HeartSine offers three Samaritan PAD models in the refurbished market. They share the same chassis, same Pad-Pak system, same IP56 rating, same weight, same waveform. Differences come down to two binary choices: shock delivery (semi-auto vs fully-auto) and CPR feedback (none vs Rate Advisor). The 350P is the simplest, lowest-priced option — making no compromises on physical specifications but skipping both operational upgrades.
Choose the 350P when budget is your primary consideration and your facility has trained responders who are comfortable with traditional semi-automatic AED operation. Step up to the 360P when untrained bystanders are the most likely first responders the fully automatic shock delivery eliminates one decision under stress. Step up to the 450P when real-time CPR rate coaching matters for your responder profile, particularly environments with high responder turnover or volunteer rescue programs.
Same Physical Excellence, Lowest Refurbished Price
The 350P doesn't compromise on the things that distinguish the HeartSine line it's just as small, just as light, just as rugged, just as well-engineered as the 360P and 450P. The difference is operational features the 350P doesn't include, not physical quality the 350P gives up.
Practically, this means a 350P buyer gets the same 2.4-pound compact AED with the same IP56 rating and the same Pad-Pak unified consumable system that makes HeartSine programs distinctively simple to maintain. The only trade-off is the older semi-automatic operation model which is genuinely a non-issue for facilities with trained responders who know how to press a shock button.
Two-Button OperationOn/off and shock the industry-standard interface that every CPR/AED training course teaches. Trained responders will recognize and operate the 350P immediately without device-specific training.
Among the Lightest AEDsAt just 2.4 pounds, the 350P is one of the smallest and lightest AEDs available. Compact enough for vehicle storage, athletic kits, marine deployments, and tight installations where every ounce and inch matters.
IP56 Industry-Leading RatingThe IP56 rating exceeds the IP55 rating of most competitive AEDs. Designed for industrial, outdoor, marine, and other environments where dust and water resistance matter — not just clean indoor lobbies.
Pad-Pak Unified CartridgeSingle cartridge with combined battery + adult electrodes + one shared 4-year expiration date. One item to track, one item to replace. Over 4 years: one Pad-Pak vs one battery and two separate pad replacements on competing AEDs.
SCOPE Biphasic WaveformHeartSine's proprietary Self-Compensating Output Pulse Envelope an escalating, low-energy biphasic waveform that automatically adjusts for patient impedance, delivering effective therapy while minimizing energy exposure.
Voice + Visual + MetronomeStep-by-step voice instructions with synchronized visual diagrams and an integrated CPR metronome that paces compressions to the AHA-recommended 100–120 BPM. Coaches CPR rate even without real-time feedback.
Weekly Self-TestsAutomatic weekly self-checks of battery voltage, internal electronics, and electrode connection. The System Status Ready Indicator on the front of the device flashes when ready visible without opening the unit.
LIFELINKcentral Compatible (WiFi Variant)The WiFi-equipped variant connects to HeartSine's LIFELINKcentral cloud platform for automated weekly self-test reporting and remote device readiness monitoring. Basic monitoring features available when connected; advanced multi-device fleet features may require subscription.
Compact 8.0 × 7.25 × 1.9 Inch FootprintUp to 56% smaller footprint than other compact AEDs fits into spaces other AEDs can't. Suitable for small office desk drawers, aircraft galley compartments, vehicle glove boxes, or other tight installations.
