The principles of handling bronchial dilatation hemoptysis mainly include the following: 1. Patients who cough up a lot of blood need strict bed rest and try to lie in bed towards the affected side to avoid blood flowing out and causing blockage on the other side of the lung; 2. Stay calm and avoid emotional excitement, which may cause accelerated blood flow and lead to increased blood pressure, resulting in difficulties in stopping bleeding; 3. Eliminate panic about coughing and coughing up bruised blood to help reduce bronchial blockage; 4. Treat through appropriate use of sedatives, medication to stop bleeding, bronchoscopy, interventional therapy and surgery.
