Thermal Stimulation of the Oral Mucosa and Nasal Airway ResistanceDepartment of Physiology and Biophysics, Temple University School of Dentistry, Philadelphia, Pennsylvania 19140, USA
Department of Physiology and Biophysics, Temple University School of Dentistry, Philadelphia, Pennsylvania 19140, USA A procedure for measuring nasal airway resistance using posterior rhinorheotnetry is descrihed. Baseline nasal airway resistances ± 1 S.D. at an airflow of 0.5 L/sec were found to be 1.077 ± 0.683 cm H2O for inhalation and 1.359 ± 0.792 cm H 2O for exhalation. Application of either cold water (4 to 6 C) or warm water (44 to 52 C) to the oral mucosa significantly increased nasal airway resistance. Application of tepid water (26 to 28 C) did not alter nasal airway resistance significantly.
