摘要
目的:研究袖带内幅与臂围的比率引起血压值误差的规律性。方法:应用不同内幅的袖带测定血压,以袖带内幅与臂围的比率为40％所测得的血压作为基准,与之相比较,求出臂围的20％～90％的袖带幅度所测得的血压误差的平均值,并找出其规律性。结果:臂围30％幅度的袖带测定的收缩压误差值为4.7 mmHg,舒张压误差值为3.5 mmHg;臂围50％幅度的袖带测定的收缩压误差值为-4.1 mmHg,舒张压误差值为-1.4 mmHg;臂围60％幅度的袖带测定的收缩压误差值为-8.9 mmHg,舒张压误差值为-4.9 mmHg。结论:袖带内幅与臂围的比率和血压误差值之间存在线性关系,回归方程:Y=28.32-0.69 x(收缩压),Y=19.12-0.48 x(舒张压)。
objective:To study the regularity on error of blood pressure Caused ny the proportion of culf-width /arm culf.
Methods: Take blood pressure with different size of culf, and set the results from 40% proportion of culf- width and arm - girth as the standand, others compared with it,then calculated the average error from 20% - 90% proportion of them and find out the regularity. Results:The error of systolic pressure was 4.7 mmHg and diastolic pressure was 3.5 mmHg in the 30% group,and - 4. 1 mmHg and
-1.4 mmHg in the 50% group. Conclusion: There' s linearity relation between the proportion of culf - width / arm - girth and error of
blood pressure. The regression equation is: Y = 28. 32 - 0.69 X (systolic), Y = 19.12 - 0.48 X (diastolic)
