Sports-related cardiac arrest accounts for 39% of all sudden cardiac arrests in people 18 and under. Here's what actually matters when choosing an AED for a K-12 campus.
For most schools: a device with a universal or simplified pediatric mechanism (no pad-swapping under pressure), CPR feedback for non-medical staff, and an IP55 or higher rating for gym and outdoor storage.
Our top pick is the HeartSine Samaritan PAD 450P, but the right choice depends on your specific campus. See all five below.
Do Schools Actually Need to Care About This?
Only 15.9% of children who experience out-of-hospital cardiac arrest and are treated by EMS survive to hospital discharge, per the American Heart Association's own 2025 data. Speed to defibrillation is the single biggest lever a school controls.
There's no federal law requiring AEDs in schools. More than 20 states require them anyway, and several more require them specifically for school athletic events even without a general mandate.
Requirements change often; verify your own state's current law rather than assuming.
Some states extend liability protection to good-faith AED use only if your program meets specific statutory requirements (training, EMS registration, regular maintenance), not just from owning a device.
Confirm what your state actually requires to be protected, not just to be compliant.
Placement and Funding
A common planning standard: place AEDs so any point on campus can be reached and a responder can return within one to three minutes. Larger or multi-building campuses typically need more than one unit.
Real grant funding exists specifically for schools. Hopey's Heart Foundation provides free AEDs to qualifying 501(c)(3) organizations and government entities, explicitly including public schools and school districts.
The Firehouse Subs Public Safety Foundation funds life-saving equipment for public safety and community organizations.
Civic organizations, Rotary, Lions, Elks, VFW, American Legion, are also common, accessible funding sources for a single-device request. Availability and terms change; confirm current eligibility directly with each program.
The Top 5, and Why
Ranked specifically for the school use case: mixed ages from kindergarten through varsity athletics, non-medical staff as primary responders, and equipment that may live in a gym, athletic shed, or high-traffic hallway.
HeartSine Samaritan PAD 450P
The highest IP rating in our full comparison (IP56), real-time CPR rate feedback for staff without recent training, and one of the lightest AEDs available at 2.4 lbs.
Physio-Control LIFEPAK CR2
One electrode set treats every age from kindergarten to varsity athlete; a Child Mode button switches therapy without swapping pads under pressure. Built-in cprINSIGHT and cprCOACH feedback, WiFi-based remote monitoring reduces manual daily checks.
ZOLL AED 3
Real CPR Help measures both compression depth and rate, a color touchscreen adds visual guidance for noisy gyms, and the universal CPR Uni-padz electrode handles adult and pediatric patients from one set of pads.
Cardiac Science Powerheart G5
Rescue Ready self-testing runs daily, weekly, and monthly checks automatically, meaningfully reducing the manual-inspection burden on school staff. With the iCPR pad variant, it also measures compression depth, rate, and chest recoil together.
Philips HeartStart FRx
The Infant/Child Key converts the same adult pads for pediatric use with no swap required, and its IP55 rating suits gym and athletic storage. Note: it does not offer real-time CPR depth or rate feedback, voice and visual step-by-step guidance only.
Both are excellent devices, but both carry an IP21 rating, rated for indoor drips only, not the gym, field house, or athletic shed many schools also need to cover. The FRx above gets Philips' same ease of use with a rating suited to the whole campus.
Frequently Asked Questions
What is the best AED for a school setting?
Depends on your specific campus, but the strongest general fit combines a universal or simplified pediatric mechanism, CPR feedback for non-medical staff, and an IP55 or higher rating. See our full top 5 above.
How many AEDs are required in a school building?
There's no universal number. The common planning standard is to place units so any point on campus can be reached and a responder can return within one to three minutes. Larger or multi-building campuses typically need more than one.
Does federal law require AEDs in schools?
No. There's no federal mandate. More than 20 states require them by statute, and additional states require them specifically for school athletic events. Verify your own state's current requirement directly, since this changes frequently.
What is the average cost of an AED for a school?
Most current models run in the $1,500 to $2,400 range for a complete package, depending on brand and included accessories. Call (855) 286-6384 for current pricing on any of the five models above.
Which AED is easiest for teachers and students to use?
All five recommendations above are built for untrained responders, with step-by-step voice guidance. Devices with CPR feedback (all except the FRx) offer an additional layer of real-time correction that particularly benefits people without recent CPR training.
Do schools need pediatric pads for their AEDs?
Yes, if the campus serves anyone under 8 years old or under 55 lbs. Elementary and K-8 schools need this without question; high-school-only campuses with no younger visitors may not.
Will this AED work for both a first-grader and a high school football player without swapping pads?
With the LIFEPAK CR2, ZOLL AED 3, or Philips FRx, yes, all three use one electrode set with a mode switch instead of separate pediatric pads. The HeartSine and Cardiac Science models in our top 5 use separate pediatric pad cartridges instead.
How much will we have to spend on replacement batteries and pads over the next five years?
Varies by brand and shelf life, generally one to two pad replacements and one battery replacement within a 5-year window across the models above.
See our full AED total cost of ownership breakdown for exact figures by brand.
If a teacher uses the device, are we legally protected from liability in this state?
Most states extend some Good Samaritan or AED-specific protection to good-faith use, but the details vary significantly.
Some states condition that protection on meeting specific program requirements, training, registration, maintenance, not just owning a device.
This isn't legal advice; confirm your specific state's requirements with your district's legal counsel before assuming coverage.
Does the device perform self-tests so we don't have to manually check it every day?
Yes, all five recommendations run automatic self-tests. The Cardiac Science Powerheart G5's Rescue Ready system is the most extensive, with daily, weekly, and monthly automated checks specifically built to reduce manual staff burden.
Can the AED be heard clearly in a noisy gymnasium or cafeteria during an emergency?
We don't have decibel-tested data for gym or cafeteria noise specifically on any of these five models.
What we can tell you: the ZOLL AED 3's color touchscreen and HeartSine's LED display both pair visual guidance with voice, specifically so instructions remain usable if audio alone is hard to hear.
Are there grants available specifically for public schools to offset the initial purchase cost?
Yes. Hopey's Heart Foundation explicitly includes public schools and school districts as eligible recipients for a free AED. The Firehouse Subs Public Safety Foundation and local civic organizations (Rotary, Lions, Elks, VFW) are also common funding sources.
Confirm current eligibility and award timelines directly with each program before applying.
How long is the manufacturer's warranty, and what happens if the device fails a self-test?
All five recommendations above carry an 8-year manufacturer warranty. A failed self-test typically displays a service indicator; stop using the device for a rescue and contact the manufacturer or Total AEDs immediately rather than attempting a repair yourself.
See our full AED warranty comparison for brand-by-brand terms.
Is the device durable enough to be kept in an outdoor athletic equipment shed?
The HeartSine (IP56), LIFEPAK CR2, ZOLL AED 3, Cardiac Science G5, and Philips FRx (all IP55) in our top 5 are all built for this. The Philips OnSite and Home are not; their IP21 rating covers indoor drips only.
See our full AED IP ratings comparison for the complete picture.
