When a Medical Emergency Happens at School, Every Second Matters
Imagine a pupil suddenly collapsing during a sports activity. A teacher approaches and discovers that the child is unresponsive and not breathing normally. One member of staff immediately activates the school's emergency response procedure and calls for medical assistance. Another retrieves the nearest automated external defibrillator (AED), while a colleague prepares to begin cardiopulmonary resuscitation (CPR).
Within moments, several important decisions must be made. Can the staff recognise cardiac arrest? Does someone know how to perform effective CPR? Can the team coordinate its actions while ensuring that emergency services can reach the casualty without delay?
This is a hypothetical scenario, not an account of an incident at Brighton College Bangkok. It illustrates how quickly an ordinary school activity can become a medical emergency and why staff preparedness is essential. In an educational environment, an emergency may occur in a classroom, on a sports field, beside a swimming pool, during a school performance or at an extracurricular activity. The people closest to the casualty are often the first available responders.
In cases of sudden cardiac arrest, the actions taken during the first few minutes can have a significant influence on survival. The American Heart Association (AHA) 2025 Guidelines for Cardiopulmonary Resuscitation and Emergency Cardiovascular Care emphasise early recognition, activation of the emergency response system, high-quality CPR and rapid defibrillation when indicated.[1] These interventions form essential links in the chain of survival.
Recognising the importance of these skills, Bangkok First Aid delivered First Aid, CPR & AED training at Brighton College Bangkok, supporting the development of emergency-response knowledge within the school environment. Having an emergency plan, medical equipment and access to professional assistance is important, but staff must also know how to respond when an emergency actually occurs.
Why First Aid Training Is Essential in International Schools
An international school is a complex environment involving pupils of different ages, teaching staff, administrative employees, coaches, support teams and visitors. Throughout the school day, people move between classrooms, sports facilities, dining areas, laboratories, swimming pools and performance spaces.
Each environment presents different potential medical risks. A pupil may experience an asthma attack during a lesson, sustain an injury during physical education, develop an allergic reaction after eating or suffer a medical emergency during an extracurricular activity.
School nurses and healthcare professionals play an essential role in student welfare. However, they cannot necessarily be present at every location at every moment. Teachers, coaches and other employees may therefore be the first people available to recognise an emergency and initiate the response.
First Aid, CPR and AED training gives staff the knowledge and practical skills to provide appropriate assistance while professional medical support is being arranged. It also helps establish a consistent approach to emergency response, reducing uncertainty and improving communication.
A prepared school community should be able to:
- Recognise life-threatening medical emergencies.
- Assess the scene and identify immediate dangers.
- Check responsiveness and normal breathing.
- Activate the school's emergency response procedure.
- Contact emergency medical services.
- Begin CPR when cardiac arrest is suspected.
- Retrieve and operate an AED safely.
- Provide appropriate first aid for common injuries and medical conditions.
- Communicate clearly with colleagues, school nurses and emergency responders.
- Monitor a casualty until further medical assistance arrives.
The objective is not to turn teachers into healthcare professionals. It is to ensure that the people present can recognise an emergency and take appropriate action rather than losing valuable time.
Understanding Emergency Risks Across Brighton College Bangkok's School Environment
A school is not a single working environment. Its facilities support a wide range of educational, sporting and extracurricular activities, each with different emergency-response considerations.
Brighton College Bangkok's official information describes facilities at its Krungthep Kreetha campus that include swimming pools, playing fields, an athletics track, a sports complex and performance facilities.[6] These examples illustrate why emergency preparedness in an educational environment must extend beyond classroom incidents.
The facilities discussed below relate specifically to the Krungthep Kreetha campus. Brighton College Bangkok also has a Vibhavadi campus, and this article does not assume which campus hosted the training.
Sports Fields and Athletics Facilities
Physical education, athletics and competitive sports involve exertion, movement and sometimes physical contact. Potential emergencies include:
- Sprains, strains and fractures.
- Bleeding and open wounds.
- Head injuries and suspected concussion.
- Heat exhaustion and heat stroke.
- Asthma attacks and breathing difficulties.
- Sudden cardiac arrest.
- Collapse during or immediately after physical activity.
Staff should understand how to assess an injured pupil, recognise warning signs and determine when emergency medical assistance is necessary.
A head injury, for example, should never be dismissed simply because the pupil initially appears well. Symptoms of concussion may include headache, dizziness, confusion, nausea, memory difficulties and sensitivity to light or noise. Suspected serious head or spinal injuries require appropriate medical assessment and careful handling.
Swimming Pools and Water-Based Activities
Swimming pools require particular attention because drowning can cause respiratory impairment and cardiac arrest. A casualty rescued from the water may be unresponsive and not breathing normally, requiring immediate resuscitation.
Drowning-related cardiac arrest is primarily associated with a lack of oxygen. Consequently, CPR with rescue breaths is particularly important when the rescuer is trained and able to provide them. The AHA's recommendations for resuscitation in special circumstances address the specific management of drowning emergencies.[4]
A coordinated response should include:
- Ensuring the safety of rescuers and removing the casualty from the water safely.
- Activating emergency medical services.
- Assessing responsiveness and breathing.
- Beginning CPR, including rescue breaths where possible.
- Obtaining and applying an AED as soon as available.
- Following the AED's instructions and ensuring the chest is sufficiently dry for electrode-pad placement.
Staff should not waste time attempting to drain water from the lungs. Abdominal thrusts and other attempts to remove water are not recommended. Resuscitation should begin promptly.
Classrooms, Laboratories and Dining Areas
Medical emergencies are not limited to sports activities. In classrooms, laboratories and dining areas, staff may encounter choking, allergic reactions, asthma attacks, seizures, fainting, burns, cuts and accidental exposure to chemicals.
Choking is particularly relevant in environments where pupils eat together. A severe airway obstruction can rapidly become life-threatening if the person cannot breathe or cough effectively.
Anaphylaxis is another serious concern in schools, especially where pupils have known food or medication allergies. Staff should understand the signs of a severe allergic reaction and know how to follow the pupil's emergency plan.
Theatres, Events and School Gatherings
Assemblies, performances, concerts, competitions and other school events may bring together large numbers of pupils, staff, parents and visitors.
An emergency in a crowded environment can create additional challenges. Access to the casualty may be difficult, people may gather around the incident, and emergency responders may need assistance finding the correct entrance or location.
A school emergency plan should therefore identify who is responsible for contacting emergency services, retrieving medical equipment, guiding responders and managing the surrounding area.
Recognising Cardiac Arrest and Starting Effective CPR
Sudden cardiac arrest occurs when the heart abruptly stops pumping blood effectively. The casualty becomes unresponsive and is not breathing normally. Without immediate intervention, the brain and other vital organs are deprived of oxygen.
Cardiac arrest can occur in adults and children. Although the underlying causes may differ, rapid recognition and resuscitation are essential.
A person who is unresponsive and not breathing normally should be treated as being in cardiac arrest. Occasional gasping or abnormal breathing should not be mistaken for normal breathing.[1]
High-Quality CPR: The Fundamentals
Cardiopulmonary resuscitation (CPR) combines chest compressions and, where appropriate, rescue breaths. Chest compressions help circulate blood to the brain and heart while the casualty awaits further treatment.
For adult CPR, the AHA recommends:
- A compression rate of 100–120 compressions per minute.
- A compression depth of approximately 5–6 cm.
- Hand placement in the centre of the chest, over the lower half of the sternum.
- Full chest recoil after each compression.
- Minimal interruptions.
- A compression-to-ventilation ratio of 30:2 when providing conventional CPR.[1]
The quality of compressions matters. Compressions that are too shallow may not generate sufficient blood circulation, while excessive depth can increase the risk of injury. Leaning on the chest between compressions can also prevent full recoil.
For children and infants, CPR must be adapted to the casualty's age and size. Compression depth, hand position and ventilation techniques differ from adult CPR. The AHA and American Academy of Pediatrics provide specific recommendations for paediatric basic life support.[2]
This distinction is particularly important in schools, where staff may be responsible for pupils ranging from very young children to adolescents.
Why Practical CPR Training Is Essential
Reading about CPR is not the same as performing it. Effective resuscitation requires physical technique, coordination and the ability to act under pressure.
Practical training allows participants to practise:
- Correct hand placement.
- Appropriate compression depth and rate.
- Full chest recoil.
- Minimising interruptions.
- Rescue-breath techniques using appropriate training equipment.
- Changing rescuers when necessary.
- Coordinating CPR with AED use.
Instructors can observe participants, identify technical errors and provide corrective feedback. This helps learners understand not only what to do but also how to perform the skills correctly.
AED Training: Understanding the Importance of Early Defibrillation
An automated external defibrillator (AED) is a portable medical device designed to analyse a person's heart rhythm and determine whether an electrical shock is advised.
Some cardiac arrest rhythms, particularly ventricular fibrillation and pulseless ventricular tachycardia, can be treated with defibrillation. Other rhythms are not shockable and require CPR and further medical management.
An AED analyses the rhythm and determines whether a shock is indicated. The rescuer does not need to diagnose the rhythm manually. The device provides spoken and visual instructions throughout the process.
Early defibrillation is a critical part of the chain of survival when a shockable rhythm is present.[1]
How to Use an AED
The general sequence for using an AED is:
- Ensure that the scene is safe.
- Check responsiveness and normal breathing.
- Activate the emergency response system and request an AED.
- Begin CPR if the casualty is unresponsive and not breathing normally.
- Switch on the AED when it arrives.
- Expose the chest and attach the electrode pads according to the diagrams.
- Ensure nobody touches the casualty while the device analyses the rhythm.
- If a shock is advised, make sure everyone is clear before delivering it.
- Resume CPR immediately after the shock, following the AED's instructions.
- Continue until the casualty shows signs of life, professional responders take over or you are unable to continue.
AEDs are designed to guide rescuers through the process. However, practical training improves confidence, reduces hesitation and helps staff coordinate CPR and defibrillation.
AED Accessibility in Schools
Having an AED on school premises is only one part of an effective defibrillation programme. Its location must be known, access must be maintained and the equipment must be checked in accordance with the manufacturer's instructions.
A school AED management plan should consider:
- Clearly identifying AED locations.
- Ensuring staff know how to access the device.
- Checking battery and electrode-pad expiry dates.
- Maintaining the device according to manufacturer guidance.
- Providing clear instructions for emergency activation.
- Considering access during evenings, weekends and school events.
- Reviewing arrangements for sports facilities and other areas distant from the main building.
An AED that cannot be located or accessed quickly may not be available when it is needed. Staff awareness and practical familiarisation are therefore essential.
First Aid for Common Medical Emergencies in Schools
Cardiac arrest is one of the most time-critical emergencies, but school staff may encounter many other conditions requiring immediate and appropriate action.
Choking: Recognising an Obstructed Airway
Choking occurs when an object obstructs the airway, preventing normal breathing. It can happen during meals, snacks or other activities involving food and small objects.
A person with mild airway obstruction may still be able to cough, speak or breathe. They should be encouraged to cough and observed carefully.
A person with severe airway obstruction may be unable to speak, breathe or cough effectively. This requires immediate intervention.
First aid techniques differ according to the casualty's age. Adult and child choking protocols are not identical to infant choking protocols. Staff should be trained in the correct age-specific sequence, including when to use back blows, abdominal thrusts or chest thrusts and when to begin CPR if the casualty becomes unresponsive.[3]
Anaphylaxis: Recognising a Life-Threatening Allergic Reaction
Anaphylaxis is a severe, potentially life-threatening allergic reaction. It can develop rapidly and affect breathing, circulation and other body systems.
Possible signs include:
- Difficulty breathing or wheezing.
- Swelling of the tongue or throat.
- A hoarse voice or difficulty speaking.
- Dizziness, collapse or signs of shock.
- Widespread skin reactions, including hives or swelling.
A severe allergic reaction requires immediate emergency action. If the casualty has been prescribed an adrenaline auto-injector, it should be administered according to their emergency plan and the device instructions by someone trained or otherwise authorised to assist.
Emergency medical services must be activated. The casualty should be monitored continuously, and CPR should be started if they become unresponsive and are not breathing normally. The AHA and American Red Cross first aid guidelines identify prompt recognition and appropriate management of anaphylaxis as important first aid interventions.[3]
Schools should maintain clear procedures for known allergies, individual emergency plans and access to prescribed medication.
Asthma Attacks
Asthma is a chronic respiratory condition involving inflammation and narrowing of the airways. An asthma attack may cause wheezing, coughing, chest tightness and difficulty breathing.
Staff should recognise signs of a severe attack, including difficulty speaking, worsening breathlessness, exhaustion or reduced responsiveness.
The casualty should be helped to use their prescribed reliever inhaler according to their asthma action plan. Emergency medical assistance should be requested when symptoms are severe, deteriorating or not responding to treatment.
Seizures
A seizure can cause involuntary movements, altered awareness or loss of consciousness. During a seizure, staff should protect the casualty from nearby hazards and avoid restraining their movements.
Important first aid actions include:
- Moving dangerous objects away.
- Protecting the head from injury.
- Timing the seizure.
- Not placing anything in the casualty's mouth.
- Not attempting to hold the casualty down.
- Monitoring breathing once the seizure has stopped.
- Placing the casualty in the recovery position when appropriate and safe to do so.
Emergency medical assistance is particularly important for a first seizure, a seizure lasting five minutes or longer, repeated seizures without recovery, breathing difficulties or significant injury.[3]
Severe Bleeding and Wound Management
Bleeding can range from minor cuts to severe, life-threatening haemorrhage. Staff should understand how to assess the severity of bleeding and apply appropriate direct pressure.
For severe bleeding, immediate firm pressure over the wound is essential. If bleeding is life-threatening and cannot be controlled with direct pressure, a tourniquet may be appropriate for a severe limb injury when available and the responder is trained to use it.
The casualty should be monitored for signs of shock while emergency medical assistance is arranged. The AHA and American Red Cross first aid guidelines provide evidence-based recommendations for managing bleeding and other traumatic injuries.[3]
Burns and Scalds
Burns may result from hot liquids, steam, flames, hot surfaces or chemicals. Their severity depends on the depth, extent and location of the injury.
For thermal burns, the affected area should be cooled with cool running water as soon as possible, ideally for 20 minutes. Ice should not be applied directly to the burn. Jewellery or clothing near the injury should be removed if it is not stuck to the skin.
The burn should be covered with a suitable clean, non-fluffy dressing or material. Serious burns, burns involving the face or airway, extensive burns and chemical or electrical burns require urgent medical assessment.[3]
Heat-Related Emergencies in Thailand
Thailand's climate creates additional considerations for outdoor activities, sports and school events. High temperatures and humidity can increase the risk of heat-related illness, particularly during prolonged physical activity.
Heat exhaustion may involve heavy sweating, weakness, headache, nausea and dizziness. Heat stroke is a medical emergency characterised by severe overheating and possible central nervous system dysfunction, such as confusion, seizures or altered consciousness.
A casualty suspected of having heat stroke requires immediate emergency medical assistance and rapid cooling. Staff should not delay emergency activation while attempting to manage the condition themselves.[3]
Schools should consider hydration, shaded rest areas, activity scheduling and supervision during periods of high heat.
Coordinating an Effective School Emergency Response
An emergency response is rarely the responsibility of one person alone. Several members of staff may need to work together to manage the casualty and the surrounding environment.
A coordinated response may involve:
The first responder: Recognises the emergency, checks the casualty and begins appropriate first aid or CPR.
The emergency caller: Contacts emergency medical services and communicates the school's location, access arrangements and details of the incident.
The equipment responder: Retrieves the AED and first aid equipment.
The access coordinator: Arranges for emergency responders to be met at the entrance and guided to the casualty.
The supporting staff: Help manage other pupils, maintain a safe area and provide additional assistance as required.
These are examples of how responsibilities can be allocated. Each school should develop its own emergency arrangements based on its facilities, staffing structure and procedures.
Communication During an Emergency
Clear communication reduces confusion and helps ensure that appropriate assistance is provided without unnecessary delay.
When contacting emergency services, useful information includes:
- The exact location of the incident.
- The type of emergency.
- The casualty's approximate age.
- Whether the casualty is conscious and breathing normally.
- What first aid or resuscitation has been started.
- Any known hazards or access difficulties.
The school should also have a procedure for informing the appropriate internal personnel and the casualty's parents or guardians, in accordance with its safeguarding and emergency policies.
Practical Training: Turning Knowledge into Action
A written emergency procedure is important, but it cannot replace the ability to perform the necessary actions.
In a stressful situation, people may hesitate because they are uncertain about what to do. Practical training helps turn theoretical knowledge into familiar actions.
During a structured course, participants can practise essential skills using training manikins, AED trainers and other relevant equipment. Instructors can observe performance, provide feedback and reinforce correct techniques.
For example, knowing how to perform CPR is important, but staff must also recognise cardiac arrest, activate the emergency response system and understand how to integrate AED use into resuscitation.
Similarly, knowing how to apply a dressing is useful, but participants must first understand how to assess bleeding and identify signs of a potentially life-threatening injury.
Practical learning also provides an opportunity to discuss common mistakes, such as delaying CPR, failing to recognise abnormal breathing or interrupting compressions unnecessarily. These issues are particularly important because the AHA resuscitation guidelines emphasise early intervention and high-quality CPR.[1]

Building a Culture of Emergency Preparedness
Emergency preparedness should not be treated as a one-time training activity. It is an ongoing responsibility involving people, procedures, equipment and regular review.
Schools can strengthen their emergency readiness through several practical measures.
1. Identify Potential Emergency Risks
Review the school's activities, facilities and population to identify foreseeable medical emergencies. Consider sports, swimming, laboratories, food services, school trips, events and other activities.
2. Establish Clear Emergency Procedures
Ensure staff understand how to activate the school's response system, contact emergency services, retrieve equipment and guide responders to the casualty.
3. Maintain First Aid Equipment
First aid kits and AEDs should be checked regularly. Consumables, batteries and electrode pads must be maintained according to manufacturer instructions and replaced when necessary.
4. Train Staff and Review Competence
Relevant staff should receive appropriate first aid and CPR training. Refresher training and practical skills reviews can help maintain confidence and competence.
5. Practise Emergency Scenarios
Tabletop exercises and practical drills can help staff understand their responsibilities and identify weaknesses in the response plan. Scenarios should be appropriate to the school's environment and should not disrupt or endanger pupils.
6. Review Incidents and Improve Procedures
After an emergency or training exercise, the school should review what worked well and identify opportunities for improvement. Reviews should be constructive and focused on strengthening the system.
Prepare Your School Team to Respond to Emergencies
A medical emergency can happen anywhere: in a classroom, on a sports field, beside a swimming pool or during a school event. The people who are already present may be the first to recognise the problem and take action.
The ability to recognise cardiac arrest, begin CPR, use an AED and provide appropriate first aid can make a critical difference while professional medical assistance is on its way.
First Aid, CPR & AED training is an investment in the safety and preparedness of the entire school community. It gives staff the knowledge and practical skills needed to respond more effectively when an emergency occurs.
Bangkok First Aid provides professional First Aid, CPR & AED training for international schools, educational institutions and organisations throughout Thailand. Courses can be arranged at your premises or at a suitable training venue, depending on the programme and requirements.
