Bronchiectasis is classified as an infectious disease of the respiratory internal medicine, mainly caused by the invasion of various pyogenic bacteria into the respiratory tract, which usually leads to inflammation and fibrotic changes in the bronchi and surrounding lung tissue. Therefore, patients with bronchiectasis often exhibit clinical symptoms such as cough, expectoration, difficulty breathing, chest tightness, and chest pain. It is crucial to provide timely treatments for such patients, including anti-infection measures, cough relief, expectoration, and hemostasis. If bronchiectasis is not effectively treated, it may lead to complications such as hypoxemia and severe bleeding. It is known that bronchiectasis does not lead to cancer due to local inflammation.
