臂式电子血压计与水银血压计测量血压差异性研究

Study on blood pressure measurement difference between arm electronic sphygmomanometer and mercury sphygmomanometer

目的 研究臂式电子血压计与水银血压计所测得血压值的差异。方法 随机选择113例住院患者，其中男性57例，女性56例；年龄23 ～ 74岁，平均年龄38.74岁。分别用臂式电子血压计和水银血压计按相同操作规程测量血压，比较两者所测血压值的差异，并对臂式电子血压计的重复性进行分析。结果 臂式电子血压计与水银血压计测得的血压值差异无统计学意义[（14.93 ± 2.40） kPa/（9.33 ± 1.54） kPa vs （14.81 ± 2.24） kPa/（9.20 ± 1.49） kPa；P 〉0.05）]；臂式电子血压计重复性检测，收缩压、舒张压3次测量值两两比较，差异均无统计学意义（P 〉 0.05）。结论 臂式电子血压计与水银血压计测得血压值相当，且臂式电子血压计更安全，具有良好的重复性，操作简单，便于携带，具有良好的应用前景。

Objective To study differences of blood pressure values obtained from arm electronic sphygmomanometer and mercury sphygmomanometer. Methods A total of 113 hospitalized patients were enrolled, included 57 males and 56 females,aged 23- 74 years with mean age of 38.74 years old. All of them were measured blood pressure either by electronic sphygmomanometer or mercury sphygmomanometer in same procedure, the differences of blood pressure values between 2 methods were compared, and the repeatability analysis were carried out on electronic sphygmomanometer measurement. Results There was no significant difference of blood pressure values between arm electronic sphygmomanometer and mercury sphygmomanometer measurement[（14.93 ± 2.40） k Pa/（9.33 ± 1.54） k Pa vs（14.81 ± 2.24） k Pa/（9.20 ± 1.49） k Pa; P 0.05]. For repetitive testing of electronic sphygmomanometer, pairwise comparisons results of 3 measurement values of systolic and diastolic blood pressures had no statistical significance（P〉 0.05）. Conclusion It is demonstrated that the blood pressure value with arm electronic sphygmomanometer and mercury sphygmomanometer are in consistency. Arm electronic sphygmomanometer shows its prospects due to the safety,repeatability, simple operation and easy to carry.
