慢性阻塞性肺疾病 (COPD)

目前尚无数据最终证实肺量测定筛查可有效指导管理决策或改善无症状患者的 COPD 结局，美国预防服务工作组（US Preventive Services Task Force, USPSTF）建议勿对此类人群进行筛查。[56]US Preventive Services Task Force. Final recommendation statement. Chronic obstructive pulmonary disease: screening. May 2022 [internet publication]. https://www.uspreventiveservicestaskforce.org/uspstf/recommendation/chronic-obstructive-pulmonary-disease-screening 但是，如果COPD在早期诊断出来并去除危险因素，肺功能下降速率将显著延缓。[57]Welte T, Vogelmeier C, Papi A.

慢性阻塞性肺疾病全球倡议（Global Initiative for Chronic Obstructive Lung Disease, GOLD）指南主张通过对有 COPD 症状和/或危险因素的患者进行肺量测定，早期发现病例。[1]Global Initiative for Chronic Obstructive Lung Disease (GOLD).
