Abstract
The changes of the intranasal and ear canal pressure on swallowing during jet nebulizer therapy are studied. Intranasal pressure was temporarily increased on swallowing during nebulizer therapy, and it grew greater as the flow rate of nebulizer increased. Maximum change of intranasal pressure on swallowing in this study was about 20 cmH2O. The ear canal pressure was slightly increased with the change of intranasal pressure on swallowing.
These results suggest that swallowing movement during jet nebulizer therapy is effective to induce the aerosol particles to the paranasal cavities, and that therapy may also be effective to the lesion in the tuba auditiva and tympanic cavity. It should be considered that swallowing is an easy method to make nebulizer therapy for the paranasal and tympanic cavities more effective.
