Abstract:
This study examines calculations of model nasal cross-sectional area, using nasal versus oral pressure measurements. The results indicate that greater accuracy of nasal cross-sectional area estimation is achieved by using nasal rather than oral pressures. Nasal pressures measured in the anterior model nose more closely reflect nasopharyngeal pressures under a wide range of nasal constriction sizes and airflow rates.
