Abstract
The mucociliary system is one of the most important airway defense mechanisms, and knowledge of the ciliary beat frequency(CBF) is important in the understanding of this system. Using a laser light scattering method and fiber optic probe, we developed a simple and practical instrument for real-time in vivo measurements of CBF of cells in human nasal cavity. From the ciliated epithelium cells in an anterior end of middle terminator in nasal cavity, the signals of ciliary movement are transferred into a PC and analyzed by a autoregressive(AR) power spectrum. The mean CBF of 8 normal subjects was
