A quality control of spirographic examinations in a health centre was carried out by repeating, after a fortnight's interval, measures of vital capacity (CV) and FEV1 (VEMS) in 629 subject of both sexes, aged 18 to 62. Water spirometers were used and their cylinders were regularly calibrated. The first series of spirographic measurements were made during a routine health check (which included other examinations) by 7 technicians who usually do the work, while the second series of measurements was made of fortnight later by the most experienced three. The overall mean values show a significant difference for vital capacity between the first and second measurement; this difference was so for young male subjects (less than 30 years). The scatter was greater for subjects over 50 years of age. The varied results observed for the same subjects obtained by two different technicians, or the same technician, underlines the fact that the scatter of the results depends largely on the technician even though spirographic tests are classically considered easy to perform.
在一家健康中心，对肺功能检查进行了质量控制。对629名年龄在18至62岁的男女受试者，间隔两周重复测量肺活量（CV）和第一秒用力呼气量（FEV1，即VEMS）。使用了水肺量计，其圆筒定期校准。第一轮肺功能测量由7名通常从事此项工作的技术人员在常规健康检查（包括其他检查）期间进行，而第二轮测量在两周后由最有经验的三名技术人员进行。总体平均值显示，第一次和第二次测量的肺活量存在显著差异；年轻男性受试者（不到30岁）也是如此。50岁以上受试者的离散度更大。由两名不同技术人员或同一名技术人员对同一受试者进行测量时得到的不同结果，突出了这样一个事实：尽管肺功能测试通常被认为易于操作，但结果的离散度在很大程度上取决于技术人员。
