Bronchiectasis haemoptysis has a high risk of death by asphyxia, so active intervention and treatment are necessary. Patients with a small amount of hemoptysis can be treated with oral Yunnan Baiyao, while patients with a moderate amount of hemoptysis can be treated with intravenous posterior pituitary hormone, phentolamine, and hemostatic aromatic acid. Large hemoptysis is defined as hemoptysis of 100 ml at a time and 500 ml or more a day. Large hemoptysis often cannot be stopped with medications.
