Abstract
A non-invasive method and apparatus for monitoring individual lung function is disclosed. A transducer (12, 14) is disposed on the torso above the lung to be monitored, the transducer producing a signal corresponding to movement of the torso portion therebeneath which, in turn, corresponds to changes in the volume of the underlying lung. Regional lung volume changes may also be assessed by utilizing transducers positioned on the torso to encompass only a portion of the underlying lung.
