[Purpose] The purpose of our study was to investigate the effect of different positions on pulmonary function test (PFT) values such as forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) of asthmatic patients .[Subjects and Methods] Thirty subjects with severe asthma aged between 20-39 years were enrolled after they had signed a written consent. Subjects were selected using the inclusion criteria, and PFT were randomly administered. Spirometer measurements (FVC, FEV1) were taken in the supine, side lying on right, side lying on left, sitting and standing positions. Each measurement was taken three times, and the average values were analyzed. [Results] One- way analysis of variance (ANOVA) and Tukey's Test (post hoc) for pair- wise comparison indicated that there was a significant difference in the FEV1 values of the asthmatic patients however a significant difference was obtained between standing and supine positions. There was also a significant difference in the FVC values between the standing and supine lying position in the pair -wise comparison. [Conclusion] This study showed standing is the best position for measuring FEV1 and FVC of asthmatic subjects. The more upright the position, the higher the FEV1 and FVC will be.
[目的] 本研究旨在探讨不同体位对哮喘患者肺功能测试（PFT）值的影响，如用力肺活量（FVC）和一秒用力呼气量（FEV1）。[对象与方法] 30名年龄在20至39岁之间的重度哮喘患者在签署书面同意书后被纳入研究。根据纳入标准选择研究对象，并随机进行肺功能测试。在仰卧位、右侧卧位、左侧卧位、坐位和站立位进行肺活量计测量（FVC、FEV1）。每次测量进行三次，并分析平均值。[结果] 单向方差分析（ANOVA）和用于两两比较的Tukey检验（事后检验）表明，哮喘患者的FEV1值存在显著差异，然而站立位和仰卧位之间存在显著差异。在两两比较中，站立位和仰卧位之间的FVC值也存在显著差异。[结论] 本研究表明，站立位是测量哮喘患者FEV1和FVC的最佳体位。体位越直立，FEV1和FVC值越高。
