The system of emergency medical technician was newly established in 1995 because of the recognition that, after going through a large scale of disaster, an emergency medical system should be set up in preparation for it. An emergency medical technician's work range, qualification standards, certification tests and other matters are regulated by the law of emergency medical services and its subordinate regulations. When an emergency occurs, an emergency medical technician plays important rolels in an emergency medical system by checking an emergency patient at the field, taking necessary measures and handing over the patient to a medical doctor. An emergency medical technician playing these roles is defined as an emergency medical provider along with healthcare workers by the law of emergency medical services. In general, an emergency medical system is divided into a pre-hospital stage and an in-hospital stage. First, an emergency medical technician at the pre-hospital stage mainly consults, rescues, transfers, gives first aid to and treats an emergency patient. Next, the main duties of an emergency medical technician at the stage of in-hospital are first aid, hospitalization and treatment at an emergency room of an emergency medical organization. However, an emergency medical technician cannot give emergency medical treatment by self that one can do without a doctor's specified directions, that is, medical guidance, except for minor first aids and in the cases where one cannot get a doctor's medical directions because of a problem in communication at an urgent situation. In this way, to the exclusion of some exceptional cases, the given emergency medical treatment corresponds to a medical treatment without a licence according to Article 27 of the medical law, and the emergency medical technician can get punished. Recently, with regard to this, patients' families have charged and filed civil complaints seceral times. An emergency medical technician plays an important role in an emergency, and is the one who is essential in the current emergency medical care. In this situation, it needs to be examined again whether the limits of an emergency medical technician's work are proper or not. This is after all a matter of reflecting the characteristics of emergency medical services and accordingly checking the appropriateness of the range of an emergency medical technician's work. An emergency medical technician is the only professional manpower who can help emergency patients in an emergency, and restrictions on their work do not correspond to the legislation purpose of the the law of emergency medical services. Therefore, as a measure to solve this, there is the measure to reinforce a doctor's medical direction and another measure to realistically adjust the range of emergency medical treatment of the current law of emergency medical services that an emergency medical technician can perform at an emergency without a doctor's medical direction. Not just one solution is necessary, but all of them are mutually organic and worthy of consideration. The occurrence of an emergency necessarily means the existence of an emergency patient, and the need for systematic and proper level of emergency medical care for him. An emergency medical system has to be set up and run simultaneously through which one can cope with an emergency quickly and appropriately. In particular, an emergency medical technician is a main agent playing an important role in the current emergency medical system, and takes on the role of eleminating danger from a person facing death, but if one has to face sanctions because of this, no one will be able to understand it. Therefore, this problem should be solved without fail, and an emergency medical system must be established where emergency medical technicians can work with an easy mind.
