A wrist-cuff automated oscillometric device is portable and useful for self-monitoring of blood pressure (BP) at home and outdoors when an upper arm device is not available. Although the height of the forearm in wrist BP measurement is acknowledged to be the major cause of measurement error, it remains unclear whether exercise affects subsequent wrist BP measurement.
Ninety-seven healthy college students (median age of 20 years with an age range of 19 to 36 years, 70.1% males) participated in this study. Care was taken to keep the position of the wrist at a level near the upper arm level in BP measurement. At rest, BP measured by a wrist-cuff oscillometric device (Omron HEM-6183) was generally acceptable when it was compared with BP measured by an upper arm oscillometric device (Omron HEM-7130-HP) and with BP measured by the auscultatory method using a mercury sphygmomanometer. However, the ratio of systolic BP measured by oscillometric devices just after a two-step exercise test to that before exercise on the wrist (1.22 ± 0.14) was significantly lower than the ratio on the upper arm (1.27 ± 0.14), and the difference was significantly correlated with exercise-induced increase in pulse rate (Spearman's ρ = 0.23), suggesting a possible role of autonomic nerve activity in the blunted response to exercise-induced BP elevation in wrist BP measurement.
The results indicate that the blunted response to exercise-induced BP elevation should be considered in wrist BP measurement when using a wrist-cuff oscillometric device.
腕带式自动示波法血压计体积小巧，便于携带，在无法使用上臂式血压计的情况下，可用于家庭或户外的血压自我监测。尽管前臂在腕部血压测量中的高度是导致测量误差的主要原因，但目前仍不清楚运动是否会影响后续的腕部血压测量。
本研究纳入了 97 名健康的大学生（中位年龄 20 岁，年龄范围为 19 岁至 36 岁，70.1%为男性）。在测量血压时，我们会特别注意将腕部位置保持在接近上臂水平的高度。在休息状态下，与上臂示波法（欧姆龙 HEM-7130-HP）和听诊法（使用水银血压计）相比，腕带式示波法（欧姆龙 HEM-6183）测量的血压通常是可接受的。然而，在刚刚进行完两步运动试验后，与运动前相比，腕部（1.22±0.14）的收缩压与示波法测量值的比值明显低于上臂（1.27±0.14），且这种差异与运动引起的脉搏率增加呈显著相关（Spearman's ρ=0.23），这表明自主神经活动可能在腕部血压测量中对运动引起的血压升高反应减弱起到了一定作用。
这些结果表明，在使用腕带式示波法血压计时，应考虑到运动引起的血压升高反应减弱的问题。
