Discover why CPR, AED skills and emergency preparedness are essential in international schools.
A medical emergency can happen without warning. Knowing how to perform CPR and use an AED can make the difference between life and death.
Imagine a busy school morning. Students are arriving for lessons, teachers are preparing their classrooms and sports activities are taking place across the campus. Suddenly, an adult collapses. A colleague rushes over, calls their name and tries to wake them, but there is no response. The person is not breathing normally.
What happens next?
Someone needs to recognise that this could be cardiac arrest, call emergency medical services, start CPR and arrange for an Automated External Defibrillator (AED) to be brought to the scene.
Every second matters. Without immediate intervention, the person's chances of survival can decrease rapidly.
This is why CPR AED training is an essential part of emergency preparedness in schools. Teachers, administrative employees, sports coaches and other school personnel may be the first people available to help before professional medical assistance arrives.
Bangkok First Aid recently delivered CPR AED training at Concordian International School in Bangkok, highlighting the importance of developing practical lifesaving skills within an international school community.
Located in the Bangkok metropolitan area, Concordian International School is an International Baccalaureate (IB) World School offering education from Pre-Kindergarten to Grade 12. The school provides a trilingual learning environment in English, Mandarin Chinese and Thai.
Its extensive campus includes swimming pools, football fields, indoor sports facilities, gymnasiums, a large theatre and dedicated student areas. The school also lists four full-time nurses among its campus facilities. These characteristics make emergency preparedness an important consideration across different areas of school life. <Cite refs={["turn818713search2"]}/>
In this article, we explore why CPR and AED training for international schools matters, how cardiac arrest occurs, what rescuers should do during an emergency and how practical training can help create a safer school community.
Why Is CPR AED Training Important in International Schools?
International schools are active environments. Students spend their days attending lessons, participating in sports, enjoying recreational activities and interacting with teachers and classmates.
Medical emergencies can occur in any of these environments.
A student might suddenly collapse during a physical education lesson. A teacher may experience a cardiac emergency during a meeting. A visitor attending a school performance might become unresponsive, or someone may require immediate assistance during a sporting event.
Although cardiac arrest is not the most common medical emergency in schools, it is one of the most time-critical.
When cardiac arrest occurs, the heart suddenly stops pumping blood effectively. Without immediate intervention, the brain and other vital organs are deprived of oxygen.
Early CPR and rapid defibrillation are two of the most important interventions in the response to cardiac arrest.
The American Heart Association's 2025 Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care emphasise early recognition, activation of emergency assistance, high-quality CPR and prompt AED use. <Cite refs={["turn818713search0","turn818713search6"]}/>
For an international school, emergency preparedness should involve more than the medical team.
Teachers, teaching assistants, administrative employees, sports coaches, security personnel and other staff may be closest to the person experiencing an emergency.
Providing these employees with appropriate CPR AED training in Bangkok helps extend emergency-response knowledge throughout the school community.
Participants learn how to:
- Recognise the signs of cardiac arrest.
- Check responsiveness and breathing.
- Activate emergency medical services.
- Perform effective chest compressions.
- Understand the importance of rescue breaths.
- Operate an Automated External Defibrillator.
- Coordinate with other responders.
- Continue providing assistance until professional medical personnel arrive.
The objective is not to turn every employee into a medical professional. It is to ensure that people know how to recognise an emergency and provide appropriate assistance while waiting for professional help.
Understanding Cardiac Arrest: What Happens Inside the Body?
To understand why CPR AED training is important, it helps to understand what happens during cardiac arrest.
The heart is a muscular organ responsible for circulating blood throughout the body. Blood carries oxygen and nutrients to the brain, lungs and other vital organs.
The heart has an electrical system that controls its rhythm and coordinates its contractions.
During cardiac arrest, this electrical activity becomes severely abnormal or the heart stops producing an effective pumping action.
Blood circulation is interrupted, and the body's organs rapidly begin to suffer from a lack of oxygen.
What are the warning signs?
A person experiencing cardiac arrest will generally:
- Suddenly collapse.
- Become unresponsive.
- Stop breathing normally or only make occasional gasping movements.
One important point is that gasping is not normal breathing.
A person may make occasional unusual breathing movements during cardiac arrest. These are called agonal respirations and should not delay the initiation of CPR.
If someone is unresponsive and not breathing normally, cardiac arrest should be suspected.
Responders should not waste valuable time trying to establish a diagnosis.
Why is immediate intervention necessary?
The brain depends on a continuous supply of oxygen-rich blood.
When circulation stops, oxygen delivery to the brain is interrupted. Brain injury can develop rapidly, and the probability of survival decreases as the time without effective circulation increases.
CPR helps maintain some blood flow while an AED can identify certain abnormal heart rhythms that may respond to an electric shock.
This is why the first people present during an emergency play such an important role.
Recognising cardiac arrest, calling for help and starting CPR immediately can help preserve the person's chances of survival.
CPR: The Most Important First Response
Cardiopulmonary resuscitation (CPR) is an emergency procedure used when someone experiences cardiac arrest.
It combines chest compressions and, when appropriate, rescue breaths to help maintain blood circulation and oxygen delivery.
CPR does not normally restart the heart by itself. However, it can maintain some blood flow to the brain and other vital organs until further treatment becomes available.
How to perform adult CPR
The basic response to a suspected adult cardiac arrest involves several important steps.
1. Check the scene for safety
Before approaching the person, ensure that there are no immediate dangers to yourself, the casualty or other people.
2. Check responsiveness
Tap the person's shoulders and shout to see whether they respond.
If there is no response, treat the situation as an emergency.
3. Check breathing
Look for normal breathing.
If the person is unresponsive and not breathing normally or is only gasping, suspect cardiac arrest.
4. Activate emergency medical services
Call Thailand's emergency medical number, 1669, and request an ambulance.
Ask another person to retrieve the nearest AED.
If you are alone, use your mobile phone to activate emergency assistance and follow the dispatcher's instructions.
5. Start chest compressions
Place the heel of one hand in the centre of the chest, on the lower half of the sternum.
Place your other hand on top, keeping your arms straight and shoulders positioned above your hands.
Push firmly and quickly.
6. Maintain high-quality CPR
For adults, the recommended compression rate is 100–120 compressions per minute, with a depth of approximately 5–6 cm.
Allow the chest to recoil completely between compressions and minimise interruptions.
For trained rescuers providing conventional CPR, the usual ratio is 30 compressions followed by two rescue breaths.
7. Continue CPR
Continue until an AED is ready to analyse the heart rhythm, professional responders take over, the person shows signs of life or you are physically unable to continue.
Why is compression quality important?
Effective chest compressions help generate blood flow during cardiac arrest.
If compressions are too shallow, too slow or interrupted too frequently, circulation may become less effective.
Allowing complete chest recoil between compressions is also important because it helps the heart refill with blood.
Practical CPR training gives participants an opportunity to develop these techniques using training manikins and instructor feedback.
The objective is not simply to perform chest compressions, but to maintain effective and consistent CPR throughout the emergency response.
Child and Infant CPR: Understanding the Differences
An international school such as Concordian welcomes children across a wide age range, from early childhood through to secondary education.
This means that emergency responders may need to assist infants, young children, teenagers or adults.
Although the basic principles of resuscitation are similar, paediatric CPR differs from adult CPR.
Children and infants have different anatomical and physiological characteristics. The compression technique, hand placement and ventilation approach must therefore be appropriate for their age and size.
CPR for children
For children, compressions should be performed using one or two hands depending on the child's size and the rescuer's ability to achieve the recommended depth.
The compression depth should be approximately one-third of the chest's front-to-back diameter.
CPR for infants
For infants under one year of age, the compression technique is different.
The rescuer uses an age-appropriate technique, such as the heel of one hand or the two-thumb encircling-hands technique, depending on the applicable protocol and number of rescuers.
The compression depth should also be approximately one-third of the chest's front-to-back diameter.
Why are rescue breaths important?
In paediatric cardiac arrest, respiratory problems are frequently involved.
For this reason, rescue breaths are particularly important when providing CPR to children and infants.
Training should explain the appropriate compression-to-ventilation ratios and techniques for different age groups.
Knowing the differences between adult, child and infant CPR is particularly valuable for teachers and employees working in schools.
AED: Understanding the Role of an Automated External Defibrillator
An Automated External Defibrillator (AED) is a portable electronic device designed to analyse the heart's electrical rhythm and deliver an electric shock when indicated.
AEDs are important because some types of cardiac arrest involve electrical activity that can be treated with defibrillation.
The two principal shockable rhythms are:
- Ventricular fibrillation (VF): The ventricles produce chaotic electrical activity and cannot pump blood effectively.
- Pulseless ventricular tachycardia (pVT): The ventricles beat extremely rapidly, preventing effective circulation.
An AED analyses the heart rhythm and determines whether a shock is advised.
Not all cardiac arrest rhythms are shockable. Asystole and pulseless electrical activity, for example, require CPR and advanced medical treatment rather than defibrillation.
How to use an AED
AEDs are designed to guide rescuers through the procedure using voice and visual instructions.
The basic steps are:
1. Switch on the device.
Open the AED and press the power button if necessary.
2. Expose the chest.
The chest must be accessible so that the electrode pads can be attached correctly.
3. Apply the electrode pads.
Follow the diagrams on the pads. For typical adult placement, one pad is positioned on the upper right chest and the other on the lower left side.
4. Allow the AED to analyse the rhythm.
Ensure that nobody touches the person during rhythm analysis.
5. Deliver a shock if advised.
If the AED identifies a shockable rhythm, it will instruct the rescuer to deliver a shock.
Make sure everyone is clear before pressing the shock button, if required.
6. Resume CPR immediately.
Follow the AED's instructions and continue CPR.
The device will periodically analyse the heart rhythm again and provide further instructions.
Why should AEDs be accessible in schools?
A school campus may contain classrooms, sports fields, swimming pools, gymnasiums and large gathering areas.
If cardiac arrest occurs, the time required to retrieve an AED can influence how quickly defibrillation is delivered.
Schools should therefore consider the positioning and accessibility of AEDs across their facilities.
Staff should know where devices are located, how to access them and how to communicate their location during an emergency.
AEDs must also be maintained according to the manufacturer's instructions. This includes checking operational status, batteries and electrode-pad expiry dates.
An AED does not replace CPR. Both are essential components of the response to cardiac arrest.
Why Is CPR AED Training Particularly Relevant to Concordian International School?
Concordian International School has an extensive campus with different environments in which medical emergencies could occur.
Its combination of academic facilities, sports infrastructure, swimming pools and large event spaces makes emergency preparedness relevant to many members of the school community.
1. Sports and Physical Education
Concordian provides extensive sports facilities, including three air-conditioned gymnasiums, indoor basketball and badminton courts, football facilities, outdoor playing fields and a 100-metre running track. <Cite refs={["turn818713search2"]}/>
Physical education and sports are important parts of student development.
However, intense physical activity can sometimes reveal an underlying medical condition.
Potential emergencies include:
- Sudden collapse.
- Severe breathing difficulties.
- Heat-related illness.
- Serious injuries.
- Cardiac arrest.
Sports coaches and teachers should understand how to recognise serious warning signs and activate the appropriate emergency response.
CPR AED training helps staff understand what to do if someone suddenly collapses during physical activity.
2. Swimming Pools and Aquatic Activities
Concordian's campus includes a covered 50-metre competition pool, a 25-metre swimming pool and a separate wading pool for younger students. <Cite refs={["turn818713search2"]}/>
Swimming is an excellent physical activity, but emergencies in and around water require specific safety procedures.
Drowning can cause a lack of oxygen and may lead to cardiac arrest.
The first priority is to raise the alarm and ensure that any rescue is performed safely.
Once a person has been safely removed from the water, check responsiveness and breathing and activate emergency medical services.
If the person is unresponsive and not breathing normally, CPR must begin promptly.
Rescue breaths are particularly important in drowning-related cardiac arrest because the initial problem is often a lack of oxygen.
An AED should be used as soon as it becomes available, following its instructions and ensuring that the person's chest is sufficiently dry for pad placement.
Water safety requires prevention, appropriate supervision, safe rescue arrangements and an effective emergency response.
3. School Events and Large Gatherings
Concordian also has a large theatre and shared facilities used for performances, assemblies, seminars and school events.
During these activities, students, parents, teachers and visitors may be present in different areas of the campus.
Emergency preparedness should include clear procedures for contacting medical assistance and guiding emergency responders to the correct location.
Staff should understand how to communicate the location of an emergency and how to obtain assistance without creating unnecessary confusion.
4. A Multilingual School Community
Concordian provides a trilingual educational environment in English, Mandarin Chinese and Thai.
This diversity is one of the school's distinctive characteristics.
During an emergency, however, clear communication is essential.
Staff should understand how to give simple instructions, communicate the casualty's location and coordinate with colleagues.
Emergency procedures should use consistent terminology that can be understood by the people responsible for implementing them.
Effective emergency response depends not only on technical skills but also on communication and teamwork.
Four Full-Time Nurses: Why Everyone Should Know CPR
Concordian's official facilities information identifies four full-time nurses on campus. <Cite refs={["turn818713search2"]}/>
Having qualified nursing personnel available is an important resource for student health and wellbeing.
However, nurses cannot necessarily be present at every location when an emergency occurs.
A cardiac arrest may happen during a sports activity, an outdoor lesson or a school event in another part of the campus.
This is why emergency preparedness should involve more than the medical team alone.
Teachers, administrative employees, sports coaches, security personnel and other staff may be the people closest to the casualty when an incident occurs.
CPR AED training helps extend emergency-response knowledge throughout the school community.
It also helps employees understand how to contact the nursing team, activate emergency procedures and provide immediate assistance while waiting for additional support.
The objective is to create a coordinated response in which everyone understands their responsibilities.
Practical CPR AED Training: Turning Knowledge into Skills
Reading about CPR and AEDs is useful, but understanding the theory is not the same as being able to perform the procedures.
Practical training allows participants to practise essential techniques in a controlled environment.
During CPR AED training, participants can develop familiarity with the equipment and understand how different steps fit together.
Depending on the course, practical exercises may include:
CPR Manikin Practice
Participants practise chest compressions on training manikins.
They learn correct hand placement, body positioning, compression depth and compression rate.
This helps develop the physical skills required to perform CPR.
AED Training
Participants practise switching on an AED trainer, applying electrode pads and following the device's instructions.
They learn why nobody should touch the casualty during rhythm analysis or shock delivery.
Emergency Response Scenarios
Scenario-based exercises allow participants to apply their knowledge in a simulated emergency.
For example, a scenario may involve a person collapsing unexpectedly and requiring CPR and AED assistance.
Participants must recognise the emergency, activate assistance and perform the appropriate procedures.
These exercises also encourage participants to think about teamwork and communication.
Building Confidence Through Repetition
Confidence develops through understanding and practice.
Repeating the procedures helps participants become more familiar with the steps involved and recognise what needs to happen during an emergency.
The purpose of practical training is to help participants move from knowing what CPR is to understanding how to perform it correctly.
The Importance of Teamwork During a Cardiac Emergency
A cardiac arrest emergency can be difficult for one person to manage alone.
When several trained people are available, they can divide responsibilities and work together.
Consider a hypothetical situation in which a visitor collapses during a school event.
One employee checks the person's responsiveness and breathing and recognises that cardiac arrest is suspected.
A second person contacts emergency services, while another retrieves the AED.
The first responder begins CPR.
When the AED arrives, another trained person prepares the device and follows its instructions.
This coordinated response helps ensure that several important actions take place simultaneously.
Clear responsibilities make a difference
A school emergency action plan should establish responsibilities such as:
- Identifying the emergency and initiating the response.
- Contacting emergency medical services.
- Retrieving the AED.
- Providing CPR.
- Guiding emergency responders to the casualty.
- Managing other students and bystanders.
The exact responsibilities depend on the school's organisation and the number of people available.
Practical training helps participants understand why communication, coordination and clear instructions are essential.
Teamwork can reduce delays and improve the organisation of an emergency response.
Building a Stronger Emergency Preparedness Programme
CPR AED training is an important step towards creating a safer school environment, but training should be supported by appropriate equipment and procedures.
Schools can strengthen their emergency preparedness through several practical measures.
Regular AED Checks
AEDs should be checked according to the manufacturer's instructions.
This includes verifying operational status, battery condition and electrode-pad expiry dates.
Staff should also know where the devices are located and how to access them.
Clear Emergency Procedures
The school should have a clear procedure explaining how to respond when someone collapses.
Staff should understand how to contact emergency services, retrieve the AED and guide emergency responders to the casualty.
Accessible First Aid Equipment
First aid kits and emergency equipment should be available in appropriate locations.
Their contents should be checked regularly to ensure that necessary supplies are available.
Regular Training and Refresher Sessions
CPR skills should be practised regularly.
Refresher training helps participants maintain familiarity with the procedures and review changes in recognised guidelines.
New employees should also receive appropriate emergency-response information.
Review Emergency Exercises
Schools can periodically review their emergency procedures and conduct exercises to identify possible improvements.
These exercises can help identify practical issues, such as difficulties locating equipment, unclear responsibilities or delays in communicating the casualty's location.
A well-prepared school combines trained personnel, appropriate equipment and clear emergency procedures.
Participant Voices: Why Learning CPR Matters
Learning CPR and AED skills can change the way people think about medical emergencies.
Many people know that CPR is important, but they may not realise how quickly they need to act when someone becomes unresponsive and stops breathing normally.
Michael
“Before the training, I knew CPR was important, but I had never really understood what I should do first. Practising the different steps helped me understand how to react and why it is important not to waste time during an emergency.”
Sarah
“The AED was one of the most interesting parts of the training. I did not realise how easy the device is to follow. It gives instructions and helps the rescuer understand what to do.”
Nattapol
"Everyone practices and everyone learns. An emergency can happen at work, at school or even at home. Knowing the basic steps could help save someone's life.”
Emily
“The practical exercises helped me understand the importance of teamwork. During a real emergency, several people can help by calling for assistance, retrieving the AED and performing CPR.”
Daniel
“What I found most important was learning how quickly a situation can become serious. I now understand why recognising cardiac arrest and starting CPR immediately are so important.”
