Pulmonology, also called respiratory medicine, covers airway, lung-parenchymal and pleural disease. Evaluation may use symptoms, examination, chest imaging, pulmonary-function testing, microbiology and tissue sampling. Interventional pulmonology adds flexible or rigid bronchoscopy, ultrasound-guided sampling, airway treatment and selected pleural procedures.
A procedure should answer a defined question or solve a defined problem. Bronchoscopy can inspect the airway and obtain washings or tissue. EBUS and needle aspiration sample structures beside the airway. Transbronchial biopsy and cryobiopsy obtain peripheral lung tissue with different specimen sizes and risks. Thoracoscopy or pleuroscopy examines the pleural space. Therapeutic procedures may restore an obstructed airway or drain pleural fluid.
Technique and setting depend on oxygen reserve, airway anatomy, target location, bleeding and pneumothorax risk, anticoagulants, anaesthetic needs and available rescue support. A respiratory physician may coordinate with thoracic surgery, oncology, radiology, pathology, microbiology, critical care and transplant teams. Catalog relationships do not establish that every listed service is available at every hospital.
