摘要
目的通过临床病例肺功能结果分析对目前临床应用的肺功能不全分级标准进行探讨。方法对77例临床病例肺功能结果按不同指标进行分级,根据其临床特点和肺功能指标进行分型,分别用肺功能不全分级标准等再次进行分级并观察不同标准之间的符合情况。结果77例肺功能结果按肺功能不全分级表中肺活量(VC)实测值/预计值指标和第一秒钟用力呼气容积(FEV1)/用力肺活量(FVC)指标分别进行分级,按两标准分级完全一致的有16例,占20.77%;77例中符合阻塞型通气功能障碍特点者52例,符合限制型通气功能障碍特点者25例,不同方法分级符合率显示:阻塞型通气功能障碍组FEV1/FVC法与慢性阻塞性肺疾病分级标准符合率为67.30%,优于其他方法间比较。结论阻塞型通气功能障碍分级标准中需加入气道阻力、残气/肺总量等指标,使分级更准确,限制型通气功能障碍的分级是否需肺总量(TLC)和VC两指标加以限定,有待深入研究。
Objective To study the necessity of modifying the staging criteria for pulmonary disfunction on the basis of clinical analysis of 77 cases. Methods The pulmonary function tests were performed in 77 cases and were classified by different criteria. The consistencies and differences of the stage and severity judged by different criteria were analyzed and compared. Results According to different staging criteria the severity of pulmonary disfunction in 16（20.77 % ） cases were consistent （VC and FEV1/FVC）. The cases were further classified as obstructive disfunction （52 cases ） and restrictive disfucntion （25 cases）. The results showed that there was better consistency（67.30% ） between the criteria based on FEV1/FVC and the diagnostic criteria for chronic obstructive pulmunary disease（COPD） in obstructive cases. Conclusions It is necessary to include airway resistance（Raw）, residual volume/total lung volume（RV/TLC） in order to make more accurate stage for obstructive pulmonary disfunction. However it is uncertain whether the present staging criteria for restrictive disfunction should be modified by TLC and VC.
