Samaritan PAD 360P

Public Access · Fully Automatic · High-Traffic Spaces
$1,651

The HeartSine Samaritan PAD 360P is the fully automatic version of the 350P, identical in form factor and weight, but it delivers a shock via a verbal 3-2-1 countdown without requiring the rescuer to press any button.

Public Access · CPR Rate Coaching · Trained Responders
$1,761

The HeartSine Samaritan PAD 450P adds a CPR Rate Advisor to the Samaritan platform, the only AED in its weight class to offer real-time compression rate coaching. A traffic light LED array (green/amber/red) gives visual rate feedback alongside verbal cues: push faster, push slower, or good speed. This makes it the strongest choice for organizations that want active CPR guidance without sacrificing the compact, lightweight form factor the Samaritan line is known for. It remains semi-automatic, requiring a shock button press.

Recommended AEDs by Use Case

Schools & Universities

Prioritize simplicity for untrained bystanders and pediatric capability with lightweight devices that can be deployed throughout a building. Fully automatic options reduce hesitation.

Multi-Site & Enterprise Programs

Cellular connectivity and remote monitoring are essential when you can't physically check devices across multiple locations. GPS tracking confirms devices stay where they belong.

First Responders & Harsh Environments

Drop resistance, crush resistance, extreme temperature operation, and military-grade durability are non-negotiable.

Healthcare & Clinical Settings

ECG display, non-diagnostic monitoring, and advanced CPR feedback matter when trained staff are the primary responders. Video guidance reinforces technique under pressure.

Home & Personal Use

FDA OTC designation with no prescription required, and designed for people who have never used an AED. Ready to use immediately out of the box.

Travel, Sports & Compact Deployment

Weight and form factor are the deciding factors. The HeartSine Samaritan line at 2.4 lbs with IP56 protection fits in a bag, a cabinet, a vehicle, or a wall mount in tight spaces.

Compliance-Focused & Low-Maintenance Programs

Remote monitoring, long warranties, and low total cost of ownership reduce program overhead. Built-in connectivity keeps device status current without manual checks, and the 350P's single Pad-Pak expiry date simplifies replacement tracking.

Important:

Owning an AED is not the same as being prepared to use one. A complete AED readiness program includes regular inspections, on-schedule pad and battery replacement, staff training, and compliance documentation.

Frequently Asked Questions

What is the lightest AED available?

The HeartSine Samaritan PAD 350P, 360P, and 450P are the lightest AEDs available at 2.4 lbs (1.1 kg). They also carry an IP56 rating, the highest dust and water protection available in a portable AED.

Which AED has the best CPR feedback?

The ZOLL AED Plus and ZOLL AED 3 are the only AEDs that provide real-time feedback on both compression depth and rate through Real CPR Help technology. The HeartSine 450P adds verbal and visual rate coaching (push faster/slower/good speed) without depth monitoring. Most other AEDs provide rate feedback only via metronome.

Which AED has cellular connectivity?

The LIFEPAK CR2 Cellular has built-in 4G LTE with GPS tracking and 24/7 LIFELINKcentral monitoring, no local Wi-Fi required. The ZOLL AED 3 supports cellular connectivity via the separately purchased ZOLL AEDTrax.

Do I need a prescription to buy an AED?

Most AEDs require a prescription. The Food and Drug Administration regulates AEDs as Class III medical devices, so a prescription is required. When you acquire an AED through AED.US, a prescription is issued that meets the medical authorization required by the FDA.

Which AED is best for schools?

For schools, the ZOLL AED 3, LIFEPAK CR2, or Philips OnSite are strong choices. All provide clear voice guidance for untrained bystanders, include pediatric pad options, and are lightweight enough for multi-point wall deployment throughout a building.

Which AED is best for outdoor or harsh environments?

The Philips HeartStart FRx withstands 500kg crush force, 1.2-meter drops, and temperatures from -20°C to +50°C, the most rugged AED in this comparison. The HeartSine 350P/360P/450P also offer IP56 protection, the highest dust and water rating available in a portable AED.

What is the longest AED warranty?

The HeartSine Samaritan PAD 350P, 360P, and 450P carry a 10-year device warranty. The LIFEPAK CR2, Philips HeartStart OnSite, FRx, and Home, Cardiac Science G5 (with registration), and both Defibtech models carry 8-year warranties.

What's the difference between semi-automatic and fully automatic AEDs?

A semi-automatic AED analyzes the heart rhythm and charges, but requires the rescuer to press a button to deliver the shock if needed. A fully automatic AED delivers the shock after a verbal countdown with no button press required. Fully automatic AEDs are preferred for public deployment where bystander hesitation is a concern.

Do I need Wi-Fi connectivity in my AED?

Not necessarily, but remote monitoring reduces compliance gaps significantly for organizations managing multiple devices. Wi-Fi and cellular-connected AEDs automatically report readiness status, battery/pad expiration alerts, and post-event data to a central dashboard without manual inspection. For single-device or small programs, standalone AEDs with scheduled manual checks are sufficient.

Ready to Build a Complete AED Program?

Device ownership is the starting point. Ongoing readiness, training, and compliance management is what saves lives.
