In the presence of diseases of the airways and lungs, a respiratory medicine consultation should be chosen to clarify inflammatory and non-infectious diseases of the airways, such as bronchitis, pneumonia, bronchiectasis, lung abscesses, and idiopathic diffuse interstitial fibrosis, as well as suspected space-occupying lesions of the lungs, such as benign tumors, teratomas, malignant tumors, and alveolar proteinosis, and lung calculi, and also include bronchial asthma. If it is clear that the occupying lesion of the lung is a malignant tumor, such as bronchopulmonary carcinoma, alveolar cell carcinoma, etc., you should go to the oncology department for consultation. If there are various causes of respiratory distress in the lungs, severe dyspnea should go to the emergency department first.
