Ambulance
Overview
An ambulance is a vehicle specially designed to quickly and safely transport patients to medical facilities in emergency situations. It is typically staffed with emergency medical equipment and personnel who provide on-site first aid and treatment during transport, playing a key role in each country's emergency medical system (EMS). The types, equipment, and operational methods of ambulances vary depending on national and regional medical policies, infrastructure, and finances.

History
The origins of the ambulance trace back to the 19th century during the Napoleonic Wars, when horse-drawn carts were used to evacuate wounded soldiers. Modern ambulances emerged in the early 20th century with the development of automotive technology, and they developed substantially after the establishment of the emergency medical system in the United States in the 1960s. In South Korea, the system became more organized after the enactment of the Emergency Medical Service Act in the 1980s.
Types
- Basic Life Support (BLS) Ambulance: Equipped with basic first aid gear and staffed by EMT-Basics, primarily used for transporting patients with mild conditions.
- Advanced Life Support (ALS) Ambulance: Equipped with advanced gear such as defibrillators, ventilators, and medications, and staffed by specialized paramedics (EMT-Paramedic), for responding to severe patients.
- Mobile Intensive Care Unit (MICU) Ambulance: A mobile intensive care unit with critical care equipment, used for inter-hospital transfers.
- Specialized Ambulances: Customized for special environments, such as fire department ambulances, military ambulances, and mountain/water rescue ambulances.
Equipment
Ambulances are required to carry the following essential equipment: oxygen supply devices, automated external defibrillators (AEDs), spinal immobilization boards, stretchers, blood pressure monitors, pulse oximeters, emergency medication kits, airway management devices, and hemorrhage control tools. Recently, telemedicine systems, GPS navigation, and patient monitoring equipment have also been added.
Operational System
Ambulances are dispatched via emergency calls such as 119 (South Korea) or 911 (United States) and arrive at the scene under the direction of a control center. Operating entities vary, including national fire departments, private ambulance companies, and hospital-owned services. In South Korea, the 119 Emergency Medical Service under the National Fire Agency is the main provider, with private transport companies playing a supplementary role. Ambulances are granted traffic law exemptions (e.g., use of sirens, priority passage through signals), but safe driving remains the top priority.
Education and Certification
Ambulance personnel must obtain nationally recognized certifications (in South Korea: Level 1 Emergency Medical Technician, Level 2 Emergency Medical Technician) and undergo regular retraining and practical exercises. In the United States, there is a tiered certification system including EMT-Basic, EMT-Intermediate, and Paramedic.
Legal and Ethical Issues
- Refusal of Transport: Refusing to transport an emergency patient may result in legal liability.
- Privacy Protection: Patient information must be protected in accordance with medical laws.
- Overtreatment: Controversy over the unnecessary use of advanced equipment or excessive procedures.
- Traffic Accident Risk: The risk of accidents during emergency dispatches is high, making driver training crucial.
Latest Trends
As of 2024-2025, major trends in the ambulance field include:
- Introduction of Electric Ambulances: Due to stricter environmental regulations, electric ambulances are being piloted (e.g., in some U.S. states and Europe). Battery range and charging infrastructure remain challenges.
- Integration of Telemedicine: Real-time remote consultation systems using 5G networks are being installed in ambulances, allowing doctors to monitor patients and provide treatment instructions during transport.
- AI-Based Dispatch: Artificial intelligence analyzes call content to recommend optimal ambulance deployment and routes, reducing response times.
- Drone Ambulances: Experiments are underway to rapidly deliver AEDs or emergency medications via drones (e.g., in Sweden and Japan).
- Post-COVID-19 Changes: Dedicated ambulances for infectious patients and enhanced quarantine equipment, along with expanded use of negative-pressure ambulances.
- Data-Driven Quality Management: Analyzing ambulance dispatch records and patient outcome data to improve service quality.
