Abstract

Two electronic spirometers (Dräger Spirotron and Monaghan M403) and one wedge bellows spirometer (Vitalograph) were compared with a Bernstein spirometer. Healthy children, 30 girls and 31 boys, were investigated. The regression lines of VC and FEV1.0 in relation to the body height to the third power are very close and the S.D. values around the lines are very similar. The correlation coefficients of the regression lines are high for all the spirometers. An analysis of the paired differences showed slight differences of the mean values. The S.D. of paired differences was for VC 4.6--6.6% and for FEV1.0 4.8--6.2%. The PEFR values obtained by the two electronic spirometers deviated substantially and highly significantly from the values obtained by the Wright peak flow meter.

摘要

将两台电子肺活量计（德尔格肺功能仪和莫纳根M403）以及一台楔型风箱式肺活量计（维妥立）与伯恩斯坦肺活量计进行了比较。对30名女孩和31名男孩这些健康儿童进行了调查。肺活量（VC）和第一秒用力呼气量（FEV1.0）与身高的三次方的回归线非常接近，并且回归线周围的标准差（S.D.）值非常相似。所有肺活量计的回归线相关系数都很高。配对差异分析显示平均值存在细微差异。配对差异的标准差对于VC为4.6% - 6.6%，对于FEV1.0为4.8% - 6.2%。两台电子肺活量计测得的呼气峰值流速（PEFR）值与赖特峰值流量计测得的值有显著且高度显著的偏差。
