In 432 electric welders and 420 not respiratory exposed workers the information value of spirometry (VC, FEV1) and flow volume curves (PEF, V2/V1, V50, V75) was examined taking into consideration the influence of age, smoking and occupational exposure. Despite the higher frequency of chronic bronchitis and pulmonary siderosis in exposed workers no influence of welding fumes on the above mentioned parameters could be shown. Comparing different smoking groups all parameters (with the exception of VC) exhibited the same trend, the FEV1 at the top regarding significance and weight. These results don't support a wider use of flow volume curves in the screening of not selected groups of different exposure. Whether the compared methods can lead to different qualitative or prognostic informations should be examined further in studies comparing functional and morphological data and in epidemiological follow-up studies.
在432名电焊工和420名无呼吸道暴露的工人中，考虑到年龄、吸烟和职业暴露的影响，对肺活量测定（VC、FEV1）和流量容积曲线（PEF、V2/V1、V50、V75）的信息价值进行了研究。尽管暴露工人中慢性支气管炎和肺铁末沉着症的发生率较高，但未显示出焊接烟雾对上述参数有影响。比较不同吸烟组时，所有参数（VC除外）均呈现相同趋势，其中FEV1在显著性和权重方面最为突出。这些结果不支持在未筛选的不同暴露人群筛查中更广泛地使用流量容积曲线。比较的方法是否会导致不同的定性或预后信息，应在比较功能和形态学数据的研究以及流行病学随访研究中进一步探讨。
