Objective: Nasal obstruction can be measured objectively by rhinomanometry and acoustic rhinometry, both complex techniques. Peak nasal inspiratory flow (PNIF) is also a tool for evaluating nasal obstruction. This study aimed to establish normal PNIF ranges for an Asian population accounting for sex, age, weight, and height. Methods: Using a portable Youlten peak flowmeter, PNIF was measured in 180 healthy Thais (ages 15-70 years). Normal ranges for male and female subjects, adjusted for weight and height, were determined using multiple regression analysis. Results: Body mass index values (mean ± S.D.) of the 82 male and 98 female subjects were 24.9 ± 4.5 and 21.7 ± 4.3 kg/m2 , respectively. PNIF was significantly higher in males than in females (139 ± 37.6 vs. 97.1 ± 27.1 l/ min, p |
