Abstract:
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.

Respiratory Capacities
One key metric is the Inspiratory Capacity (IC), which represents the maximum amount of air that can be inhaled with full effort. IC is calculated by summing the tidal volume and inspiratory reserve volume, typically ranging from 2.4 to 3.6 liters.

Alveolar Surface Tension
The alveolar fluid lines the luminal surface of the alveoli and exerts a force called surface tension. This force is caused by the polar water molecules in the liquid being more strongly attracted to each...
