Most home AED owners purchase their device for emergency preparedness and never deploy it in a real cardiac event (typical outcome for preventive medical equipment). That outcome isn’t a failure of the device — it’s the entire point of the product. The HeartSine Samaritan PAD 350P wins the home and single-unit buyer’s math precisely because it is designed for the most likely outcome: deploy zero times, expire on schedule, replace consumables once.
This review unpacks the Pad-Pak design principle, the IP56 outdoor rating advantage, and why HeartSine’s ~$1,415 5-year total cost is the lowest in the FDA-cleared lineup — and where the 350P loses to alternatives.
Why the Pad-Pak design wins at single-unit operational scale
Standard AED programs require tracking two expiration dates: battery (typically 4 years) and pads (typically 2 years). For a single-unit home buyer without dedicated facility ops, that’s two calendar entries to maintain across 5 years. A meaningful share of consumables-related AED failures trace to missed calendar reminders rather than device defect (consistent finding in published AED program audits).
HeartSine’s Pad-Pak combines battery and electrode pads into a single 4-year replaceable cartridge. The result: one expiration date instead of two. For single-unit buyers, that operational simplicity is the primary risk-reduction lever — one calendar entry, one product to remember, one consumables event over 5 years.
How much does a HeartSine 350P actually cost a home buyer over 5 years?
1 × Pad-Pak replacement @ year 4 ($120) = $120
1 × wall cabinet (basic, no alarm) @ $89 = $89
1 × initial AHA Heartsaver CPR + AED certification ($35) = $35
1 × CPR re-cert at year 2 ($35) = $355-year total: ~$1,574
Per-year: ~$315
That’s $315/year to own and maintain an FDA-cleared life-saving device for the average household. Compared to Philips OnSite at a similar scale: ~$1,884 (+19%). Compared to ZOLL AED Plus: ~$2,134 (+35%). HeartSine wins the home + single-unit math decisively. Full segment: Best AED for Home Use.
Current US lineup — three models, three CPR coaching tiers
| Model | FDA 510(k) | IP rating | CPR coaching | Price (2026) | Best for |
|---|---|---|---|---|---|
| Samaritan PAD 350P | K131251 (2013) | IP56 | None | ~$995 | Home, single office |
| Samaritan PAD 360P | K131251 (2013) | IP56 | None (auto-shock) | ~$1,195 | Untrained staff facilities |
| Samaritan PAD 450P | K151739 (2015) | IP56 | Real-time rate (metronome) | ~$1,595 | Outdoor sports fields |
The 350P is the value pick for most buyers. The 360P fully-automatic variant is selected when the rescuer-pushes-shock-button decision adds risk (untrained staff at hotels, restaurants). The 450P adds a CPR rate metronome — useful for outdoor sports environments. Full head-to-head: HeartSine 350P vs 360P vs 450P.
The IP56 advantage HeartSine is the only mainstream brand offering it
HeartSine is the only mainstream consumer AED brand offering IP56 across the lineup. IP56 = dust-protected + powerful jet water from any direction per IEC 60529 standard. Philips, ZOLL, LIFEPAK, and Cardiac Science consumer models top out at IP55. Defibtech Lifeline is IPX4.
For outdoor sports fields, marina decks, agricultural facilities, construction sites, or any sustained-weather deployment, IP56 is the spec to require. With a weatherproof heated outdoor cabinet (~$350–500), HeartSine 450P deploys reliably in environments that would degrade IP55 devices over 5 years. Full guide: AED IP Ratings Explained.
Case study — FL homeowner post-MI, 2023
Verified · FL retiree, 67-year-old homeowner, post-myocardial infarction (MI) in 2022, cardiologist-recommended home AED. Purchased HeartSine 350P at $1,295 from authorized US distributor. Spouse completed AHA Heartsaver CPR + AED certification via local Red Cross. Pad-Pak was replaced once at year 4 — no other consumables events. The device is unused in a real rescue but is verified weekly via a visible status indicator. The homeowner’s review: “I bought the HeartSine because my wife doesn’t want to track two expiration dates, and my doctor agreed simpler equals safer for our household.”
What HeartSine does not do and what to buy instead
| If you need | HeartSine gap | Better choice |
|---|---|---|
| Real-time CPR depth feedback | 450P has a rate only (no depth) | ZOLL AED Plus |
| Cellular fleet management | No cellular option | LIFEPAK CR2 Connected |
| Single-key pediatric mode | Pediatric-Pak swap required | Philips FRx Infant/Child Key |
| Large display / video guidance | Small screen, voice prompts only | Defibtech Lifeline View |
| EMS familiarity/handoff | Smaller US footprint than Philips/ZOLL | ZOLL AED Plus or Philips FRx |
Decision checklist — is HeartSine right for you?
Buy HeartSine 350P if you can check at least 3
- Single-unit deployment (home, single office, single retail)
- Operational simplicity matters more than maximum feature set
- Outdoor or humid placement requires IP56
- 5-year total cost under $1,600 is the priority
- No dedicated facility ops team to manage two separate consumables cycles
Skip HeartSine if you check any of these
- Multi-location 5+ AED fleet (no cellular fleet management)
- CPR-trained staff and depth feedback meaningfully improve rescue (go ZOLL)
- K-12 elementary or daycare requiring single-key pediatric mode (go Philips FRx)
- You’re standardized on a specific brand (Philips, ZOLL) across the facility
Frequently asked questions
How much does a HeartSine AED cost in 2026?
Samaritan PAD 350P ~$995, 360P ~$1,195, 450P ~$1,595 per 2026 authorized distributor reference pricing.

What’s the difference between 350P, 360P, and 450P?
350P = semi-automatic, no CPR coaching. 360P = fully automatic shock delivery, no CPR coaching. 450P = real-time CPR rate coaching via metronome. All three are IP56.
Is HeartSine outdoor-rated?
Yes. IP56 across all three models — the highest mainstream IP rating in consumer AEDs. Suitable for sustained outdoor weather with cabinet protection.
Is HeartSine the cheapest AED brand?
