Allergic Rhinitis: 243 Peak Inspiratory Flow Rate is More Sensitive Than Acoustic Rhinometry or Rhinomanometry in Detecting Nasal Obstruction Using the Allergen Challenge Chamber

摘要

BackgroundWe prepared an allergen challenge chamber (ACC) which facilitates quantitative pollen challenge at any time, and, so, the acquisition of objective data. The aim of this study was to evaluate peak nasal inspiratory flow rate (PIFR) as an endpoint during allergen challenge and compare this with rhinomanometry (Rhino) and acoustic rhinometry (AR).
