title: Changes in nasal airway resistance in response to controlled external respiratory obstruction.
abstract: A high degree of external nasal obstruction will by itself decrease nasal airway resistance. However, a controlled series of experiments in normal volunteers has shown that this lessened resistance is still not able to balance the level of the external obstruction present. The implications of this finding are discussed.
