After a concussion occurs, the injured should be quickly moved from a dangerous environment to a safe area. The injured person should lie flat and rest quietly without sitting up or standing. The head can be appropriately cooled, and it is important to keep the body warm. For patients who are unconscious, it is necessary to keep the airway clear and closely observe their consciousness and pupils. If there are airway secretions or vomiting, they should be cleaned up promptly. If the patient has already experienced respiratory or circulatory problems, immediate cardiopulmonary resuscitation should be performed. After the aforementioned emergency treatment, the next step is to transport the patient to a nearby well-equipped hospital for further diagnosis and treatment.
