title: The nasal provocation test in the diagnosis of allergic rhinitis. Behaviour and dynamics of nasal flow during the test.
abstract: We analyzed the value of the (n) coefficient of nasal flow in the formula of nasal resistances in order to: (1) calculate nasal flow during the course of the nasal provocation test, and (2) try to find out whether nasal flow maintains the same characteristics during the test. Our results show that values vary between 1.6589 and 1.8801, with a weighted mean of 1.7645--suggesting that the flow is of a mixed character--without significant differences during the course of the test. At the same time we carried out an analysis of the dynamics of nasal flow during nasal provocation.
