无创血压袖带缠绕方向和位置对血压测量的影响

目的探讨无创血压袖带缠绕方向和位置对血压测量的影响。方法将96例危重患者进行自身对照研究，将传感器置于肱动脉上和上臂外侧，每次间隔5分钟，进行正向和反向测量血压，记录测量数值。结果不同组间收缩压、舒张压和平均乐总体比较差异无统计学意义（P〉0．05），进一步行各组间多重比较差异无统计学意义（P〉0．05）。结论心电监护仪无创血压测量时，袖带的缠绕方向和位置不影响血压值的准确性。

Effect of winding direction and position of non-invasive blood pressure cuff on blood pressure measurement

Objective To explore the effects of the winding direction and position of noninvasive blood pressure cuff on blood pressure measurement. Methods A self-control study was conducted in 96 critically ill patients. We placed the sensor of a sphygmomanometer on brachial artery and the lateral side of the upper arm, then measured blood pressure every 5 minutes in forward and reverse directions, and then documented the readings. Results The systolic pressure, diastolic pressure, and mean blood pressure did not differ significantly among different （ P〉 0.05 ）;, multiple comparisons did not show significant differences （ P 〉 0.05 ）. Conclusions The winding direction and location of noninvasive blood pressure cuff have no effects on the accuracy of blood measurement by using a ECG monitor.
