Frequently asked questions about AEDs



This article covers the most frequently asked questions about AEDs. If you miss a question, please let us know so we can add it and the answer. You can also read our various blogs for more information.


What is an AED?

An AED, short for Automated External Defibrillator, is a device that is essential in restoring the heart rhythm during cardiac arrest. It works by administering an electric shock via the AED. During cardiac arrest, it appears as if the heart has stopped beating, although it usually does not stop completely. Instead, the heart chambers are stimulated rapidly and chaotically, resulting in a failure to contract and an ineffective pumping of blood through the body, known as ventricular fibrillation. An AED provides an effective solution to reset the heart and get it back to a normal rhythm.


How does an AED work?
The operation of an AED in the event of cardiac arrest is as follows:

The AED analyses the heart rhythm to determine whether there is an arrhythmia.

If necessary, the AED will give an electric shock to reset the heart and restore it to a normal rhythm. The AED will guide the rescuer step by step:

  • Attach the two electrodes to the victim's chest.
  • The AED reanalyses the heart rhythm.
  • Based on the analysis, the AED instructs to press the button for a shock or to continue CPR.


Where can I take a course in using an AED?
You will learn to use an AED during a CPR course, given by a qualified instructor.

The CPR course includes:

  • Recognizing Cardiac Arrest and the Correct Action
  • Resuscitation techniques, including chest compressions and mouth-to-mouth resuscitation, and the appropriate rate for these
  • How an AED works, including connection and operation

During the course you will practice with a resuscitation dummy and an AED trainer (this is a training device that simulates the use of a real AED for resuscitation training). After completing the resuscitation course you will receive a certificate of participation.
 

At which locations will an AED be installed?
An AED is usually located in public locations such as shopping malls, health centers, town halls and gyms so that they are easily accessible in an emergency.

As a citizen responder, you can also register with HartslagNu . You will receive a notification in the event of a resuscitation and the exact location of the AED. If the outdoor cabinet is locked with a PIN code lock, HartslagNu will also send you the code. If there is no AED available, it is essential to immediately start resuscitation by giving chest compressions and mouth-to-mouth resuscitation.

What are the costs of an AED device?
The cost of an AED can vary depending on several factors, such as the brand, functionality, and included accessories. In general, AED prices range from €1,000 to €2,000. Although this may seem expensive at first, it is important to emphasize that an AED is a life-saving device that can be invaluable in emergency situations. It is wise to take out a service agreement so that the AED is always ready for use.

What should you pay attention to when purchasing an AED?
Ease of use: An AED should be easy to use, even for people without a medical background.

  • Maintenance and service: check that the chosen brand and model offer good warranty and support for maintenance and any repairs.
  • Suitability for the environment: consider where the AED will be placed. Different requirements may apply for public spaces than for home use. Our customer service can advise on this.
  • Price: Compare different models and consider the price in relation to the features and reliability.
  • Quality mark: ensure that the AED has a CE mark and complies with the European MDR guidelines (Medical Device Regulation), as required on the Dutch market.
     

Why doesn't an AED always give shock advice?
No disturbed heart rhythm: An AED analyses the victim's heart rhythm and only gives a shock advice if an abnormal rhythm, such as ventricular fibrillation or ventricular tachycardia, is detected. If the heart rhythm is normal, the AED will not advise a shock.

  • Cardiac Arrest Without Electrical Activity: If the heart has completely stopped and there is no detectable electrical activity, the AED will not advise a shock because there is no disturbed rhythm to correct.
  • Unconsciousness without cardiac problems: If the victim is unconscious but the heart is functioning normally, the AED will not advise a shock because there is no cardiac arrhythmia that needs to be corrected. In such cases, CPR may be necessary, but not defibrillation.
     

Can an AED be used on children?
Yes, an AED can be used on children, but there are some important considerations:

  • Cardiac arrest in children: In children, cardiac arrest is often caused by respiratory arrest, unlike in adults, where the cause often lies in the heart itself. Despite these differences, an AED should always be obtained in the event of cardiac arrest in a child.
  • AED Suitability: Most standard AEDs are suitable for children over the age of eight. Some AEDs are equipped with special child electrodes that deliver less current during a shock. Other AEDs have a child button or adjustment for children in the device itself. If a specific child AED is not available, a standard adult AED can be used.

However, it is important to always seek medical attention and follow the AED instructions carefully in the event of cardiac arrest in a child.


How often can you use an AED?
After an AED has been used, it can generally be reused, but it is important to check the AED's status and replace any necessary parts. Here are some key points:

  • Electrodes: After use, the electrodes often need to be replaced, as they cannot be reused. Make sure you have spare electrodes available in case they are needed on a subsequent deployment.
  • Battery: Check the battery status of the AED regularly. The battery can become empty over time, even if the AED has not been actively used. Make sure the battery is always sufficiently charged or replace it if necessary.
  • Maintenance: It is important to maintain the AED regularly according to the manufacturer's instructions. This may include checking overall operation and replacing consumable parts.

In short, although an AED is usually reusable after a deployment, it is crucial to check the status of the AED and ensure that all necessary components are functioning properly before using it again.

Do the AED batteries need to be replaced after a resuscitation?
An AED battery may need to be replaced after a resuscitation. This is because the battery may have delivered a significant amount of current during use, which may have reduced its capacity. An AED performs self-tests to check the status of the battery, and if the voltage is too low, it will indicate that the battery needs to be replaced.

It is important to note that the lifespan of an AED battery is affected by several factors, including the type of AED and how long it is on standby. In general, batteries last longer when they are kept on standby for long periods of time. However, it is essential to regularly check the battery status and replace it when necessary to ensure that the AED is always ready for use in an emergency.


What is the lifespan of an AED?

The lifespan of an AED varies, but it is generally recommended to replace the AED after about 10 years. However, it is important to ensure that:

Electrodes and batteries are replaced in time according to the manufacturer's guidelines. These parts have a limited lifespan and must be checked regularly and replaced if necessary.

The AED is maintained after use and periodically to ensure that it is always ready for use in emergency situations. This includes performing self-tests and checking the overall operation of the AED.

The warranty period of an AED is usually around 8 years, but this can vary depending on the make and model of the AED. It is important to check the manufacturer's warranty conditions and ensure that any warranty claims are made within the applicable period. By following these guidelines, the effectiveness and reliability of the AED can be guaranteed throughout its lifespan.

The use of a respirator mask
This is a crucial part of cardiopulmonary resuscitation, a life-saving procedure for people who have suffered a cardiac arrest. During cardiac arrest, there is no breathing and no pulse. The goal of cardiopulmonary resuscitation is to restore both circulation and breathing. A resuscitation mask is a device used to blow air into a person’s lungs, allowing artificial respiration. In our blog, we will discuss the importance and proper use of a resuscitation mask during resuscitation.

What is a respirator mask?
A resuscitation mask, also known as a pocket mask, is a mask that is placed over the victim's mouth and nose during CPR. The mask has a mouthpiece through which the rescuer can blow air into the victim's lungs. The resuscitation mask is specially designed to prevent the transfer of pathogens, such as mucus or blood, during resuscitation. This helps protect both the rescuer and the victim from possible infections during resuscitation.

Why do you use a breathing mask?
A resuscitation mask is used during resuscitation when a person can no longer breathe independently. The main purpose of using a resuscitation mask is hygiene. By performing mouth-to-mouth resuscitation using a resuscitation mask, direct physical contact between the rescuer and the victim is avoided. This minimizes the risk of transmission of pathogens, such as viruses or bacteria, between both parties.

Professional rescuers always use a respirator mask due to the importance of hygiene and the lack of time to find out the health status of the victim during an emergency. Even if the rescuer does not know the victim, the use of a respirator mask can be life-saving without the risk of possible contamination.

How do you use a breathing mask?
Using a resuscitation mask in CPR follows a simple procedure. Here are the steps you need to follow:

  • Place the mask over the person's mouth and nose, with the rounded side over the chin and the pointed side near the nose. Make sure the mask fits snugly so that no air can escape.
  • Perform a chin lift and gently tilt the head back to open the airway.
  • Blow air evenly into the victim's mouth through the mask. The breathing mask is equipped with a one-way valve, which only allows air to flow from your mouth to the victim, not the other way around.
  • Check the victim's chest. It should rise with effective ventilation.
  • Repeat this cycle in combination with chest compressions according to current resuscitation guidelines. In adults, a ratio of 30 chest compressions to 2 breaths is usually used.
  • Throw away the used breathing mask after use. The mask is used from a hygienic point of view, both for you and for the victim. Reusing the mask on another victim increases the risk of contamination.
  • By following these steps, mouth-to-mouth resuscitation can be performed effectively and hygienically using a breathing mask during resuscitation.

Learn to ventilate properly
Taking a resuscitation course is indeed essential to learn how to properly ventilate with a pocket mask. During such a course, you will not only learn the correct techniques for resuscitation, but also how to use a resuscitation mask correctly. Moreover, it offers the opportunity to practice under the supervision of experienced instructors.

It is also a good idea to invite your colleagues, co-owners of an Owners' Association (VvE), or neighbors to participate in the course together. In this way, you increase the resuscitation skills within your immediate environment and you can support each other in case of emergency.
