Peak nasal inspiratory flow evaluation as an objective method of measuring nasal airflow.

Unlabelled: Acoustic rhinometry, rhinomanometry and Inspiratory Peak Nasal Flow (IPNF) are used in order to objectively assess nasal patency. These are expensive not very practical tests, except for IPNF, which is a fast, simple and low cost method.

Objective: To assess IPNF in healthy individuals complaining of nose obstruction caused by allergic rhinitis.
