本文采用日本产Chestgraph Model-STM81型肺功能机对196例各年龄组健康人、60例慢阻肺病人进行了流速-容量曲线的测定。健康人选择标准为无心肺疾病史,无吸烟史,体检心肺正常,胸片及心电图正常,测验时能充分合作者。慢阻肺病人测定时病情属缓解期。测定方法与时间肺活量一样。计算方法是将测得的流速-容量曲线以特种计算尺分别计算出峰值流速(pV)、V75%、V50%、V25%、V15%、肺活量的流速,V50/V25的比值以及峰值相对
In this paper, Japan-made Chestgraph Model-STM81-type lung function machine 196 cases of healthy people of all age groups, 60 patients with COPD were measured flow-capacity curve. Selection criteria for healthy people without heart disease history, no history of smoking, physical and mental health check-ups, normal chest and ECG, the test can fully cooperate. Chronic obstructive pulmonary disease patients when the disease is remission. The measurement method is the same as the time vital capacity. The calculation method is to calculate the peak flow rate (pV), V75%, V50%, V25%, V15%, the flow rate of vital capacity, the ratio of V50 / V25 and the peak relative to the measured flow rate-
