airway responsiveness

airway responsiveness

The degree to which airways respond to various stimuli, including inhaled agents (such as histamine and methacholine) and physical stimuli (such as exercise). Airway responsiveness is commonly assessed by measuring lung function before and after inhalation of increasing concentrations of a “trigger” such as methacholine.
