Table 2 Mean mucus transport velocity (MTV) and cilia beat frequency (CBF) measured under body temperature (38 °C) and fully saturated with water vapor (100% relative humidity) (Baseline) and following nebulization with 7% NaCl or 20% mannitol, entrained with the same air conditions

From: Rapid changes in mucociliary transport in the tracheal epithelium caused by unconditioned room air or nebulized hypertonic saline and mannitol are not determined by frequency of beating cilia

Nebulized solution Mucus transport velocity (mm/min) Cilia beat frequency (Hz)
