目前慢性阻塞性肺疾病(COPD)的诊断标准是应用支气管舒张剂后肺功能检查第1秒用力呼气容积(FEV 1)/用力肺活量(FVC)<70%,则确定存在持续性气流受限。但这一诊断标准对于老年人或可造成过度诊断,且操作过程中偶可出现咳嗽、胸闷、晕厥、呼吸困难等并发症。因此近年来对肺功能检查中其他指标的相关研究表明,FEV 1/FEV ...
Thus, an FEV(1)/FVC ratio <70% is used to diagnose COPD, and the severity is thereafter based on the level of FEV(1). This definition is widely... DS Postma,G Brusselle,A Bush,... - 《Thorax》 被引量: 41发表: 2012年 Researchers Examine Effects of Dietary Magnesium on Type 2 ...

/用力肺活量(FVC)<70%,则确定存在持续性气流受限.但这一诊断标准对于老年人或可造成过度诊断,且操作过程中偶可出现咳嗽、胸闷、晕厥、呼吸困难等并发症.因此近年来对肺功能检查中其他指标的相关研究表明,FEV1/FEV6、FEV3/FVC在气流受限的筛查、诊断中发挥了重要作用,并建议将FEV1/FEV6、FEV3/FVC作为筛检COPD的...

Objective To compare FEV 1 with FEV 1/FVC as judging criteria for airflow obstruction of COPD.Methods We prospectively analyzed the results of pulmonary function tests in 158 patients with chronic bronchitis and emphysema,34 patients with restrictive ventilatory dysfunction and 34 healthy persons.Result...
We found a positive correlation coefficient (r = 0.972, p < 0.001) between the FEV1/FEV6 and FEV1/FVC ratios and the cut off value of 71.845 (p < 0.01) for the post-bronchodilator FEV1/FEV6 ratio for the diagnosis of COPD. Thus FEV1/FEV6 should be used as a surrogate for FEV1/FVC...
ratio,especially in those COPD patients because it is not as a good parameter as FEV_1 which has very good trend and parallel with the severity of COPD.It lacks of enough theoretical evidence when only using FEV_1/FVC70 % for initial diagnosis and assessing the severity of COPD since it ...
