  • Method of assessment of airway variability in airway hyperresponsiveness
    Publication number: 20050247307
    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.

  • Measurement of airway calibre
    Patent number: 6074350
    Abstract: The variation in flow resistance of the respiratory system (Rrs) is determined as an indicator of variations in airway calibre, by oscillating the system, for example at 6 Hz for 5-15 minutes and determining the variations in ratio of the pressure difference (Prs) across the system that is in phase with flow, to flow V. The variation in airway calibre may be employed as a prognostic indicator in asthmatics and also to assess the efficacy of treatment.
