When a person is sick or injured, if the condition is urgent or serious or if you have an emergency at night, you can go to the emergency department. When you arrive at a hospital emergency department, you usually have to get a hospital medical card and then go to the triage desk, where the triage nurse will first briefly inquire about your condition, take basic vital signs such as temperature, respiration, blood pressure, pulse, and finger pulse oxygen, and then register you to the appropriate department according to the type of illness and severity of your condition. Those with minor illnesses line up to be seen in order, such as emergency internal medicine, emergency surgery, emergency pediatrics and other departments. Some hospitals do not have emergency clinics at night for oral cavity, ear, nose and throat, ophthalmology, obstetrics and gynecology, etc. Emergency patients are taken care of by ward doctors, and after registering for emergency triage, they go directly to the inpatient wards. If the condition is more urgent and serious, the nurse at the triage desk will send the patient directly to the resuscitation room for priority treatment, so that he or she can be resuscitated first and then have a visiting card, register and pay the fee.
