This FAQ covers everything you need to know about buying a defibrillator (AED) in 2026, from what it is and how it works to legal requirements, costs, and maintenance. Whether you're a beginner or a professional, you'll find clear, concise answers to the most common questions.

What is a defibrillator and how does it work?

A defibrillator is a medical device that delivers an electric shock to the heart to restore a normal rhythm during sudden cardiac arrest. It works by analyzing the heart's rhythm and, if a shockable rhythm like ventricular fibrillation is detected, it delivers a controlled electric current through the chest to depolarize the heart muscle, allowing the natural pacemaker to resume normal beating.

Modern defibrillators, especially Automated External Defibrillators (AEDs), are designed for use by laypeople with minimal training. They provide voice prompts and visual instructions, making them safe and effective in emergencies.

Why should I buy a defibrillator for my home or business?

Having a defibrillator on-site can significantly increase the chance of survival after sudden cardiac arrest, which is a leading cause of death worldwide. For every minute that passes without defibrillation, the survival rate drops by 7-10%.

  • Time is critical: Emergency services may take several minutes to arrive; an AED can be used immediately.
  • Easy to use: AEDs are designed for anyone, even without medical training.
  • Legal compliance: In some countries, AEDs are mandatory in certain public places like gyms, schools, and large workplaces.
  • Peace of mind: Knowing you can act in an emergency is invaluable.

For businesses, it can also enhance your corporate social responsibility profile and may reduce liability in some jurisdictions.

How do I choose the best defibrillator for my needs?

Choosing the best defibrillator depends on your specific context: home, workplace, school, or public access. Key factors include the device's ease of use, durability, battery life, electrode pad lifespan, and the availability of training or support.

  • For home: Compact, simple models with long battery life, like the Philips HeartStart Home AED.
  • For business/public: Devices with higher IP ratings for dust/water resistance, and features like CPR feedback, such as the Zoll AED Plus or Physio-Control LIFEPAK CR2.
  • Budget: Prices range from around €900 to €2,500. Consider the cost of replacement pads and batteries over time.

Always check that the device meets local regulatory standards (e.g., CE marking in Europe, FDA approval in the US).

What is the difference between an AED and a professional defibrillator?

The main difference is that an AED is automated and designed for use by laypeople, while a professional defibrillator is manual and used by healthcare providers. AEDs analyze the heart rhythm and decide whether a shock is needed, then guide the user through the process. Professional defibrillators allow the operator to manually control the shock settings and read ECG waveforms.

For most non-medical buyers, an AED is the appropriate choice because it is safe, accessible, and requires minimal training. Professional devices are typically not sold to the general public and require special certification to use.

Where can I buy a defibrillator in Germany?

You can buy defibrillators from specialized medical supply stores, online retailers, and directly from manufacturers. In Germany, common options include Sanitätshäuser (medical supply stores), large online marketplaces like Amazon, and dedicated AED shops such as defishop.de or AED-Superstore.de.

When purchasing, ensure you're buying from a reputable source that offers genuine products, warranty, and after-sales support. It's also wise to check if the price includes accessories like wall mounts or carrying cases.

Do I need a prescription or training to buy a defibrillator?

No, you do not need a prescription or special training to buy a defibrillator in most countries, including Germany and the US. They are classified as medical devices, but they are available for purchase by the general public and businesses.

However, it is strongly recommended to undergo basic first aid and CPR training to familiarize yourself with the device and emergency procedures. Many sellers offer training courses or include instructional materials with the purchase.

What is the legal requirement for defibrillators in public places in 2026?

Legal requirements for defibrillators are expanding. In Germany, for example, the
