Abstract/OtherAbstract:
|
Rhinomanometry is a method for measuring nasal resistance for the purpose of providing an objective evaluation of nasal patency. Posterior rhinomanometry is accomplished without the use of a mask, thus allowing the patient to breathe naturally. Here, we report on the improvements we have made to the existing posterior rhinomanometry system. In this system, nasal airflow is measured indirectly by measuring the pressure differential across a small mesh window in the body plethysmograph. We have calibrated this measurement and developed software that automatically provides the correct values for all airflow rates. Also, we have developed software that automatically corrects for the phase shift caused by the plethysmograph structure. These refinements should provide more accurate values for nasal resistance. |
