Abstract
We have measured nasal mucociliary transport rates once in 58 subjects and, in 22 of these, three additional times at intervals of two hours. The study was performed under controlled climatic conditions (with a temperature of 23 C and relative humidity of 68%). The subjects could be classified in three groups: 32 who had a rapid uninterrupted particle movement, 14 who had a stop or slowdown in particle movement after an initial normal flow, and 10 who had either a constantly slow particle movement or stasis during the experiment. The transport rates in the first group ranged from 0.23 to 2.36 cm min-1, with an average of 0.84 cm min-1. In the subjects studied four times at two-hour intervals, some exhibited marked changes in transport rates during the eight-hour day.Keywords
