最大吸气流速—容量曲线(Maximal inspiratory flow—Volume curve MIFV)正常值国内虽有报道,但测定例数较少,为了解我国健康人的正常值及与性别,年龄等因素对MIFV各常数的影响,我们应用上海产的流速容量记录仪,对240例健康人进行了测定,其结果如下: 对象与方法一、检查对象健康人受检查者系本院及医学院的医务人员,学生、干部及各单位健康体查者。健康人的标准;1.无呼吸系统及心血管疾病史;2.体检心,肺及血压均正常;3.X线透视或胸部拍片正常;4.心电图检查无异常发现者。本组共240人,男性120人,女性120人,年龄20～29岁,30～39岁,40～49岁,50～59岁,分四组,每组男女各30例,每个年龄组为60例,平均年龄男性为38.6岁,女性为39.3岁。二、仪器和测量方法应用上海第五七三厂生产的LR—80型流速容
Although there are reports of normal values of normal inspiratory flow-volume curve (MIFV) in China, the number of test cases is relatively small. In order to understand the normal values of normal inspiratory flow-volume curve (MVDV) We used the Shanghai-made flow rate capacity recorder to measure 240 healthy people. The results were as follows: Subjects and Methods 1. Subjects for examination The healthy subjects under examination were medical staff, students and cadres in this hospital and medical school And all units of health investigation. Healthy people’s standards; 1. No history of respiratory system and cardiovascular disease; 2. Physical examination heart, lungs and blood pressure were normal; 3. X-ray or chest film was normal; 4. Electrocardiogram no abnormal findings. This group of 240 people, 120 males and 120 females, aged 20 to 29 years old, 30 to 39 years old, 40 to 49 years old, 50 to 59 years old, divided into four groups of 30 men and women in each group, each age group 60 cases, the average age of 38.6 years for men and 39.3 years for women. Second, the application of instruments and measurement methods Shanghai No. 537 factory production LR-80-type flow rate capacity
