If a patient presents with cardiopulmonary disease, he or she will need to see the emergency department or circulatory medicine, respiratory medicine, general medicine and general medicine, all of which can be treated. Patients with cardiopulmonary disease who present with acute coronary syndromes, or who present with acute heart failure, respiratory failure, or unstable vital signs due to tension pneumothorax or pulmonary embolism must go to the emergency department of the hospital and be transferred to various departments for further treatment after their vital signs have stabilized. If the patient has previous obvious symptoms of coronary heart disease and belongs to the cardiopulmonary category for follow-up, he/she can go to the cardiovascular department for consultation. For patients with respiratory diseases, such as chronic obstructive pulmonary disease, they can also go to the Department of Respiratory Medicine for consultation. Some hospitals do not have a precise division of medicine, so you can also go to general medicine or general internal medicine for consultation and treatment.
