| 中文摘要: |
| 人体在静息状态下的脉图参数,呈现与呼吸时相有关和无关的两种波动,致使两次随机测定的脉图参数之间产生差别。这种由抽样引起的最大可能误差与每次检测抽样的连续脉波数之间呈类似双曲线的关系,抽样脉波数在10个以下时,误差很大,超过20个以后,误差渐接近于最小值。 |
| 英文摘要: |
| After determining synchronously the right radial sphygmogram(at"Guan"(关)position of the wrist), electrocardiogram(standard limb Ⅱ lead ),and curve of respiratory movements in healthy persons proved in health checkup,who were in a supine position at rest,it was found that their sphygmogram parameters presented two types of fluctuations:one was related to respiratory phases and the other was irrelevant to that. Owing to the presence of these fluctuations,there existed variations between the values of sphygmogram parameters in the two random examinations of the same subject.The relation between the maximal probable error from the sampling and the number of consecutive pulse waves determined in each examination was similar to a hyperbolic curve.When the number of consecutive pulses taken in each test was below 10,the maximal probable error between the two random examinations might be very large;but if the number was over 20,the curve would gradually become parallel to abscissa,i.e.the probale error reached minimum. Therefore,it was suggested that if a representative and precise.value of each sphygmogram parameter was expected,one had to examine morn than 20 coasecutive pulses in each test and took the average of the measured values. |
