Abstract： Electronic blood pressure monitors have become one of the most common devices for measuring human blood pressure， the evaluation of uncertainty is an important indicator for determining the accuracy of measurement values. This article introduces the evaluation and expression method of uncertainty in the measurement results of static pressure indication error of a non-invasive automatic measurement blood pressure monitor based on the principle of oscilloscope method.

Keywords： non invasive automatic blood pressure measuring device； uncertainty evaluation； static pressure indication error

0引言

血压是波动性和变异性较大的生命指标，因此偶然一次测得的血压不能反映全天的血压变化趋势，需要多次反复检测才能够对一个患者的血压进行准确、可靠的评估。（剩余2439字）
