Abstract

Five spirometers were compared with the Stead-Wells spirometer in 100 subjects, using the FVC and FEV1 as parameters. In addition, some physical characteristics were studied. The Stead-Wells is a water-sealed spirometer, recommended as a reference spirometer by the American Committees on Environmental Health and Respiratory Physiology. The Vicatest and Vitalograph are volume-displacement dry spirometers. They showed a very good linearity over their entire volume ranges; their FVC and FEV1 readings showed very good correlations with the readings of the Stead-Wells spirometer. The Monaghan, Pneumoscreen, and Spirotron are flow-integrating "electronic" spirometers. The volumes recorded were found to be dependent on the values of the flow; their FVC and FEV1 readings also showed good correlations with the readings of the Stead-Wells spirometer, but to a lesser extent than the two dry spirometers. Therefore, for routine assessment of ventilatory function we prefer, at present, the modern volume-displacement dry spirometers.

摘要

以用力肺活量（FVC）和第一秒用力呼气容积（FEV1）作为参数，将五台肺量计与100名受试者的Stead-Wells肺量计进行了比较。此外，还研究了一些身体特征。Stead-Wells是一种水封式肺量计，被美国环境卫生与呼吸生理学委员会推荐为参考肺量计。Vicatest和Vitalograph是容积置换干式肺量计。它们在整个容积范围内显示出非常好的线性；它们的FVC和FEV1读数与Stead-Wells肺量计的读数显示出非常好的相关性。Monaghan、Pneumoscreen和Spirotron是流量积分“电子”肺量计。发现记录的容积取决于流量值；它们的FVC和FEV1读数与Stead-Wells肺量计的读数也显示出良好的相关性，但程度低于两台干式肺量计。因此，就通气功能的常规评估而言，目前我们更倾向于现代容积置换干式肺量计。
