Figure 5: Dynamic changes of airway inner area and
airway wall thickness percentage after salbutamol inhalation.
(A) The average changes of Ai from the 3rd to
9th generation of bronchi. (B) The average changes of
Aw% of medium and small airways.
* Compared with baseline, P<0.05.
Abbreviation: Ai: airway inner area; BSA: body surface area;
Aw%: airway wall area percentage; gen: generation of bronchi.
