Contraction of Left Chest. Empyema. INSPECTION. 73 ing, especially but not exclusively when the fever is associated witha disease of the heart, lung, pleura, or pericardium. Sucking-in of the interspaces in the lower axillary regions or below the clavicles maybe seen in connectionwith dyspnoea when-ever the lungs are pre-vented by some causefrom properly expand-ing during inspiration.Negative pressure i sthus produced withinthe chest, and the at-mospheric pressurewithout pushes in themore elastic parts ofthe thorax. This phe-nomenon is seen in. col-lapse or atelectasis ofa portion or the wholeof a lung, such as mayoccur in obstruction atthe glottis (in whichcase both sides areequally retracted) o rfrom occlusion of abronchus. In the lat-ter event, the sucking-in of the interspaces during inspiration oc-curs only on the affected side.1 1 Slight retraction of the lower interspaces in the axilla during inspirationis often seen in health. In disease this phenomenon is greatly exaggerated.

Fig. 53.— Prominence of Eight Side. Pleural Effusion. 74 PHYSICAL DIAGNOSIS. V. Changes in the Respiratory Rhythm. (a) Asthmatic Breathing. In asthma the normal rhythm is reversed and the expirationbecomes longer, instead of shorter, than inspiration. Inspirationmay be represented only by a short gasp, while expiration becomesa prolonged wheeze lasting several times as long as inspiration.Dyspnoea is usually very marked. In emphysema we get verymuch the same type of breathing so far as rhythm is concerned,but the dyspnoea is not usually so extreme and the auxiliary mus-cles of respiration are not so apt to be called into use. In manycases of emphysema one sees the thorax move all as one piece, encuirasse, owing to a senile fixation of the bones of the thorax fromossification of the cartilaginous portions. In hereditary syphilis orphthisis this fixation may occur in youth or early middle age. (fi). Cheyne-Stokes Breathing. An anomaly of respiratory rhythm in which short, recurrentpar
