Nasal airway resistance (NAR), vital capacity and height were measured in 76 asymptomatic volunteers aged between 18 and 71, mean age 28 +/- 1.4 years. Total NAR ranged from 0.15-0.39 Pa/cm3/s, with a mean total NAR of 0.23 +/- 0.006 Pa/cm3/s. Despite a good correlation between vital capacity and height in these subjects (r = 0.76) no relationships were found between either total NAR and vital capacity or total NAR and height. Physiological NAR is not related to vital capacity or height in normal healthy individuals.
