Effect Of Testing Technique On Nasal Pressure Variation

Abstract

The effect on nasal pressure change of breathing through a mask was studied in supine position by anterior rhinomanometry. Irrespective of the effect of shrinking drugs or the anatomical or functional health of the nose, a significant increase was observed in both inspiratory pressure fall and expiratory pressure rise when testees were breathing through a mask. In a majority of cases, an increase in pressure change was observed leading to a different clinical result. Intensive studies of all technical details is recommended before a testing technique is adapted.
