Answer

Peripheral airway inflammation and obstruction are signaled by increased resistance at low (5 cycles/s) oscillation frequencies that are decreased at higher oscillation frequencies (15 or 20 cycles/s). In association with the fall in resistance from 5-15 cycles per second, the magnitude of respiratory reactance in peripheral airway inflammation and obstruction increases.
