Vibration during chest physiotherapy creates small - amplitude, high - frequency tremors that increase air turbulence during exhalation, helping to mobilize and expectorate thick pulmonary secretions. Percussion is mainly for loosening secretions by rhythmic tapping. Nebulization is for delivering medication in aerosol form. Postural drainage uses body positions to facilitate secretion drainage.
