本文通过对随机零点血压计的原理和使用做一简要介绍,提示随机零点血压计在降低测量者的目测 误差及对数字偏爱所致的误差要优于标准水银血压计,尤其适用于高血压的人群流行病学研究,特别是分析大量 资料时可以减少误差。
In this paper, the principle and use of a random zero sphygmomanometer are briefly introduced. It is suggested that the random zero sphygmomanometer is superior to the standard mercury sphygmomanometer in reducing the visual error of the measuring person and the error caused by the digital preference, especially for hypertension Epidemiological studies of populations, especially when analyzing large volumes of data, can reduce errors.
