Abstract

Eight cases have been studied in which both lung function and histological morphometric data was available on divers' lungs. A correlation was found between the increase in forced vital capacity measured at routine annual medical examination and the morphometric measurement of alveoli by mean cord length. The results suggest that reduction of forced expiratory volume in one second may be due to narrowing of small airways by distention of the alveoli.

摘要

已对8例潜水员肺部进行了研究,这些潜水员均同时具备肺功能和组织形态计量学数据。在常规年度体检中测得的用力肺活量增加与通过平均弦长对肺泡进行的形态计量学测量之间发现了相关性。结果表明,一秒用力呼气量的降低可能是由于肺泡扩张导致小气道变窄所致。
