Definition of Emergency and Emergency Care

Emergency Medical Technicians (EMTs) work where minutes matter. To act safely, an EMT must distinguish an emergency from an ordinary health problem, recognize time-critical threats, give immediate care within scope, and arrange safe transfer to the level of care the patient needs.

• Define emergency, emergency care and emergency medical services (EMS).
• Differentiate an emergency, an urgent problem and a non-urgent problem.
• Explain the goals, principles and continuum of emergency care.
• Apply the concepts to common community, road traffic, obstetric and medical presentations.

An emergency is a sudden or acute condition in which delay in recognition, assessment, treatment or referral may cause death, permanent disability, loss of a limb or organ, serious deterioration, or severe suffering. It may result from injury, acute illness, poisoning, violence, an obstetric complication, a mental-health crisis or an environmental exposure.

• Threat to life: airway obstruction, severe breathing difficulty, shock, cardiac arrest, severe bleeding or unconsciousness.
• Threat to organ or limb: stroke symptoms, acute eye injury, testicular torsion, crush injury, compartment syndrome or a cold pulseless limb.
• Risk of rapid deterioration: anaphylaxis, severe asthma, sepsis, diabetic emergency, poisoning or an ectopic pregnancy.
• Need for time-sensitive treatment: trauma, acute coronary syndrome, seizures, eclampsia, severe malaria, meningitis or severe burns.
• Safety threat: violence, attempted suicide, unsafe scene, hazardous chemical exposure or a patient who may harm self or others.

Important: Classification follows assessment, not appearance. A quiet patient may be critically ill, while a noisy patient may be stable. Always look for red flags and use local triage protocols.

An emergency may involve one patient or a few patients. A disaster or mass-casualty incident occurs when the number or severity of patients exceeds the immediately available resources. Both require organized care, but a disaster also requires scene command, major-incident triage, resource mobilisation and communication across services.

Emergency care is the organised, time-sensitive care given to a person with acute illness or injury from the moment the problem is recognised until the person receives definitive treatment, safe admission, referral, discharge or end-of-life support. It is not only “care in the emergency room.” It includes the community, dispatch, pre-hospital response, transport, emergency unit and early inpatient care.

WHO describes an emergency care system as covering essential functions at the scene of illness or injury, during transport, and through the emergency unit and early inpatient care. In practice, the patient should experience a connected pathway rather than separate, uncoordinated services.

• Preserve life and prevent avoidable death.
• Prevent deterioration, disability and complications.
• Relieve pain and distress while maintaining dignity.
• Identify the sickest patient early through triage and structured assessment.
• Deliver the right intervention at the right time and level of care.
• Ensure safe referral, transport, communication and continuity of care.
• Protect patients, families, staff and the public from avoidable harm.

1. Scene safety first: do not become another casualty. Use PPE and identify traffic, violence, fire, electricity, chemicals, crowds and infection hazards.
2. ABCDE before details: treat immediate threats to Airway, Breathing, Circulation, Disability and Exposure while gathering history.
3. Do the greatest good first: prioritize interventions that correct life threats within your scope.
4. Early request for help: call for additional clinical, rescue, police, fire or transport support before the situation becomes unmanageable.
5. Respect, consent and privacy: explain what you are doing where possible; protect the patient from unnecessary exposure and disclosure.
6. Reassess continuously: vital signs and mental state can change rapidly. Document the trend, not only one reading.
7. Communicate and hand over well: give a clear MIST/SBAR-style handover and record the care given.

• An emergency is defined by the risk from delay, not by the patient’s level of noise or anxiety.
• Emergency care is a continuum: recognition → response → transport → emergency-unit care → definitive care.
• EMTs must combine technical care with safety, communication, documentation, ethics and referral planning.
• Triage decides priority; ABCDE identifies and treats life threats.
• When uncertain, treat the patient as potentially serious until assessment proves otherwise.

1. Define an emergency in your own words.
2. State four features that make a condition time-critical.
3. Differentiate an emergency from a disaster.
4. List the six stages of the emergency-care continuum.
5. A patient with suspected stroke looks comfortable but has sudden facial weakness and speech difficulty. Explain why this is still an emergency.

An Emergency Medical Technician (EMT) is a trained pre-hospital care provider who assesses, treats, monitors and transports people with illness or injury within an authorised scope of practice. The EMT links the community, emergency response and receiving health facility.

• Describe the core role of an EMT.
• Explain clinical, safety, communication and professional responsibilities.
• Apply EMT responsibilities to scene care, transport and handover.

The EMT is not simply a driver or a person who carries patients. The EMT brings organised emergency care to the patient, identifies immediate threats, starts indicated treatment, decides on safe transport and communicates essential information to the receiving team. The exact procedures permitted depend on national policy, service protocols, training level, equipment and medical direction.

Before approaching, the EMT assesses traffic, fire, electricity, violence, unstable structures, hazardous materials, crowds and infection risk. Use personal protective equipment and request police, fire, rescue or additional clinical resources when needed. A rescuer who becomes injured cannot help the patient.

Use a systematic primary assessment such as ABCDE: airway, breathing, circulation, disability and exposure. Treat life-threatening problems first. A focused history, vital signs and secondary assessment follow when the patient is stable enough. Identify patients needing urgent transport and a specific facility.

Responsibilities include protocol-authorised care such as airway positioning, ventilation support, oxygen where indicated, bleeding control, shock management, glucose assessment, seizure protection, splinting, positioning and medicine administration only when trained and permitted. Never perform a procedure merely because it is requested or has been seen elsewhere.

Select safe lifting methods and equipment, protect the patient from falls, use stretcher straps and consider trauma, pregnancy and respiratory needs. During transport, reassess vital signs, continue treatment, record changes and balance speed with road safety.

Clear communication prevents dangerous delay. Report location and resource needs, explain care calmly to patients and relatives, alert a receiving facility for critical patients and give concise handover. ATMIST or SBAR can include the problem, history or mechanism, assessment, vital signs, treatment, response and concerns.

Every case record should include times, findings, vital signs, treatment, response, destination and handover. Before and after each shift, check vehicle safety, oxygen, suction, monitoring equipment, PPE, medicines, consumables, communication devices and stretcher function. Report defects and stock gaps promptly.

1. Receive information and prepare the correct equipment.
2. Approach only when the scene is safe.
3. Identify and treat immediate life threats using ABCDE.
4. Gather focused history and repeat vital signs.
5. Decide destination and request additional help or early facility notification.
6. Move and secure the patient safely.
7. Continue care, reassessment and documentation during transport.
8. Give structured handover and restock or report after the case.

An EMT team reaches a rider after a collision. Traffic is active and a crowd is gathering. The team first establishes a safe working area, uses PPE and requests traffic control. The patient has major leg bleeding and is confused. The EMT controls bleeding, assesses airway and breathing, checks circulation and consciousness, prepares the patient for safe transfer, communicates with the receiving facility and reassesses throughout transport. On arrival, the crew provides a structured handover.

• Work within training, scope of practice and service protocols.
• Respect patient dignity, privacy, culture and confidentiality.
• Seek consent when possible; act in the patient's best interests when emergency incapacity applies under authorised practice.
• Remain calm, honest and respectful; never promise outcomes that cannot be guaranteed.
• Do not abandon a patient after taking responsibility unless care is transferred appropriately.
• Avoid discrimination, unsafe driving and careless social-media use.
• Participate in debriefing, skills updates and quality-improvement review.

The EMT must recognise when a patient needs a higher level of care, more resources or medical consultation. Good practice includes requesting help early, communicating limitations, choosing an appropriate destination and documenting decisions. Working beyond scope or improvising unsafe care can harm the patient and the team.

• An EMT is a pre-hospital clinician, not only a transport worker.
• Scene safety comes before patient contact.
• ABCDE guides management of immediate life threats.
• Care continues during transport and ends after a safe handover.
• Scope, protocol, documentation and confidentiality are professional duties.

1. List six responsibilities of an EMT at an emergency scene.
2. Explain why care in transit is an EMT responsibility.
3. Describe a structured clinical handover.
4. State four professional limits or ethical duties of an EMT.
5. Apply the EMT workflow to a road traffic crash.
