肺功能检查与肺间质疾病

Pulmonary function test and pulmonary interstitial disease

肺间质疾病(interstitial lung diseases,ILD)是一组异质性疾病,以静息状态限制性通气功能障碍和运动诱发低氧血症为特征。多数ILD的肺功能异常具有共同特征,但无特异性。肺功能检查对诊断疑似ILD患者具有重要意义,对于确诊ILD病例,肺功能可以评估疾病的严重程度,并监测疾病的演变。

Interstitial lung diseases (ILD) are a heterogeneous group of disorders, which are functionally cha-racterized by a restrictive ventilatory defect and exercise induced hypoxemia.Most lung function abnormalities in ILD share common features but are not specific.Pulmonary function is important for the diagnosis of patients with suspected ILD.For the diagnosis of ILD cases, pulmonary function test can assess the severity of the diseases and monitor progre-ssion of diseases.
