Table 1 Mean mucus transport velocity (MTV) and cilia beat frequency (CBF) measurements under body temperature and fully saturated with water vapor (38 °C and relative humidity (RH)100%) and room air (22 °C and RH 50%) from each analyzed video

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

  1. Results are presented as the mean ± standard deviation. Time measurements represent the time the MTV and CBF took to change from measurements made at 38 °C and 100% RH to measurements made at 22 °C and RH 100%. The delay is the difference between the MTV and the CBF times taken for change
