HeartSine Samaritan PAD 450P

The CPR Rate Advisor is a built-in metronome that audibly guides chest compressions at the AHA-recommended 100–120 per minute. The 450P’s voice prompts coach rate timing only, unlike ZOLL’s Real CPR Help, it does not measure compression depth. For trained athletic staff, this is less than Real CPR Help offers. For untrained school staff who have never run a rescue, rate guidance alone is a meaningful improvement over voice-only timing. It’s the right middle-ground feature for K-12 facilities at the $1,761 price point.

Spend the $350 only if your school staff is untrained and you want CPR rate guidance built into the device. Both share the same Pad-Pak workflow and 8-year warranty, so accessory standardization is identical. The 450P’s CPR Rate Advisor metronome helps untrained staff hit the right compression timing. For schools with athletic trainers or anyone formally CPR-trained, the 350P at $1,411 delivers the same rescue capability minus the rate guidance. For mandate-state K-12 districts buying at scale, the 450P’s added confidence often justifies the upgrade.

The 450P ships with both an Adult Pad-Pak and a Pediatric Pad-Pak, which is the capability most state K-12 AED statutes ask for. State requirements differ on placement, registration, staff training and inspection cadence, and they change from session to session, so treat this as a starting point and not a compliance ruling. Check the current rules in our AED laws by state tracker, then confirm against your state education department current approved-vendor list before procurement.

Open the cabinet, eject the gray Adult Pad-Pak by pressing the release tab, and slide in the pink Pediatric Pad-Pak. The whole swap takes about 5 seconds. The device automatically detects the pediatric cartridge and adjusts both pad geometry and shock energy. The pink visual coding is deliberate. During a panicked rescue with a child patient, the color cue prevents wrong-SKU errors that affect every other AED’s pediatric workflow. Stock both cartridges side-by-side in any cabinet serving mixed-age populations.

The American Heart Association recommends placement so that any cardiac arrest victim can have an AED applied within 3 minutes from collapse, which is roughly a 1.5-minute round-trip walk from any classroom. For a typical 50,000 sq ft elementary school, that’s usually 2–3 AEDs (main entrance, gym, cafeteria). High schools with athletic fields and multiple wings often need 5–8 units. Use our AED Quantity Calculator with your floor plan to get a precise number based on actual cabinet locations and travel times.

Yes. The Adult Pad-Pak 01 and Pediatric Pad-Pak work identically across the 350P, 360P, and 450P. That’s a deliberate HeartSine design choice: a district running mixed-model fleets only needs to stock two cartridge SKUs total. The 450P’s CPR Rate Advisor is in the device itself, not the cartridge, so swapping in a 350P-grade Pad-Pak doesn’t degrade the rate-guidance feature. This accessory standardization makes HeartSine the easiest brand for multi-AED procurement in the school category.
