To measure nasal patency, various kinds of rhinomanometry are used by many reserchers. Obtaining not only standard values of nasal patency but also standardized techniques for rhinomanometry is important.<BR>To evaluate nasal obstru c tion, a computer analyzing system (NI-101) was developed in our clinic. This system can demonstrate, (1) nasal airflow, pressure, and resistance curves; (2) the active values of these parameters at any point during the nasal re spiratory cycle; (3) Lissajous figure between airflow and pressure; and (4) the Peak Flow Index on a TV screen. This system also has a new program to calculate the acceleration of these parameters, and plot them on the original parameter curves as the acceleration curve on a time axis.<BR>In this paper, we describe this computer system and demonstrate the data obtained from a healthy control and a patient with nasal polyp. From these data, this system appears useful for objective evaluation of nasal obstruction.
