Abstract

Measuring the nasal airflow during quiet respiration can be used for screening, diagnosis, and assessment of treatment of the upper respiratory system. It also gives information about the lower respiratory system such as lung capacity. Spirometer can be replaced by the nasal anemometer with the technique of measuring nasal airflow during forced respiration. To fulfill these functions, the nasal anemometer using the quiet respiration technique must be standardized. Measurement of airflow during quiet respiration has been carried out on 50 male normal subjects. A range of some parameters has been defined. These parameters are time of one respiratory period, the maximum of respiratory signal, and average amount airflow signal in 10 respirations.
