title: The arts of percussion and auscultation of the chest re-examined.
abstract: Clinical teaching of percussion and auscultation is examined critically, and it is suggested that there is confusion on the subject both in textbooks and in the minds of clinicians and students. Percussion should be viewed more in terms of 'feel' than 'sound', and thus a classification of 'hard', 'intermediate' and 'soft' dullness is introduced. As regards auscultation, a plea is made for differentiation between obstructed and non-obstructed consolidation of lobes, a point recognized by some clinicians, but not enunciated with clarity by teachers. The differences between the clinical findings in obstructive consolidation of the upper and lower lobes are discussed. The importance of distinguishing between tracheal and bronchial breathing is emphasized.
