Physiologic Correlates of Increased Airway Responsiveness
The airway caliber change that occurs immediately following a deep inhalation (DI) in asthmatic subjects varies. There may be a decrease in airway caliber — i.e. bronchial constriction — or there may be no change, or dilation of the airways may occur. I would like briefly to review data which support the idea that when the clinical state and the stimulus used to produce bronchial obstruction are considered, there is a pattern that might be of value clinically and epidemiologically.
