The performance of five units of the A&D UA-767 NIBP monitor and five units of the Welch Allyn Spot Vital Signs noninvasive blood pressure monitor was evaluated with the Biotek BP Pump blood pressure simulator under a variety of conditions. Using the simulator to provide a normal blood pressure waveform at 80 bpm over a range of pressures, it was found that the mean bias for the combined results from the A&D monitors was 1.9+/-2.8 mmHg and from the Welch Allyn monitors was 0.7+/-2.4 mmHg. No individual measurement showed a bias greater than 10 mmHg. A bias of greater than 5 mmHg was present in 28 out of 150 measurements for the A&D monitor and 10 out of 150 measurements for the Welch Allyn monitor. These results are comparable with ratings achieved by the instruments when tested previously according to the British Hypertension Society protocol, but testing with a simulator allowed assessment of aspects of performance which were not included in the British Hypertension Society protocol.
在各种条件下，使用百泰克血压泵血压模拟器对五台爱安德UA - 767无创血压监测仪和五台伟伦SureSight手持式自动电子血压计进行了性能评估。利用模拟器在一系列压力下以80次/分钟的频率提供正常血压波形，结果发现，爱安德监测仪综合结果的平均偏差为1.9±2.8 mmHg，伟伦监测仪的平均偏差为0.7±2.4 mmHg。没有任何一次单独测量的偏差超过10 mmHg。爱安德监测仪的150次测量中有28次偏差大于5 mmHg，伟伦监测仪的150次测量中有10次偏差大于5 mmHg。这些结果与这些仪器先前按照英国高血压学会方案进行测试时所获得的评级相当，但使用模拟器进行测试能够评估英国高血压学会方案未涵盖的性能方面。
