Effect of low frequency air oscillations on nasal mucociliary transport.
Air oscillations of 16 Hz and pressure differences of 200 mmHg were applied to the nose of 30 volunteers. The mucociliary transport was measured by the saccharin test. Tests under the same circumstances were performed with and without oscillations on the same person within the same day. There was a significantly faster mucociliary transport during air oscillations. The possible mechanisms for this effect are discussed.
