Firstly, sensitive antimicrobial agents should be chosen during the acute phase to control the infection, with the preferred medications being beta-lactam antibiotics. Penicillin-type drugs can be administered intravenously for anti-inflammatory treatment. Additionally, medications that dilute phlegm and relieve bronchial smooth muscle spasms should be selected to ease symptoms such as coughing and expectoration. If there is significant hemoptysis, hemostatic drugs should also be considered. For symptoms of respiratory distress accompanied by hypoxia, clinical treatments primarily include oxygen therapy to alleviate symptoms, focusing on symptomatic treatment.
