Clinically, the diseases that generally require admission to the emergency room for emergency treatment are relatively critical. If the patient is not given active treatment within a short period of time, it may cause irreversible damage or even result in the patient’s death. Therefore, clinically, for sudden symptoms, especially those related to cardiovascular and cerebrovascular diseases, others such as gastrointestinal bleeding, severe abdominal pain, sudden impairment of consciousness, etc. need to go to the emergency room for treatment. Clinically common cerebrovascular diseases such as sudden dizziness and headache, especially with sensory-motor disorders of the limbs and slurred speech, are considered acute cerebrovascular diseases and require immediate hospital treatment. Cardiovascular diseases, such as sudden panic, sudden difficulty in breathing, and persistent chest pain, are considered to have a high probability of cardiac causes and require immediate emergency treatment in the emergency room to avoid missing the best treatment time. For such as sudden onset of impaired consciousness, fainting, severe abdominal pain, trauma, etc., these require emergency treatment within a short period of time, otherwise there are some diseases that may potentially be harmful and can lead to the death of the patient. It is also a very reasonable process to require doctors to perform first aid within a short time to determine whether the patient needs emergency treatment, and then transfer to a flat clinic if no emergency treatment is needed.
