Abstract:
In 36 patients inspiratory and expiratory pressures in the pharynx were measured during nCPAP with pressures ranging from 5 to 20 mbar. The results were compared to the nasal resistance as measured by rhinomanometry and to minimal cross-sectional area of the nose as measured by acoustic rhinometry.
