  • Section 1

4 questions that narrow your AED choice in under a minute.

Quick Answer

Four variables drive 90% of AED fit decisions: indoor or outdoor placement, untrained or CPR-trained responders, whether children under 8 will be present, and unit count. Each question rules out roughly half of the FDA-cleared lineup.

1. Indoor or outdoor placement?

Indoor only: any IP-rated model works. Outdoor or humid environments (pool deck, sports field, marina): require IP56 minimum — the HeartSine 450P is the only mainstream consumer AED at this rating.

2. Untrained or CPR-trained responder?

Untrained office staff win with Philips voice-prompt simplicity. CPR-trained teams (gym, healthcare, first responders) benefit measurably from ZOLL’s real-time compression depth coaching. See CPR + AED training resources.

3. Children under 8 ever present?

Pediatric capability is required for children under 8 or under 55 lbs per American Red Cross guidance. Single-key models (Philips FRx) beat pad-swap models for non-medical staff under rescue stress.

4. Single unit or multi-location fleet?

1-4 units: manual tracking + any model works. 5+ units across separate locations: cellular fleet management pays back — LIFEPAK CR2 with LIFENET or ZOLL AED 3 with PlusTrac. Fleet management via AEDTS.

  • Section 2

What is an AED and how is it regulated?

Quick Answer

An automated external defibrillator (AED) is a portable medical device that analyzes a patient’s heart rhythm and delivers an electrical shock if defibrillation is indicated. The FDA classifies AEDs as Class III medical devices under the 510(k) clearance pathway. As of 2022, no prescription is required to purchase a consumer-class AED in the United States.

AEDs are designed for use by lay rescuers — the device handles rhythm analysis automatically, so the operator doesn’t need to interpret an ECG. Every FDA-cleared model walks the rescuer through every step with voice prompts. The device decides whether to shock; the rescuer applies pads and follows audio cues.

What an AED does not do: it does not treat heart attacks (myocardial infarctions), it does not restart a stopped heart, and it does not replace CPR. The rescue sequence is AED + CPR + EMS together — no single component substitutes for the others.

  • Section 3

How an AED works — 6 steps 90 seconds to first shock.

Quick Answer

An AED executes 6 steps in roughly 90 seconds from power-on to first shock: power on, pad placement, rhythm analysis, shock decision, shock delivery, CPR cycle. The device handles rhythm interpretation; the rescuer handles pad placement, clearing the patient before shock, and CPR between cycles.

1

Power on

Open the AED. Most devices power on when the lid opens. Voice prompts begin in plain English. Philips OnSite uses pull-handle activation.

2

Apply pads

Expose the patient's bare chest. Apply electrode pads per the pictogram. Upper right chest and lower left side for adults. Pediatric pads or pediatric mode for children under 8.

3

Stay clear

Device announces "Analyzing heart rhythm. Do not touch patient." Wait 5-10 seconds while the device interprets the rhythm.

4

Shock decision

Two outcomes. "Shock advised" = ventricular fibrillation or pulseless VT, device proceeds to deliver. "No shock advised" = continue CPR; device re-analyzes every 2 minutes.

5

Deliver shock

Semi-automatic prompts the rescuer to press the shock button. Fully-automatic delivers after countdown. Shock energy: ~150-200 joules adult, ~50 joules pediatric.

6

CPR cycle

Device announces “Begin CPR.” Compress at 100-120 BPM, depth 2.0-2.4 inches per AHA 2020 Resuscitation Guidelines. Continue until EMS arrives.
  • Section 4

The 7 features that actually affect outcomes.

Quick Answer

Seven device features measurably affect rescue outcomes and ownership cost: CPR feedback, pediatric mode, IP rating, pad and battery shelf life, ease of use under stress, automatic self-test, and device weight. Most other “features” are marketing.
FeatureWhat It MeansWho Needs It
CPR feedbackAccelerometer measures compression depth + rate in real time, coaches the rescuer via voice + visualGyms, healthcare, CPR-trained teams — ZOLL AED Plus
Pediatric modeReduces shock energy for patients under 8 / under 55 lbs (single-key, built-in button, or pad swap)K-12 schools, daycares, family fitness, pediatric clinics
IP ratingDust + water resistance per IEC 60529. IP55 = jet water; IP56 = powerful jet water; IPX4 = splash onlyOutdoor sports, pool deck, marine
Pad + battery life2-5 years before mandatory replacement. Longer cycle = lower 5-year consumables costBudget-conscious + low-touch ops
Ease of useHow fast an untrained person deploys correctly under stress (voice prompts, pull-handle, audible cues)High-turnover, inconsistent-training environments
Self-testDaily / weekly / monthly automatic checks on battery, pads, readiness. Reduces inspection burdenUnmonitored locations, no dedicated AED program staff
Weight2.4 lbs (HeartSine 350P) to 7+ lbs (LIFEPAK CR2). Affects mounting + travel useOutdoor deployment, travel AEDs, sports teams
  • Section 5

2026 AED pricing —9 FDA-cleared models.

Quick Answer

FDA-cleared AED prices in 2026 range from $995 (HeartSine 350P) to $2,450 (LIFEPAK CR2). Mid-range consumer AEDs run $1,529-$2,240. All prices below reflect 2026 authorized US distributor reference points and exclude consumables, cabinet, training, and registration.

  • Section 6

5-year total cost — sticker is 50-65% of the real number.

Quick Answer

A $1,944 AED is not a $1,944 program. Over 5 years, pads, batteries, cabinet, training, and inspection add 40-80% on top of sticker. The real budget for most facilities runs $1,800-$4,500 per AED over 5 years. Run the AED Cost Calculator for your exact device.
Cost ItemFrequencyTypical RangeNotes
AED deviceOne-time$995-$2,450Device only, before accessories
Electrode padsEvery 2-5 yr$25-$150 per setReplace after any rescue use
BatteryEvery 2-5 yr$90-$350HeartSine Pad-Pak combines both, 4-yr cycle
AED cabinetOne-time$50-$500Basic wall-mount to alarmed cabinet
Annual inspectionAnnual$0-$150/yrDIY = $0. Service contract = $75-$150/yr per AED

Medical directionAnnual$0-$500/yrRequired in NY and select states
EMS registrationOne-time or annual$0-$50Required in 27 states
5-year program total$1,800-$4,500Per AED, all-in
A $1,944 Philips FRx needing $480 in pads + $660 in battery over 5 years runs ~$2,400+ before cabinet and inspection. A $995 HeartSine 350P with one 4-year Pad-Pak replacement ($120) often costs less over 5 years than 2-year-cycle alternatives.
  • Section 7

How many AEDs does your facility need?

Quick Answer

The AHA 3-minute drop-to-shock standard requires any point in your facility to be within 3-minute round-trip retrieval of an AED. Typical office: 22,000 sq ft per AED. Typical gym: 10,000 sq ft per AED (1.5× risk per NEJM 2000). Typical school: 20,000 sq ft per AED. Add one per additional floor and per detached building.
Building TypeSq Ft / AEDRisk Multiplier
Open warehouse / factory floor~30,0001.0×
Restaurant / retail~25,0001.0×
Office / corporate~22,0001.0×
Hotel / hospitality~18,0001.0×
School / daycare~20,0001.15× (K-12 athletic)
Healthcare / clinic~15,0001.0×
Gym / fitness facility~10,0001.5× (NEJM 17× SCA risk during exertion)
Survival from SCA drops 7-10 percentage points per minute without defibrillation. Stair and elevator transit consumes 60-90 seconds, so one AED cannot cover multiple floors within the 3-minute window. Plan at least one AED per occupied floor. Run the Quantity Calculator for your exact count.
  • Section 8

  • Section 10

Pediatric capability — non-negotiable for schools, daycares, family.

Quick Answer

Children under 8 or under 55 lbs require lower-energy defibrillation per American Red Cross and AHA pediatric protocols. Three pediatric architectures exist: single-key insert, built-in child mode button, and separate pediatric pads. Single-key models (Philips FRx) are operationally simplest under rescue stress.
Pediatric ArchitectureHow It WorksBest For
Single Infant/Child KeyInsert key — device reconfigures for pediatric energy. No pad swap.Philips FRx — K-12, daycares, family facilities
Built-in child mode buttonPress button — device delivers pediatric energy. No pad swap.LIFEPAK CR2 · Cardiac Science G5
Universal pediatric pads (Uni-padz)Single pad set works for adult or pediatric — flip switch on deviceZOLL AED 3
Separate pediatric pads (swap)Remove adult pads, apply pediatric pads. Highest cognitive load under stress.Philips OnSite, HeartSine 350P, Defibtech
  • Section 11

Outdoor durability — which IP rating do you actually need?

Quick Answer

IP ratings have two digits per IEC 60529. First = dust protection (0-6). Second = water (0-9). IP55 handles jet water from any direction (Philips FRx, ZOLL AED Plus, LIFEPAK CR2). IP56 handles powerful jet water — highest mainstream rating (HeartSine 350P/450P). IPX4 handles splash only (Defibtech). For sustained outdoor weather, require IP55+ with a heated outdoor cabinet.
For a 60,000 sq ft K-12 school with detached athletic fields, indoor units can be IP21 or IP55, but the athletic field cabinet requires IP55+ device with an outdoor heated cabinet ($350-$500). For a marina, pool deck, or industrial outdoor: IP56 only — HeartSine 450P is the only mainstream consumer AED at this rating.
  • Section 12

Where to buy — do you authorized US distributors only.

Quick Answer

Gray-market AEDs save ~10% upfront and create three downstream risks: void warranty, miss FDA recall notifications, and complicate Good Samaritan owner protection in 14+ states where owner maintenance is a protection condition. Always purchase through authorized US distributors and verify the model is currently listed in the FDA 510(k) database.

Authorized US distributors maintain manufacturer warranty pass-through, receive direct FDA recall notifications routed to registered owners, and supply consumables through the manufacturer-sanctioned channel. Verify the model on the FDA 510(k) database before purchase.
