Diseases of Small Airways of lung
نویسنده
چکیده
Small airways offer 1/4th of the total airways resistance. Disease of small airways results from exposure to tobacco smoke, mineral dust, air-pollutants, and viral infections. It may also be associated with connective tissue disorders or may follow bone marrow, lung, or heart-lung transplantation. The pulmonary function tests are deranged late in the disease and the damage done is irreversible. Therefore, management lies in preventing exposure to smoke and dust, whether in the form of smoking tobacco or exposure to industrial dusts in the work environment.

Dysfunctional lung anatomy and small airways degeneration in COPD
Chronic obstructive pulmonary disease (COPD) is characterized by incompletely reversible airflow obstruction. Direct measurement of airways resistance using invasive techniques has revealed that the site of obstruction is located in the small conducting airways, ie, bronchioles with a diameter < 2 mm. Anatomical changes in these airways include structural abnormalities of the conducting airways...

متن کاملTechniques of assessing small airways dysfunction
The small airways are defined as those less than 2 mm in diameter. They are a major site of pathology in many lung diseases, not least chronic obstructive pulmonary disease (COPD) and asthma. The small airways are frequently involved early in the course of these diseases, with significant pathology demonstrable often before the onset of symptoms or changes in spirometry and imaging. Despite the...
