title: Measurement of nasal air flow with a new apparatus.
abstract: An apparatus for measurement of nasal air flow has been calibrated against pressure-flow curves obtained in a pneumotachograph. A very high degree of correlation and an error of less than 3% of baseline values resulted when the apparatus was tested in hay fever patients using nasal allergen challenge.
