肺功能检查在慢性阻塞性肺疾病诊断中的应用

Application of the pulmonary function tests in diagnosis of chronic obstructive pulmonary disease

目的评价肺功能检测在慢性阻塞性肺疾病(COPD)诊断中的应用。方法我院呼吸内科2010年1月～2011年1月接受肺功能检查的患者共1036例,进行临床和肺功能诊断,并对COPD进行分级。结果 1036例患者中,共诊断出128例COPD患者,漏诊27例,误诊28例,漏诊率和误诊率分别为21.87%和21.26%。COPD轻度、中度、重度和极重度与对照组的FEV1(%)和FEV1/FVC(%)差异有统计学意义(P<0.05)。并且FEV1(%)和FEV1/FVC(%)随COPD的严重程度呈现逐渐降低趋势,并且趋势性检验P<0.05。结论肺功能检查在COPD诊断中具有重要的意义,临床上肺功能检查的应用能帮助COPD进行早期诊断、早期治疗。

Objective To evaluate the pulmonary function tests in diagnosis of chronic obstructive pulmonary disease.MethodsA total of 1036 patients were collected in respiratory department from January 2010 to January 2011,and clinic diagnosis and pulmonary function tests was performed to them.ResultsAmong 1036 patients,a total 128 COPD patients were diagnosed,and 27 patients were omission diagnosis and 28 patients were misdiagnosis,with the rates of 21.87% and 21.26%,respectively.There were significant difference in the FEV1（%）and FEV1/FVC（%） rates from mild to very severe COPD and controls（P〈0.05）.The FEV1（%）and FEV1/FVC（%） rates showed decreased trend with the serious condition of COPD（P〈0.05）.ConclusionThe pulmonary function test has important role in diagnosis of COPD,and it could help early diagnosis and treatment of COPD.
