A module for an oscillometry system of the type having an oscillatory flow source, the module comprises an enclosure adapted to be releasably connected to a core assembly of the oscillometry system. The enclosure defines a breathing flow pathway adapted to be in fluid communication with the oscillatory flow source. A user port is at a first end of the breathing flow pathway configured for receiving a breath of a user. A calibration file specific to the module is programmed as a function of the breathing flow pathway and configured for being used by the oscillometry system to assess breathing parameters for the user.

The invention relates to a method of assessing airway variability in airway responsiveness or asthma by measuring the variation of resistance (Rrs) by a forced oscillation technique utilizing either a single or a plurality of input frequencies during a plurality of respiratory cycles of a patient; calculating the statistical variability of the Rrs for the patient; and, correlating the statistical variability of the Rrs of the patient to a standard curve to quantify the degree of asthma of the patient. The invention also enables the effectiveness of a bronchoactive agent to be measured.
