1. A method of assessment of airway variability in airway responsiveness or asthma comprising the steps of:

  • 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.
