Quick answer
The pediatric pad trap
| Model | How it handles children | Pediatric part life | 10-year pediatric cost |
|---|---|---|---|
| ZOLL AED 3 | Built into the standard Uni-padz | 5 years, same as adult | $0 extra |
| Philips HeartStart FRx | Reusable Infant and Child Key | Hardware, not a consumable | One-time, about $139 |
| ZOLL AED Plus | Separate Pedi-padz II | 24 months | About $775 |
Scale that to a district and it stops being a product detail. A district running 12 AEDs on a model that needs separate pediatric pads is looking at roughly $9,300 in avoidable pediatric consumable spend over ten years, by the same calculation. That is a line item a business manager can act on, and it is why this page ranks the ZOLL AED 3 first even though it is not the cheapest device to buy.
There is a second cost that never appears on an invoice. Pediatric pads on a 24-month cycle sit inside a program built around five-year adult pads and multi-year batteries. They expire between checks. Expired pediatric pads in an elementary building is not a budget problem, it is a liability problem, and it is the most common quiet failure we see in school AED programs. Our AED pads and batteries guide covers the full replacement schedule by model.

Quick answer
This is the most useful thing a school buyer can learn in 2026 and none of the top-ranking guides mention it. The Cardiomyopathy, Health Education, Awareness, Research, and Training in Schools Act, H.R. 6829 in the 118th Congress, passed the Senate unanimously and was signed into law in December 2024. It directs HHS to support schools in obtaining AEDs and in training staff and students in CPR and AED use, and it incorporates provisions of the bipartisan Access to AEDs Act.
Two things to be precise about, because the distinction matters when you take this to a board. It creates a grant program, so funding is applied for rather than automatic. And it does not create a federal requirement to have AEDs in schools. If your district has been deferring an AED program on cost, the funding landscape changed and the deferral may no longer hold. Earlier federal grant frameworks also exist, including the Cardiac Arrest Survival Act and the Community Access to Emergency Devices Act.
Are AEDs required in schools?
Quick answer
We are giving you the sourced number rather than a confident-sounding one. The Sudden Cardiac Arrest Foundation, citing a 2022 review, reports that 20 states plus the District of Columbia require AEDs in schools. California separately mandates AEDs at schools offering athletic programs. Several guides publish higher or lower counts with no source attached, and we are not going to add another unverified figure to that pile. Because state legislatures move on this topic regularly, a 2022 count is a floor rather than a current total.
Check your own requirement, including inspection, registration and training obligations that often accompany the device mandate, in our K-12 AED requirements by state guide and the broader AED laws by state reference.
Is pediatric capability legally required?
Not federally, and this is where several school AED guides overstate the law. American Heart Association guidance prefers a pediatric-attenuated dose for children under 8 years or under about 55 pounds. It also states plainly that if pediatric pads are not available, adult pads can be used on a child or infant, because delaying treatment is worse than using the adult dose. So pediatric capability is essential in practice and strongly recommended, not a blanket legal requirement. Individual states may impose their own pediatric rules, so check your statute.
How many AEDs does a school need?
Quick answer
The AHA’s 2023 policy statement on cardiac emergency response planning for schools sets the standard as “enough AEDs such that the device can be retrieved and delivered to any location on the school campus within 3 minutes.” The same document reports that when CPR and defibrillation are performed within 3 minutes of sudden cardiac arrest rather than beyond it, survival increased to 74 percent. It also states AEDs should be accessible at any time of day or night, should never be locked in an office or stored away, and should carry clear signage.
Worked against real campuses, that standard usually produces more units than schools expect:
| Campus type | Typical minimum | The location people miss |
|---|---|---|
| Single-story elementary | 1 to 2 | The far wing at the end of a long corridor, and the playground |
| Multi-story middle school | 1 per floor | Stairwell time is the killer. A 3-minute round trip up and down two flights is not achievable from a single office unit |
| High school with athletics | 1 per building plus dedicated units | The stadium, which can sit several hundred yards from the nearest door, and the weight room |
| Any campus, after hours | Accessible unit outside locked areas | Evening games and community use, when the main office is locked and its AED is unreachable |
What actually matters when choosing a school AED
| Criterion | Why it matters in a school specifically |
|---|---|
| How pediatric is delivered | The one criterion that changes your ten-year budget and creates or removes an expiry date. Built into the pad beats a separate consumable |
| Usable by an untrained adult | The responder is usually a teacher or coach, not a clinician. Visual CPR feedback beats audio-only under stress |
| Durability | Gyms, fields and bus loops destroy equipment. IP55 or better |
| Maintenance burden | Fewer consumables and fewer expiry dates means fewer failures. One part beats two |
| Readiness visibility | Districts with many units need status at a glance rather than a walk-around |
| Total cost over 10 years | Purchase price is a fraction of program cost. Model it before choosing |
