires CPR/AED certification — whether you work in healthcare, education, fitness, childcare, construction, or corporate safety — you may be the person who reaches the device first. Knowing exactly what to do in the first 90 seconds is what separates hesitation from a save.
Step 1: Confirm the Need Before You Open the Case
An AED is only used on someone who is unresponsive and not breathing normally. Tap and shout to check responsiveness, scan the chest for 5 to 10 seconds, and call 911 or direct someone else to call while you retrieve the device. Agonal gasping is not normal breathing — treat it as cardiac arrest. Begin high-quality chest compressions immediately and continue until the AED is powered on and ready.
Step 2: Power On and Follow the Prompts
Open the lid or press the power button. Every AED delivers audible and often visual prompts that walk you through the sequence. Your job is to listen and comply without improvising. The device will tell you to attach pads, stand clear, and either deliver a shock or resume CPR. Modern units are designed so an untrained bystander can operate them — your training simply makes you faster and calmer.
Step 3: Place the Pads Correctly
Expose the bare chest. Wipe away sweat or water, shave excessive chest hair if a razor is included, and remove medication patches with a gloved hand. Place one pad on the upper right chest just below the collarbone and the other on the lower left side of the chest, a few inches below the armpit, so the heart sits between them. Pads should never overlap or touch. For children under 8 years old or under 55 pounds, use pediatric pads or the pediatric setting; if neither is available, adult pads are acceptable. Avoid placing pads directly over an implanted pacemaker — shift about one inch to the side.
Step 4: Clear the Patient for Analysis
When the AED says "analyzing," stop compressions and ensure nobody is touching the patient. Movement can cause an inaccurate rhythm reading. Announce loudly, "Clear!" and visually confirm that all hands are off, including your own.
Step 5: Shock Timing and Immediate CPR
If a shock is advised, press the shock button the instant the device is charged — every second of delay reduces effectiveness. If no shock is advised, do not assume the patient is fine. In both cases, resume chest compressions immediately after the shock or the prompt, starting with compressions rather than breaths. The AED will reanalyze roughly every two minutes. Continue cycles of CPR and analysis, leaving the pads attached, until EMS takes over or the patient shows clear signs of life.
