Use of an automated electronic sphygmomanometer will allow us to minimize the errors inherent in mercury sphygmomanometry. We conducted this validation according to the 1990 protocol of the British Hypertensive Society. We recruited 87 subjects from the antenatal population of Kandang Kerbau Hospital and took three sequential readings using simultaneously both manual and electronic sphygmomanometry. A total of 261 readings from either method were thus collected and the results analyzed to compare the accuracy of electronically read blood pressure with that assessed manually. We found that 89.9% of the electronically read pressures differed from the manually read pressures by 5 mm Hg or less and 98.9% of the electronic readings differed from manual readings by 10 mm Hg or less; only 0.4% of readings had a difference of more than 15 mm Hg. The accuracy of the device was not affected either by the blood pressure or the arm circumference.

使用自动电子血压计将使我们能够最大程度地减少汞血压计固有的误差。我们根据1990年英国高血压学会的协议进行了验证。我们从Kandang Kerbau医院的产前人群中招募了87名受试者,并同时使用手动和电子血压计进行了三个顺序的读数。因此,从这两种方法中总共收集了261个读数,并对结果进行了分析,以比较电子读取血压与手动评估血压的准确性。我们发现89.9%的电子读数压力与手动读数压力相差5毫米汞柱或更少,而98.9%的电子读数压力与手动读数相差10 mm Hg或更少。只有0.4%的读数相差超过15毫米汞柱。该设备的精度不受血压或手臂圆周的影响。
