Abstract:
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.
