Pulmonary e. due to defective expansibility of some other portion of the lung, the portion in which the e. develops giving way under the influence of atmospheric pre ure through the air-pa ages. [Kor (A, 319).] E. abdominale, E. abdominis. See TYMPANITES. E. ceilulare. See Subcutaneous e. E. conjunctiva'. Fr., emphyseme de la conjunctive. Ger., Bindehautemphysem. li.,enfisemadvllacongiuntiva. Sp., enfisema de la conjuntiva. A collection of air beneath the conjunctiva. [F.] E.orbitas. Fr., emphyseme deV or bite. Ger., Emphysem der Augenhohle. A collection of air in the meshes of the orbital ti ue, almost always accompanied by e. of the lids. [F.] E. pulmonum. See Pulmonary e. E. tympan it i cum. See TYMPANITES. E. uni ver sale. General subcutaneous e. [L, 128.] E. uterinum. See PIIYSOMETRA. E. vagans. A form of subcutaneous e. in which the collection of air shifts from one part to another. [L, 128.] E. vaginae. See COLPO-HYPERPLASIA cystic a. Extra-alveolar e., Extra-vesicular e. See Interlobular e. False e. See Spontaneous e. Interlobular e. Fr., emphyseme interlobulaire. Ger., Interlobularemphysem. That form of pulmonary e. in which, from the rupture of one or more air-vesicles, air is forced into the connective ti ue between the lobules, generally near the apex of the lung, and forms pouches of various sizes. [Koranyi (A, 319).] Mediastinal e. Distension of the mediastinum with air; usually from rupture of the sacs formed in interlobular pulmonary e. [Koranyi (A, 319).] Pulmonary e. Lat., e. pidmonum. Fr., emphyseme pulmonaire. Ger., Lungenemphysem. E. of the lung. See Interlobular e. and Vesicular e. Senile e. Fr., emphyseme senile. Ger., seniles Emphysem. The pulmonary e. of the aged; usually preceded by diminished mobility of the ribs. [Koranyi (A, 319).] Spontaneous e. Subcutaneous e. dependent on gangrene. [A, 319.] Subcutaneous e. Fr., emphyseme souscutane. Ger., Hautemphysem. Distension of the subcutaneous connective ti ue with air. Sub pleural e. Interlobular pulmonary e. occurring immediately beneath the pleura. [Koranyi (A, 319).] Substantive e. Fr., emphyseme substantif. Ger., substantielles Emphysem. Pulmonary e. in which the a tropic changes in the alveolar walls are a prominent feature. [Koranyi (A, 319).] Surgical e., Traumatic e. Subcutaneous e. due to traumatism. Vesicular e. Fr., emphyseme vesicula ire. Ger., Vesicularemphysem. Of Laennec, that form of pulmonary e. which consists in abnormal dilatation of the air-vesicles and consequent over-accumulation of air. It may come on gradually or suddenly (as from playing upon a wind instrument). As the air-vesicles coalesce, the interstitial ti ue and its blood-ve els are effaced and the nutrition of the lung is consequently impoverished. Dyspnoea is a marked symptom of the disease, and there is a tendency to ultimate dilatation of the right side of the heart and dropsical effusions. [D, 1.] Vicarious e. See Compensatory e. [s. 691]
