Proper AED Installation Locations

In the school safety system, installing an AED is not merely about equipping a device but is also a critical emergency medical intervention strategy. An AED (Automated External Defibrillator) is a device capable of analyzing the heart rhythm and delivering an electric shock to terminate dangerous arrhythmias such as ventricular fibrillation, a common cause of sudden cardiac arrest. However, the value of this device depends almost entirely on accessibility during the "golden window."

A scientifically arranged AED system, combined with systematic training, will help schools not only meet safety standards but also proactively protect the lives of students, teachers, and the entire school community.

1. Why is the AED installation location more important than the quantity?

In cardiac arrest emergencies, an AED does not "restart" the heart as many mistakenly believe, but helps stop the electrical disturbance so the heart's natural conduction system can re-establish an effective rhythm. This process is only meaningful when performed as early as possible.

According to medical studies, for every minute that passes without defibrillation, the victim's survival rate decreases by 7-10%. Conversely, if an AED is used within the first 3 minutes, the chance of survival can increase significantly, even reaching up to 70% in some real-world studies.

This establishes an important principle in AED installation: it is not about "how many machines you have," but "how long it takes to get the machine." A device placed in the wrong location, obscured, or difficult to access will lose all its life-saving value in an emergency.

2. Ideal response time: The core criterion when installing an AED

The American Heart Association (AHA) recommends that an AED should be used within 3-5 minutes from when the victim collapses. This is a crucial standard for determining AED installation locations in schools. To evaluate practically, schools can apply the response time measurement method:

Choose a planned AED location.
Move from the furthest point to that location and back.
Calculate the total time to access and bring the device back to the scene.

If the time exceeds 3 minutes, additional AEDs need to be added. This approach helps build an "emergency response map," ensuring every area falls within the safe coverage zone. Note that this time does not include actions like turning on the machine, attaching the electrodes, or delivering the shock—factors that may take longer if the user is untrained.

3. Always ensure the AED is ready for operation

Besides location, the device's operational status is also a core factor. Most modern AEDs have a self-test function and display their status via indicator lights or sounds.

During operation, periodic weekly or monthly checks are required, paying special attention to the battery and electrode pads. When the device issues an error warning (red light, sound), the provider must be contacted immediately for timely handling. An effective AED system lies not only in installing the AED in the right place but also in maintaining a "always ready" status.

4. Principles for choosing AED installation locations in schools

In the practical installation of AEDs, several core principles must be prioritized. The choice of location must be based on movement factors, human behavior, and the risk of incidents occurring.

Central, highly visible areas: First, AEDs should be placed in central areas such as main lobbies, corridors, reception areas, or near the medical room. These are places with high foot traffic and are easy to locate in an emergency.
High-risk areas: Areas such as gymnasiums, sports fields, or physical training zones need to be prioritized. High-intensity activity increases the risk of arrhythmias, so placing AEDs near these locations helps shorten intervention time.
Crowded spaces: Auditoriums, cafeterias, or common areas also need to be equipped with AEDs. The principle here is clear: the more crowded the place, the higher the risk of an incident.

5. Barriers to eliminate when arranging AEDs

A common mistake when installing AEDs is ignoring practical physical movement barriers. In a school environment, elements like stairs, elevators, locked doors, crowded corridors, or one-way paths can significantly slow down response time.

Evaluating AED locations must be done under actual conditions, especially during peak hours. A clear corridor in the evening can become heavily congested during recess, directly affecting device accessibility. Furthermore, factors such as partitions, locked rooms, or multiple separate buildings must also be factored into the AED arrangement strategy.

6. Standards for device accessibility and visibility

An important rule in AED installation is that the device must be "visible before it needs to be found." AEDs should not be placed in closed rooms or restricted areas.

Regarding height, international standards recommend the device location should be within easy reach (about 1.2-1.5m), ensuring that adults, students, and people with disabilities can access it quickly.

Note: The device should be placed in an open location with clear signage, even using 3D signs for easy recognition from a distance in large spaces.

7. How many AEDs are enough for a school?

There is no fixed number for every school, as the need for AED installation depends on the area size, number of students, and campus layout. However, the general rule is that every area in the school must have access to an AED within 3 minutes.

For multi-story schools, arranging at least one AED per floor is a common solution. For large campuses or those with multiple separate buildings, additional AED locations must be calculated to ensure coverage. In some special cases, such as infrequently used or seasonal areas, the number of AEDs can be adjusted flexibly. However, the core principle remains ensuring rapid response capabilities in all situations

8. Wellbeing - The optimal AED installation solution for schools

To deploy AED installation effectively, schools need a partner experienced in consulting, equipment, and training. Wellbeing currently provides a comprehensive solution, helping schools not only own AEDs but also operate the system effectively.

Wellbeing supports practical campus surveys, movement density analysis, and proposes optimal installation locations based on response time standards. This helps ensure each device is placed correctly, maximizing its value in emergencies.
Besides, Wellbeing provides genuine AED models from reputable international brands while also deploying AED usage and first aid training programs for teachers, staff, and students. Combining equipment with training helps build a complete emergency response system in schools.

Installing AEDs in schools is not just an equipment requirement but an important part of the overall safety strategy. Choosing the right location, ensuring response time, and eliminating access barriers will determine the life-saving effectiveness in emergency situations.
