目的 评价OMRON HEM-770A型智能电子血压计测量血压的准确性.方法 根据中华人民共和国医药行业标准 YY 0670-2008<无创自动测量血压计>关于电子血压计准确性评价的要求,利用标准汞柱式血压计(听诊法)与受试电子血压计对85名受试者同臂同步测量血压,对比评价该电子血压计的准确性.结果 OMRON HEM-770A型电子血压计的测量结果高出标准听诊法1.9 mm Hg/1.5 mm Hg(收缩压/舒张压),其偏差小于5 mm Hg的上限;偏差的标准差为4.2 mm Hg/3.6 mm Hg(收缩压/舒张压),小于8 mm Hg的上限;收缩压和舒张压偏差在10 mm Hg以内的测量次数分别占到96.9%和98.4%,高于85%的最低要求.结论 OMRON HEM-770A型智能电子血压计具有良好的准确性,收缩压和舒张压均达到了国内行业标准规定的要求.%Objective To evaluate the accuracy of the electronic sphygmomanometer OMRON HEM - 770A. Methods A comparative study was carried out according to the accuracy evaluation requirements on electronic sphygmomanometer in the Medical Industry Standards YY 0670 - 2008 , or Non - Invasive Automated Blood Pressure Measurement. The arm blood pressures of 85 participants were measured simultaneously with both the standard mercury sphygmomanometer and the electronic device. Results The readings of OMRON HEM -770A were higher than those of reference mercury sphygmomanometer by 1. 9 mm Hg/1. 5 mm Hg ( systolic/diastolic ) in average, less than the maximum offset of 5 mm Hg set by the Chinese standards. The standard deviation of the offsets was 4. 2 mm Hg/3. 6 mm Hg, less than the maximum offset of 8 mm Hg. Compared with the mercury reference. electronic readings≤lOmmHg offset accounted for 96. 9％ and 98. 4％ for systolic and diastolic blood pressure ,respectively, meeting the minimum 85％ standard. Conclusion The electronic sphygmomanometer OMRON HEM - 770A shows good accuracy and meet the domestic industry - standard requirements for both systolic and diastolic blood pressure.
