To directly compare the accuracy of the BpTRU (an automated oscillometric blood pressure device) with standard auscultatory mercury sphygmomanometry in a pediatric population.
The BpTRU was connected in parallel with a standard mercury sphygmomanometer. Two observers measured the blood pressures at the same time as it was being measured by the BpTRU. The observers and the BpTRU were all blinded from each other.
For each of the demographic data--subject age, sex and arm sizes--the mean, standard deviation (SD) and range was calculated. The difference between the mean BpTRU and the standard reference measurements (observer average) was calculated with SD and ranges. The percentage of measurements within 5, 10 and 15 mmHg agreement was expressed.
From the 36 subjects recruited aged 3-18 years, 162 pairs of sitting blood pressures were included. The difference between the mean BpTRU readings and the reference standard measurements (as determined by the observers) was 1.45+/-5.67 mmHg for systolic blood pressures, and -3.24+/-7.39 mmHg for diastolic pressure and 0.20+/-2.47 bpm for heart rate.
The BpTRU is of similar accuracy in measuring blood pressure in children as it was in an adult population.
在儿科人群中直接比较BpTRU（一种自动示波血压测量设备）与标准听诊汞柱式血压计的准确性。
将BpTRU与标准汞柱式血压计并联连接。两名观察者在BpTRU测量血压的同时进行测量。观察者和BpTRU相互之间均不知情。
对于每项人口统计学数据——受试者年龄、性别和手臂尺寸——计算均值、标准差（SD）和范围。计算BpTRU均值与标准参考测量值（观察者平均值）之间的差异及标准差和范围。表示出相差5、10和15 mmHg范围内测量值的百分比。
在招募的36名3至18岁受试者中，纳入了162对坐位血压测量值。收缩压方面，BpTRU读数均值与参考标准测量值（由观察者确定）之间的差异为1.45±5.67 mmHg，舒张压方面为-3.24±7.39 mmHg，心率方面为0.20±2.47次/分钟。
BpTRU在测量儿童血压方面的准确性与在成人人群中相似。
