The characteristics and performance of the Vitalograph dry spirometer were studied using the criteria suggested by the International Labour Organisation (I.L.O.) Report on the standardization of respiratory function tests in pneumoconiosis. Comparison was also made with the Bernstein spirometer. The recorder speed, activation volume, and accuracy of volume calibration and linearity comply with most of the suggestions in the I.L.O. Report. The combined resistance and inertia of the Vitalograph exceed the limits cited in the report, however, and are also greater than those reported for the Bernstein and other spirometers. Nevertheless, the Vitalograph calibrates well against the Bernstein for vital capacity and FEV measurements made in normal subjects and in patients with obstructive airways disease. It is therefore suggested that it may be suitable for the assessment of forced expiratory volume and vital capacity in patients and normal subjects, or in population survey work. The fact that it is lightweight, portable, and robust is also an advantage.
使用国际劳工组织（I.L.O.）关于尘肺病呼吸功能测试标准化报告中建议的标准，对维达福干式肺活量计的特性和性能进行了研究。同时也与伯恩斯坦肺活量计进行了比较。记录器速度、启动体积以及体积校准的准确性和线性符合I.L.O.报告中的大多数建议。然而，维达福的综合阻力和惯性超过了报告中引用的限值，并且也大于伯恩斯坦和其他肺活量计报告的数值。尽管如此，在正常受试者和阻塞性气道疾病患者中进行肺活量和第一秒用力呼气量测量时，维达福与伯恩斯坦的校准效果良好。因此，建议它可能适用于评估患者和正常受试者的用力呼气量和肺活量，或用于人群调查工作。它重量轻、便于携带且坚固耐用这一事实也是一个优点。
