[Measuring nasal resistance using passive anterior rhinomanometry. Results in normal subjects, bronchially hyperreactive and manifestly obstructed patients].

The values of nasal resistance measured by passive, anterior rhinomanometry are reported. The results of measurements on a group of healthy probands correlate significantly with those gained by wholebody-plethysmography. Three of four patients with bronchial hyperreactivity, on acetylcholine, had an increase of nasal resistance after endonasal application of this agents. Ten patients with 'COLD' had normal nasal resistance values; no increase of the values could be demonstrated, after local acetylcholine application.
