Abstract

Even 50% of population suffers from allergic symptoms in some countries. There is a need for an objective measurement method giving an accurate, reliable and continuous measurement data about the dynamic nasal function. A novel method to assess unobtrusively the continuous nasal airflow resistance using calibrated respiratory belts is used to produce a continuous nasal airflow resistance during the birch pollen provocation test. Ten birch pollen allergic and eleven non-allergic volunteers were recruited and measured. A statistically significant change in the nasal airflow resistance was found due to the challenge in the allergic group while no statistically significant change was found in the non-allergic group. Unique continuous nasal airflow resistance curves were derived to show the dynamic changes in the nasal airflow resistance during the provocation test. The continuous curves show in great detail fast and slow reactions to nasal provocations, which may be helpful in studying the reactivity of patients. The presented method could increase the reliability and accuracy of diagnostics and assessment of the effect of nasal treatments.
