Emergency service is a health unit established in hospitals and other health institutions to serve patients who require emergency medical assistance. Emergency services operate by dividing into various units according to the patient's complaint and the urgency of the health condition. After the increase in the intensity of the emergency services since the 1960s, this unit started to serve by dividing into 3 groups. These groups are classified according to the symptoms of the patient and are classified as follows:
Red area: This group concerns priority emergency patients. The red area unit deals with life-threatening serious injury or serious illness. Patients included in the red area are in the class requiring the most emergency. Medical interventions for people with heart attack symptoms, serious respiratory problems, sharps and puncture injuries and multiple trauma are carried out in the red area unit. In addition, patients brought to the emergency room by ambulance are also included in this group.
Yellow area: An accident, trauma, etc. yellow area unit provides service for medical intervention in case of having diseases that risk permanent damage to his body as a result of this. Patients who are directed to the yellow area can wait for a while before the intervention.
Green area: The green area unit serves in cases of mild injury and illness. The health status of the patients in the green area is less urgent than the patients in the yellow and red areas. For this reason, patients in this group may wait for a long time, especially in crowded hospitals.
After the triage (system for determining the priority of medical intervention in the emergency services) process of the patients, the intervention should be done in the relevant unit as explained above.
