HeartSine markets three AEDs in the Samaritan PAD line: the 350P (semi-automatic), 360P (fully automatic), and 450P (semi-automatic with CPR rate advisor). All three share the same lightweight 2.4 lb chassis, the same IP56 outdoor rating, the same 4-year combined Pad-Pak architecture, and the same 10-year device warranty. What differs is shock-delivery automation and CPR coaching.
Buyers usually arrive at this comparison after deciding HeartSine is the right brand — the lineup question is which configuration matches their operating environment. The price gap from cheapest to most expensive is roughly $500 ($995 to $1,495).
Quick answer
350P for single-AED budget buyers, schools, churches, and small businesses with trained or partially trained responders. 360P for fully-public-access deployments where the rescuer may be untrained — fully automatic eliminates shock-button hesitation. 450P for facilities with designated responders who want CPR rate coaching but not necessarily full Real CPR Help® depth measurement.

The 350P — lowest 5-year cost on the market
The HeartSine 350P at $995 retail is the cheapest FDA-cleared AED in the US market. With one $120 Pad-Pak replacement over 5 years and a $149 cabinet, the program totals $1,264 over 5 years — the lowest in the AED comparison set. The 2026 AED Best Brands Best Budget award sits on this device.
The trade-offs: semi-automatic only (shock-button hesitation risk in untrained rescuers), voice prompts only (no CPR coaching), and a separate Pediatric Pad-Pak required for child rescue. For schools and small businesses with trained or partially-trained responders, those trade-offs are acceptable. For lay-public-access deployments, they are not.
The 360P — fully automatic plus auto-detect pediatric
The 360P is the only HeartSine device with fully automatic shock delivery. Combined with auto-detect pediatric (no separate Pad-Pak required for child rescue), the 360P is the lay-public-access pick in the HeartSine lineup.
The auto-detect feature works through the Pad-Pak’s built-in sensors — the device estimates patient size from pad impedance and adjusts shock energy accordingly. This is not as clean as the LIFEPAK CR2’s button-based child mode or the FRx’s Infant/Child Key, but for facilities that prefer one-pad-set simplicity, the 360P removes the swap workflow.
The 450P — CPR rate advisor adds coaching
The 450P adds a visual CPR rate advisor — a flashing icon that shows the rescuer the target compression rate (100-120 BPM per AHA guidelines). This is rate coaching only, not depth coaching. ZOLL devices provide both depth + rate coaching; HeartSine’s 450P provides rate only.
For facilities with designated responders who want some CPR coaching but not the premium ZOLL price, the 450P is a middle option. Trade-off: $300 premium over the 350P for what is genuinely a less comprehensive coaching feature than what ZOLL offers.
Pad-Pak economics across the lineup
All three devices use the same Pad-Pak architecture: a single combined cartridge that includes both the electrode pads and the battery, with a 4-year shelf life. Buyers track one expiration date for the consumables. Replacement is one purchase every 4 years.
The Pad-Pak cost differs slightly across the three devices — 350P at $120, 360P at $130, 450P at $170 — reflecting the additional sensors in the higher-tier units. Pediatric Pad-Pak costs roughly $170 across all three.
Real-world deployment scenarios
Scenario A — small Baptist church, 250 members, single deacon trained in CPR
Budget-conscious. Adult congregation. One trained responder. Recommendation: HeartSine 350P. $995 retail. The deacon’s training covers semi-automatic shock-button workflow. No pediatric requirement (no childcare program). 5-year total ~$1,264 — fits a small church budget.
Scenario B — community recreation center, lobby AED, untrained volunteer staff
Public access. Volunteer-staffed front desk. High turnover. Mixed adult + occasional child program. Recommendation: HeartSine 360P. Fully automatic removes shock-button hesitation. Auto-detect pediatric covers occasional child use. IP56 supports an outdoor pool deck if expanded.
Scenario C — 80-employee manufacturing shop, 1 AED, on-staff safety manager certified in CPR
Trained responder. Industrial floor environment. The safety manager wants CPR coaching but not full ZOLL premium. Recommendation: HeartSine 450P. CPR rate advisor + IP56 dust-and-water rating + lightweight 2.4 lb chassis match a shop-floor wall-mount deployment.

Frequently asked questions
Are all three FDA-cleared?
Yes. All three hold current 510(k) clearance. Verify in the FDA database before purchase.
Which has the lowest 5-year cost?
The 350P at roughly $1,264 over 5 years, including one Pad-Pak replacement and a cabinet.
Are the Pad-Paks interchangeable across the three models?
No. Each model uses a model-specific Pad-Pak (different sensors in the 450P and 360P). Buy the correct Pad-Pak for the device.
Which one is the lightest?
All three weigh 2.4 lb / 1.1 kg — the lightest FDA-cleared AED chassis on the market.
Does the 450P provide depth-of-compression coaching?
No. The 450P provides rate coaching only (visual icon showing target BPM). For depth + rate coaching, the ZOLL AED Plus or ZOLL AED 3 is the correct pick.
Which is the right choice for outdoor sports fields?
The 360P (fully automatic) for lay-rescuer environments, or the 450P (with CPR coaching) for designated-responder programs. All three carry IP56, suitable for outdoor deployment with cabinet protection.
