Techniques of assessing small airways dysfunction
W McNulty, OS Usmani - European clinical respiratory journal, 2014 - Taylor & Francis
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) …
