Overview
Other diagnostic tools that can be used are pulmonary function tests, electron microscope examination, and bronchoscopy.
Bronchiectasis Other Diagnostic Studies
Pulmonary Function Tests
- Early in the disease, patients will present with pulmonary function tests that represent an obstructive disorder (FEV1/FVC ratio <80%)
- This indicates the inflammation and involvement of the small airways
- As the disease progresses, the pulmonary function tests represent a restrictive disorder (FEV1/FVC ratio > or = 80%)
- This indicates the destruction of the lung tissue and small airways
- The forced expiratory volume in one second (FEV1), forced vital capacity (FVC), and peak expiratory flow (PEF) should be measured annually
- If the patient has an immune deficiency or primary ciliary dyskinesia, then the above should be measured four times a year
Electron Microscope Examination
- Examination can be performed on sputum and respiratory epithelium for evidence of ciliary structural abnormalities or dyskinesia
Bronchoscopy
- Bronchoscopy with bronchoalveolar lavage may be used to obtain specimens for staining and culture[1]
