【medical-news】美国高血压杂志：自动血压监测仪
Dr. Martin G. Myers and colleagues at the University of Toronto in Ontario recorded blood pressures in 250 individuals, using both an automated sphygmomanometer (BpTRU Medical Devices) and a manual mercury sphygmomanometer, in random order.
Subjects rested for five minutes prior to the first measurement. Four consecutive readings 1 minute apart were taken by mercury sphygmomanometer; the first measurement was discarded and the mean of the following three readings was used. With the automated device, six reading were taken at 1 minute intervals, with the first reading discarded and the mean of the other five readings used.
The mean blood pressure with the automated device was 115/71 mm Hg, compared with 118/74 mm Hg with the manual device, the researches report in the March issue of the American Journal of Hypertension.
A systolic blood pressure of 140 mm Hg or higher was recorded in 16 automated readings and in 19 manual readings. A diastolic blood pressure of 90 mm Hg or higher was recorded in nine automated and 14 manual readings.
Statistical analysis showed that automated and manual readings were not significantly different, Dr. Myers and colleagues say.
"Conventional manual BP readings can be replaced by readings taken using a validated, automated BP recorder in population surveys," the investigators conclude. "The slightly lower readings obtained with the BpTRU device may be a more accurate estimate of blood pressure status."
"This information is important and definitely points to the future of office BP management," Dr. George S. Stergiou of Sotiria Hospital and Third University in Athens, Greece, comments in an accompanying editorial.
However, Dr. Stergiou cautions that the lower readings seen with the automated device need further study. It may be related to the device itself or it may indicate "the elimination of the white coat effect," he says.
"Any change in the conventional methodology should be carefully tested and supported by evidence showing clear improvement in the diagnostic ability of the method," Dr. Stergiou writes.

我认领了 NEW YORK (Reuters Health) Apr 29 - Blood pressures obtained with an automated sphygmomanometer are as accurate as measurement with a standard manual mercury device, Canadian researchers report.
纽约（路透社卫生）4月29日 ---加拿大研究者报道，用自动血压计测得的血压和通过标准的手动水银血压计测得的血压是同样准确的。
Dr. Martin G. Myers and colleagues at the University of Toronto in Ontario recorded blood pressures in 250 individuals, using both an automated sphygmomanometer (BpTRU Medical Devices) and a manual mercury sphygmomanometer, in random order.
马丁，迈尔斯博士和在安大略省多伦多的同事们随机用自动血压计和手动水银血压计给250个个体测血压。
Subjects rested for five minutes prior to the first measurement. Four consecutive readings 1 minute apart were taken by mercury sphygmomanometer; the first measurement was discarded and the mean of the following three readings was used. With the automated device, six reading were taken at 1 minute intervals, with the first reading discarded and the mean of the other five readings used.
在第一次测血压之前受试者先休息5分钟。用水银血压计连续测四次每次相隔1分钟；不计第一次测得值，记录下剩下三次测得值得平均数。用自动血压计测量，则连续测6次每次间隔1分钟，第一次测得值不计记录剩下5次所测血压的平均值。
The mean blood pressure with the automated device was 115/71 mm Hg, compared with 118/74 mm Hg with the manual device, the researches report in the March issue of the American Journal of Hypertension.
研究者在3月份出版的美国高血压杂志报道：自动血压计所测血压的平均值为115/71 mmHg，手动测得血压平均值为118/74 mmHg。
A systolic blood pressure of 140 mm Hg or higher was recorded in 16 automated readings and in 19 manual readings. A diastolic blood pressure of 90 mm Hg or higher was recorded in nine automated and 14 manual readings.
16个自动测量值和19个手工中测量值收缩压为140mmHg或大于140mmHg，9个自动测量值和14个手工测量值中舒张压为90mmHg或大于90mmHg。
Statistical analysis showed that automated and manual readings were not significantly different, Dr. Myers and colleagues say.
迈尔斯博士和他的同事们说：统计分析表明自动和手工读数没有显著差异。
"Conventional manual BP readings can be replaced by readings taken using a validated, automated BP recorder in population surveys," the investigators conclude. "The slightly lower readings obtained with the BpTRU device may be a more accurate estimate of blood pressure status."
