摘要： 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.
