COPD是一种常见的以持续性呼吸系统症状和气流受限为特征的可以预防和治疗的疾病,呼吸道症状和气流受限是由有毒颗粒或气体导致的气道和/或肺泡异常引起的[1]。由于发展中国家的高吸烟率,COPD患病率的快速增长和随之而来的负担正在迅速上升。WHO预测,到2030年它将成为死亡的第3大原因[2]。

The FEV1/FEV6ratio can be used as a valid alternative for FEV1/FVC in the diagnosis of airway obstruction, especially for screening purposes in high-risk populations for COPD in primary care. In addition, FEV6is an acceptable surrogate for FVC in the detection of a spirometric restrictive ...
