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.
