Abstract
An apparatus for dislodging or loosening mucus in a person's lungs, for example of a sufferer of cystic fibrosis, comprises a bath arranged to receive the person and filled with water such that the person's chest is immersed in the water. A vibrator vibrates the liquid so that the vibrations are transmitted to the person's lungs. In use the vibrations are preferably at the pulmonary resonant frequency or Helmholtz resonant frequency of the person's lungs.

An apparatus for dislodging or loosening mucus in a person's lungs, comprising:
- a bath arranged to receive the person and a liquid such that the person's chest is immersed in tie liquid;
- means for vibrating the liquid so that the vibrations are transmitted to the person's lungs;
- means for detecting a level of vibrations to produce a detection signal;
- means for attaching the detecting means to the person's chest so as to detect a level of the vibrations transmitted to the person's lungs;
- and
- means responsive to the detection signal for adjusting the frequency of the vibrations produced by the vibrating means so that the frequency of the vibrations approximates a resonant frequency of the person's lungs.
