- •Pads and battery are one Pad-Pak: the 350P combines both into a single cartridge with a four-year life, one part to track, not two.
- •Compact and rugged (IP56): among the lightest AEDs, easy to mount or carry.
- •FDA-approved via PMA (P160008). See all HeartSine models or refurbished options.
Verdict: The HeartSine samaritan PAD 350P (listed at $1,411 by authorized US distributors, checked 2026-07-22) is among the lowest-priced FDA-approved (PMA P160008)[1] AEDs for homes and small sites. Choose the 350P if you want a shock button at the lowest price. Choose the 360P if you want fully automatic shock delivery. Choose the 450P if responders need real-time CPR rate feedback.
Decision shortcut
Buy the 350P for homes, churches and small offices where price decides and a trained-enough adult will push the shock button.
Skip it if your responders are untrained and hesitant: the fully automatic 360P removes the button decision, and the 450P adds live CPR rate feedback.

| 450P | $1,761 (2026 list, confirm current) | Semi-automatic | Real-time CPR rate advisor | One Pad-Pak |
All three run in the FDA PMA P160008 family. List prices are 2026 US authorized-distributor figures; confirm current price, stock and included supplies before ordering.
Who should buy the 350P, and who should not
The 350P is built for one buyer: the small site that wants a credible, FDA-approved AED at the lowest realistic entry price. That means homes with a cardiac-risk family member, churches, dental and small medical offices, small gyms, and single-location businesses with one or two trained adults on site. If that describes you, the 350P does the job without paying for features you will not use.
It also suits program managers standardizing on the HeartSine brand across several small locations. One consumable part number per device keeps reordering simple, and the 2.4 lb weight (per the spec table below) makes it easy to wall-mount anywhere. Budget buyers should also know that refurbished 350P units exist on the secondary market; our guide to buying refurbished AEDs covers what to verify, starting with a documented recertification, a fresh Pad-Pak and a written warranty from the reseller.
Avoid the 350P if any of these apply
Your likely responders are untrained strangers. A semi-automatic device asks someone to press a shock button under stress. The fully automatic 360P removes that decision for $100 less at 2026 list.
You run a trained response team. Teams that drill regularly get more value from real-time CPR feedback, which the 350P does not offer. Look at the 450P or the ZOLL AED Plus covered below.
You manage a large, distributed fleet. The base 350P has no built-in Wi-Fi monitoring, so readiness checks are manual unless you add HeartSine’s separate Gateway accessory.
What the Pad-Pak system means for your budget
Most AEDs make you track two consumables on two schedules: electrode pads that typically expire in 2 to 5 years and a battery on its own separate clock. HeartSine combines both into one cartridge called the Pad-Pak, with a single expiration date of roughly 4 years from the date of manufacture per HeartSine documentation[2]. One part, one date, one replacement event.
A replacement adult Pad-Pak runs about $169 (typical 2026 US price, confirm current with your seller). That single figure is your entire scheduled maintenance cost for roughly four years. There is no separate battery purchase, and no risk of replacing pads while forgetting an aging battery.
Five-year cost of ownership (calculation, not a quote)
$1,411 device (checked 2026-07-22) + one Pad-Pak replacement at ~$169 = ~$1,464 through year five.
Stretched across the device’s 8-year warranty life with a second Pad-Pak replacement: $1,411 + ~$338 = ~$1,633, or about $204 per year.
Assumptions: the Pad-Pak included at purchase lasts ~4 years, no rescue deployments (a used Pad-Pak must be replaced), and the ~$169 typical 2026 price holds. Cabinets, signage and training are extra.
The tradeoff is worth naming. When a Pad-Pak expires, you replace the battery too, even though the battery cell itself might have had life left. In practice the simplicity usually wins for small sites, because the most common AED readiness failure is an expired consumable nobody tracked, and the Pad-Pak gives you exactly one date to track.
How the 350P works in a rescue
Press the green power button and the 350P starts talking immediately. Voice prompts paired with flashing icon lights walk the responder through pulling the tab, exposing the chest and attaching the two adhesive pads. The pads and battery are already connected inside the Pad-Pak, so there is no cable to plug in under stress.
The device then analyzes the heart rhythm on its own. If it detects a shockable rhythm, it charges and instructs the responder to stand clear and press the flashing orange shock button; if the rhythm is not shockable, the button stays locked out and no shock can be delivered by accident. That is the semi-automatic workflow: the machine makes the medical decision, the human only confirms the timing.
Between shocks, the 350P coaches CPR with voice prompts and a metronome-style beat to pace compressions. It does not measure compression depth, so it cannot tell a responder to push harder; that feedback tier starts with the 450P and the ZOLL AED Plus. The American Heart Association reports that immediate bystander CPR can double or triple survival odds from cardiac arrest[4], which is why even metronome-level coaching matters for untrained responders.
This rescue workflow is shared across the whole samaritan PAD line, which is one reason the family tests well with occasional responders; our HeartSine family review covers the shared platform in depth. The 350P also carries an IP56 dust and water resistance rating (see the spec table below)[2], which is higher than the IP21 rating Philips publishes for the OnSite and the IP55 rating ZOLL publishes for the AED Plus. For outdoor sites, pools and workshops, that rating difference is a practical advantage, not a spec-sheet footnote.

How does the 350P compare with other budget AEDs?
The two devices most 350P shoppers cross-shop are the Philips HeartStart OnSite and the ZOLL AED Plus. All three are FDA-approved through the PMA process, so the differences are price, consumables and CPR feedback, not regulatory status.
The Philips OnSite lists at $1,589 (2026 US list, confirm current), about $234 more than the 350P. Its distinguishing feature is availability without a prescription in the US, which removes one step for home buyers, and it uses separate pads and battery on separate expiration schedules. Our full Philips HeartStart OnSite review breaks down whether that convenience is worth the premium.
The ZOLL AED Plus lists at $2,082 (2026 US list, confirm current), roughly $726 above the 350P. That premium buys Real CPR Help, which measures actual compression depth and rate and coaches the responder to correct both in real time. If your site has trained responders who will drill with the device, read our ZOLL AED review before deciding; if your realistic responder is a family member or coworker who took one CPR class years ago, the 350P’s simpler prompts and lower price are the more defensible spend.
| Device | 2026 list price | Consumables | CPR feedback |
|---|---|---|---|
| HeartSine 350P | $1,411 (checked 2026-07-22) | One Pad-Pak, one date | Metronome-level prompts |
| Philips OnSite | $1,589 (2026 list, confirm current) | Separate pads and battery | Voice coaching, no depth measurement |
| ZOLL AED Plus | $2,082 (2026 list, confirm current) | Separate pads and batteries | Real-time depth and rate feedback |
FAQs
Is the HeartSine 350P FDA approved?
Yes. The HeartSine samaritan PAD family holds FDA premarket approval under PMA P160008[1], the agency’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[1]. 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. Price-wise at 2026 list, the 360P is the cheapest at $1,195, the 350P sits at $1,411, and the 450P tops the line at $1,761 (confirm current).
How much does Pad-Pak replacement cost?
A replacement adult Pad-Pak typically costs about $169 in the US (typical 2026 price, confirm current with your seller). Because it contains both the pads and the battery, that is the only scheduled consumable purchase, due roughly every 4 years.
Can the 350P be used on children?
Yes, with the separate pediatric Pad-Pak (Pad-Pak-02 or Pad-Pak-04), which drops the shock energy to 50 J per the specifications above[2]. HeartSine documentation indicates the pediatric Pad-Pak is intended for young children below the adult pad threshold; check current labeling requirements and any prescription conditions with the seller before ordering.
What warranty does it have?
HeartSine, a Stryker company, backs the 350P with an 8-year manufacturer warranty per HeartSine and Stryker documentation[3]. That is one of the longer standard warranties in the AED market, and it applies to new units bought from authorized distributors, so keep your proof of purchase.
Is it good for home use?
Yes, and home buyers are arguably its core market. The $1,411 entry price (checked 2026-07-22), the single 4-year consumable, the 2.4 lb weight and the simple voice-guided workflow all fit a household where one adult keeps an eye on one expiration date. Note that it is a prescription device in the US; distributors typically handle the physician authorization as part of the sale.
How often does it self-test?
The 350P runs an automatic self-check every week per HeartSine documentation[2], testing its circuitry and battery without any user action. A flashing green status indicator confirms readiness; if the indicator is not flashing green, the device needs attention. Your only manual job is a periodic glance at that light and the Pad-Pak date.
The bottom line
The HeartSine samaritan PAD 350P earns its place as one of the lowest-priced FDA-approved AEDs you can put on a wall, and the single-date Pad-Pak makes it one of the easiest to actually keep rescue-ready. Its limits are honest ones: no shock automation, no compression depth feedback, no built-in fleet monitoring. If your site has at least one adult willing to press a button, roughly $1,464 through year five (our calculation above) buys a credible, PMA-approved response to cardiac arrest.
