1. The location: Where will the AED be placed?

The environment determines the robustness you need.

• Outdoor location: Choose an AED with a high IP rating (dust and water resistance). Near a facade or sports field, an outdoor AED cabinet with heating and ventilation is essential to protect the AED battery from frost.

• Indoor location: In an office or shop, a more compact model is often sufficient. A simple wall bracket or indoor cabinet is usually enough here.

2. Ease of use: Who will operate the AED?

In the 6-minute zone, it is usually bystanders (laypeople) who use the AED.

• Fully automatic: The device delivers the shock itself after a warning. This is often the best choice for neighborhoods and public places, as it lowers the barrier to action and removes doubt.

• Semi-automatic: The rescuer must press the button themselves. This is often chosen by trained rescuers who prefer to maintain control.

3. Resuscitation Coaching (Feedback)

Resuscitation is extremely stressful. Advanced models offer resuscitation feedback. Through sensors in the electrodes, the AED measures whether you are pressing deep and fast enough during chest compressions. The device literally coaches you with instructions like "Press harder" or "Good compressions". This significantly increases the quality of assistance.

4. Maintenance and running costs

Look beyond just the purchase price. A "cheap" AED can turn out to be expensive in the long run due to replacement intervals:

• Pad/battery life: Some models require new parts every 2 years, others only after 5 years.

• Carefree management: With a maintenance contract, we monitor the expiration dates for you, ensuring the device is always ready for use.

5. Special features

• Child mode: For schools or daycare centers, a model with a child button is ideal. You don't need to change separate pediatric electrodes then.

• Multilingualism: At a campsite or international office, an AED that can switch between languages is essential so that everyone understands the instructions.
