What the AI looks for in Medical Defibrillators
- FDA approval
- In the US, buy only an AED with current FDA premarket approval (PMA), which has been required for AEDs since 2015. Older 510(k)-only models and gray-market imports may no longer be supported or legally supplied with consumables.
- Pediatric capability
- The unit should support pediatric pads or a child mode for children under 8 years or about 25 kg / 55 lb. Adult energy levels are not appropriate for small children, and households and schools often need both.
- Consumable shelf life and availability
- Check the expiration interval of the battery and pads and that replacements are readily available for the model. An AED with expired pads or battery may fail when needed. Ongoing consumables matter more than the unit itself.
- Semi-automatic vs fully automatic
- Fully automatic units deliver the shock themselves. Semi-automatic units require the rescuer to press a button. Fully automatic models remove hesitation for untrained rescuers. Some organizations prefer the rescuer to stay in control.
- Self-testing and readiness indicator
- Choose a unit with automatic daily or weekly self-tests and a visible ready status. Most AED failures come from neglected maintenance, so the unit must flag problems itself.
- Ingress protection
- For vehicles, boats or outdoor cabinets, look for a stated IP rating against dust and water. Moisture and dust degrade electronics and pad connections in harsh settings.
Brands that matter
- Philips: HeartStart family is a widespread choice for homes, offices and schools.
- ZOLL: Known for CPR feedback. Also owns the Powerheart line from Cardiac Science.
- Stryker: Makes the LIFEPAK line, with connected readiness monitoring on the CR2.
- Defibtech: Lifeline series, a common value-oriented choice for organizations.
- Cardiac Science: Powerheart G5 line, now under ZOLL.
What to avoid
- AEDs without current FDA approval or sold as unsupported gray-market imports
- Refurbished units without new pads, a fresh battery and a valid warranty
- Buying without budgeting for pad and battery replacements on schedule
- Training units, which cannot deliver a shock, mistaken for real AEDs
Questions
Do I need a prescription to buy an AED?
In the US most AEDs technically require a prescription, which sellers usually arrange through a physician. The Philips HeartStart Home version is cleared for over-the-counter sale.
Can an AED shock someone who doesn't need it?
No. The unit analyzes the heart rhythm and only advises or delivers a shock for a shockable rhythm.
