Figure 3: Changes of Ai/BSA from the 3rd to
9th generation of bronchi in response to salbutamol
inhalation in each individual (n=32)
The average Ai/BSA at 10th and 15thmin after bronchodilation were significantly increased, compared with
the Ai/BSA obtained at 1st min (allP <0.05).
Abbreviation: Ai: airway inner area; BSA: body surface area.
