HeartSine AED Review 2026: samaritan PAD 350P, 360P and 450P Verdict

Verdict: HeartSine, a Stryker company, makes the samaritan PAD family, three AEDs (350P, 360P, 450P) that share one platform, one FDA premarket approval (PMA P160008)^[1], one consumable (the Pad-Pak), and the highest ingress rating in mainstream consumer AEDs (IP56). Buy the 350P for the lowest-priced credible AED at a single site, the 360P if you want fully automatic shock delivery, and the 450P if responders need real-time CPR rate coaching. If you have already settled on the 350P, our full HeartSine samaritan PAD 350P review covers pricing, specs and the buyer checklist in depth.

What every HeartSine samaritan PAD shares

The three current models are the same AED at their core, which is the single most useful fact for a HeartSine buyer. All three hold FDA premarket approval under PMA P160008^[1], the agency’s most rigorous device pathway, and you can verify the record in the FDA database linked in the references below. All three use the same SCOPE biphasic waveform, the same voice-and-visual prompting, and the same Pad-Pak cartridge. The differences between them are narrow and specific, so you are choosing a coaching tier and a shock mode, not a different level of safety.

That shared platform is why the family tests well with occasional responders and why standardizing a small multi-site program on HeartSine keeps reordering simple: one consumable part number covers every device you own. HeartSine also backs the line with an 8-year manufacturer warranty per HeartSine and Stryker documentation^[3], one of the longer standard warranties in the AED market.

The three current models, compared

Two things stand out. The fully automatic 360P is actually the cheapest of the three at 2026 list, which makes it the value pick when your likely responder is a stranger who should not be asked to press a shock button under stress. And the 450P is the only model in the family that coaches compression rate, though even it does not measure compression depth; that depth-feedback tier starts with the ZOLL AED Plus, covered below.

The Pad-Pak: one consumable, one date

Most AEDs make you track two consumables on two clocks: electrode pads that expire in roughly 2 to 5 years and a battery on a separate schedule. HeartSine combines both into a single cartridge, the Pad-Pak, with one expiration date of about 4 years from manufacture per HeartSine documentation^[2]. One part, one date, one replacement event. Because the most common AED readiness failure is an expired consumable nobody was tracking, collapsing two dates into one is a real operational advantage for a site without a dedicated safety officer.

The honest tradeoff: when a Pad-Pak expires you replace the battery too, even if the cell had life left. For a small site that simplicity usually wins. For a large distributed fleet it does not, because the base samaritan PAD has no built-in cellular monitoring, so readiness checks stay manual unless you add HeartSine’s separate Gateway accessory.

The IP56 advantage, and when it actually matters

HeartSine publishes an IP56 ingress rating across the samaritan PAD line, the highest among mainstream consumer AEDs. Under the IEC 60529 standard, IP56 means dust-protected plus protection against powerful water jets from any direction^[4]. For comparison, Philips and ZOLL publish IP55 for their consumer models, and the Defibtech Lifeline is rated IPX4. Our guide to AED IP ratings explains what each digit means in plain terms.

Be honest about when this is decisive. For a lobby cabinet or an office wall, IP55 and IP56 are functionally equivalent and should not swing your decision. Where the extra rating earns its keep is sustained outdoor exposure: sports sidelines, marina docks, agricultural and construction sites, anywhere a device faces weather year-round. In those settings the 450P plus a weatherproof outdoor cabinet is a defensible spec, and the IP56 rating is a reason to shortlist HeartSine rather than a spec-sheet footnote.

What HeartSine does not do, and what to buy instead

No AED family fits every buyer. Here is where the samaritan PAD line hands the win to a competitor, stated plainly so you do not discover the gap after purchase.

Frequently asked questions

Is the HeartSine samaritan PAD FDA approved?

Yes. The entire samaritan PAD family (350P, 360P, 450P) holds FDA premarket approval under PMA P160008^[1], the FDA’s most rigorous device pathway. You can verify the record directly in the FDA’s PMA database, linked in the references below.

What is the difference between the 350P, 360P and 450P?

All three share the same platform, waveform, Pad-Pak consumable and PMA P160008 approval. The 350P is semi-automatic with a shock button, the 360P delivers the shock fully automatically with no button press, and the 450P is semi-automatic with a real-time CPR rate advisor added. At 2026 list the 360P is cheapest at $1,195, the 350P sits at $1,295, and the 450P tops the line at $1,535 (confirm current).

Our Find Your Perfect AED quiz maps these three configurations to your likely responders in about a minute.

Which HeartSine is best for home use?

For most homes the 350P is the core pick: lowest credible price, one 4-year consumable, and a 2.4 lb weight that mounts anywhere. If the likely responder is a family member who has never taken a CPR class, the fully automatic 360P removes the shock-button decision for $100 less. Our 350P review walks through the home-buyer math in detail.

Are HeartSine AEDs weatherproof?

The samaritan PAD line carries an IP56 rating under IEC 60529, dust-protected and resistant to powerful water jets, the highest in mainstream consumer AEDs. For sustained outdoor deployment, pair the device with a weatherproof, temperature-controlled outdoor cabinet; the rating protects the device, but battery and pad performance still depend on staying within the manufacturer’s temperature range.

How much does a HeartSine cost to own over five years?

For the 350P, roughly $1,464 through year five: the $1,295 device (checked 2026-07-22) plus one adult Pad-Pak replacement at about $169. The 360P and 450P use the same Pad-Pak, so their five-year totals differ only by the device price. These are calculations from typical 2026 prices, not quotes; confirm current pricing with your seller.

Can HeartSine AEDs be used on children?

Yes, with the separate pediatric Pad-Pak (Pad-Pak-02 or Pad-Pak-04), which lowers the delivered energy for young children. Check current labeling and any prescription conditions with the seller before ordering, since AEDs are prescription devices in the US.

Facilities serving children should also read our AEDs for schools guide, which covers pediatric pad requirements and placement.

The bottom line

HeartSine’s value is a genuinely shared platform: one FDA approval, one consumable, one warranty, and the highest ingress rating in the consumer category, across three models that differ only in shock mode and CPR coaching. That makes the buying decision unusually clean. Pick the 350P for the lowest-priced credible single-site AED, the 360P when an untrained responder should not face a shock-button decision, and the 450P for trained or outdoor programs that want rate coaching. Step outside the family only when you need compression-depth feedback or cellular fleet monitoring.
