定义
肺气肿的定义是终末细支气管远端的气腔隙异常和永久性增大。这伴随着腔隙壁的破坏，没有明显纤维化（即肉眼看不到纤维化）。没有气流阻塞的人也可能存在肺气肿；然而，它在中度或重度气流阻塞的患者中更为常见。
Emphysema is defined by abnormal and permanent enlargement of the airspaces that are distal to the terminal bronchioles. This is accompanied by destruction of the airspace walls, without obvious fibrosis (i.e. there is no fibrosis visible to the naked eye). Emphysema can exist in individuals who do not have airflow obstruction; however, it is more common among patients who have moderate or severe airflow obstruction.
