Abstract

Environmental tobacco smoke (ETS) exposure is associated with rhinitis symptoms (i.e., runny nose and congestion) in some people. In an effort to better understand these symptoms, we recruited 18 historically ETS-sensitive subjects from the community and exposed them for 15 min to clean air and for 15 min to sidestream tobacco smoke (STS, 45 ppm carbon monoxide). Symptoms were recorded (0 = absent, 5 = severe), and posterior rhinomanometry was performed. There were significant changes in rhinitis symptoms (1.3 ± 0.4 pre- versus 6.1 ± 0.5 post-STS, p <.05); nasal airway resistance (2.86 ± 0.2 pre- versus 4.49 ± 0.6 post-STS, p <.05), and maximum inspiratory flow (2.74 ± 0.3 pre- versus 2.14 ± 0.3 post-STS, p <.05). A spectrum of individual responsiveness to ETS was observed, and nasal resistance increased from 0% to 265%. Increased nasal resistance occurred primarily at the upstream or flow-limiting segment of the nasal airway.
