Emphysema can be distinguished from pleural effusion and from aneurism, which may cause dyspnoea, by the universal hyper-resonance on percussion. Pleural effusion, which also causes bulging, is usually unilateral, and the percussion-note is flat. The area of dulness of the heart and aorta is diminished in emphysema. Pneumothorax, which most resembles emphysema in its physical signs, develops suddenly, affects one side, and has a hollow, tympanitic note on percussion. The succussion-splash, metallic tinkling, and coin-test have no counterpart in emphysema; moreover, the antecedent history and mode of development are different. Atrophic emphysema is due to the degeneration of age. The lung is reduced in size. The diameters of the chest are lessened. The ribs are oblique. There is atrophy of the chest-muscles. The patients have dyspnoea. There are other signs of senility. In interlobular emphysema the physical signs are the same as those of vesicular emphysema, but it develops suddenly and is liable to be followed by emphysema (intercellular) of the neck, which on palpation gives a peculiar crepitation. The friction-sound and crackling which have been described as occasional adventitious sounds in vesicular emphysema arc more commonly heard in the interlobular form. It is caused by rupture of the air-cells, and hence occurs in diseases in which a great strain is put upon them--especially, therefore, in whooping-cough, but also occasionally in pulmonary hemorrhage and pneumonia; violent coughing and laughing, and...show more
