Relationships between vital capacity, height and nasal airway resistance in asymptomatic volunteers.
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.
