袖口/手臂周长比例会影响血压测量的准确性. 80%-84%的比率产生了最小的静缩血压误差,而85%-89%的静缩血压误差最小化.
科学领域:
- 心血管研究的心血管研究.
- 医疗器械的准确性 医疗器械的准确性
- 临床测量验证临床测量验证
背景情况:
- 准确的血压 (BP) 测量对于心血管健康管理至关重要.
- 袖口/手臂 (C/A) 周长比率是影响血压测量准确性的关键因素.
- 目前的指南建议C/A比率大于80%,但最佳范围需要进一步调查.
研究的目的:
- 评估不同C/A周长比 (80%-100%) 对袖血压 (BP) 测量的准确性的影响.
- 将袖口血压测量与参考臂内血压 (IABP) 进行比较,以确定缩和腹缩血压的最佳C/A比率.
主要方法:
- 一项研究涉及253名患者 (平均年龄62.42±9.70岁) 进行冠状动脉血管造影后.
- 内血压 (IABP) 通过动脉内导管连续记录.
- 使用三种不同的袖口的血压计测量袖口BP,以达到80%-84%,85%-89%和90%-100%的C/A比率.
主要成果:
- 缩血压 (SBP) 的最小百分比偏差度 (DD) 观察到的C/A比率为80%-84% (3.06%).
- 腹筋血压 (DBP) 的最低DD被发现在C/A比率为85%-89% (2.47%).
- 这些发现适用于不同性别以及患有或没有冠心病的参与者.
结论:
- 即使在推的>80%范围内,特定的C/A比率也可以优化BP测量的准确性.
- 80%-84%的C/A比率对于SBP测量是最准确的.
- 85%-89%的C/A比率为DBP测量提供了最高的精度.

Special considerations while measuring blood pressure
Monitoring Both Arms:
Monitoring BP in both arms during the initial assessment is advisable, as the systolic value may differ by five to ten mm Hg between arms. For subsequent BP assessments, use the arm with the higher reading.
