OMRON HEM-1000臂式电子血压计测量血压的准确性

Accuracy of OMRON upper-arm blood pressure monitors HEM-1000

目的比较OMRON HEM-1000型臂式电子血压计间接测量的血压与肱动脉直接测量的血压差异,探讨臂式电子血压计测量的准确性。方法选取吉安市中心人民医院心内科及南昌大学第二附属医院心内科临床需要行冠状动脉造影的患者200例(男110例,女90例),比较臂式电子血压计测得的血压与肱动脉直接测得的血压差异;将两种测量方法测量的血压值行Bland-Altman图示法;同时用英国高血压学会(BHS)仪器设备评级标准对臂式血压计进行准确性评价。结果臂式电子血压与肱动脉压有明显相关性;臂式电子血压计测得的血压与肱动脉直接测量的血压差异无统计学意义[收缩压(132.7±22.2)比(132.4±21.7)mm Hg,P=0.153;舒张压(81.7±13.5)比(81.2±13.8)mm Hg,P=0.104];两种测量方法测量的血压值一致性较好。按BHS评级标准,臂式电子血压计测量的收缩压及舒张压均为A级。结论臂式电子血压计可准确反映血压值。

Objective To investigate the accuracy of OMRON upperarm electronic blood pressure {BP） monitor HEM-1000 by comparing its indirect BP measurement with the direct BP measurement in the brachial artery. Methods Among the 200 patients enrolled in this study for coronary angiography, 110 were males and 90 females. Blood pressure levels were recorded with both OMRON upperarm electronic monitor HEM-1000 and the direct measurement in the brachial artery. Bland-Altman plots were constructed for their comparisons and the accuracy of the upperarm electronic monitor evaluated by the British Hypertension Society （BHS} standard. Results There was a close correlation between the indirect arm and direct bracbial BP readings. No statistically significant difference was observed in both systolic [（132.7±22.2） vs （132.4±21.7）mm Hg, P=0. 153] and diastolic[-（81.7± 13.5） vs （81.2± 13.8 ）mm Hg, P= 0. 104] levels between the indirect arm readings and direct brachial readings. As reflected in Bland-Altman method, there was good consistency between the two readings. According to the BHS standard, OMRON arm electronic blood pressure monitor HEM-1000 was categorized as Grade A for systolic and diastolic BP levels. Conclusion OMRON upperarm electronic BP monitor HEM-1000 can reflect BP values accurately.
