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

血壓是波動(dòng)性和變異性較大的生命指標(biāo)，因此偶然一次測(cè)得的血壓不能反映全天的血壓變化趨勢(shì)，需要多次反復(fù)檢測(cè)才能夠?qū)σ粋€(gè)患者的血壓進(jìn)行準(zhǔn)確、可靠的評(píng)估。（剩余2439字）
