Oscillometric blood pressure devices tend to overestimate systolic blood pressure and underestimate diastolic blood pressure compared with sphygmomanometers. Recent studies indicate that discrepancies in performance between these devices may differ between healthy and diabetic subjects. Arterial stiffness in diabetics could be the underlying factor explaining these differences. We studied differences between a Dinamap oscillometric blood pressure monitor and a random-zero sphygmomanometer in relation to arterial stiffness in 1808 healthy elderly subjects. The study was conducted within the Rotterdam Study, a population-based cohort study of subjects aged 55 years and older. Systolic and diastolic blood pressure differences between a Dinamap and a random-zero sphygmomanometer were related to arterial stiffness, as measured by carotid-femoral pulse wave velocity. Increased arterial stiffness was associated with higher systolic and diastolic blood pressure readings by the Dinamap compared with the random-zero sphygmomanometer, independent of age, gender, and average mean blood pressure level of both devices. The beta-coefficient (95% CI) was 0.25 (0.00 to 0.50) mm Hg/(m/s) for the systolic blood pressure difference and 0.35 (0.20 to 0.50) mm Hg/(m/s) for the diastolic blood pressure difference. The results indicate that a Dinamap oscillometric blood pressure device, in comparison to a random-zero sphygmomanometer, overestimates systolic and diastolic blood pressure readings in subjects with stiff arteries.
与血压计相比，示波法血压测量设备往往会高估收缩压并低估舒张压。最近的研究表明，这些设备之间的性能差异在健康受试者和糖尿病受试者中可能有所不同。糖尿病患者的动脉僵硬度可能是解释这些差异的潜在因素。我们在1808名健康老年受试者中研究了Dinamap示波法血压监测仪与随机零点血压计在动脉僵硬度方面的差异。该研究是在鹿特丹研究中进行的，这是一项基于人群的队列研究，研究对象为55岁及以上的受试者。Dinamap血压计与随机零点血压计之间的收缩压和舒张压差异与通过颈股脉搏波速度测量的动脉僵硬度相关。与随机零点血压计相比，动脉僵硬度增加与Dinamap测量的更高收缩压和舒张压读数相关，且不受年龄、性别以及两种设备的平均血压水平影响。收缩压差异的β系数（95%置信区间）为0.25（0.00至0.50）mmHg/（m/s），舒张压差异的β系数为0.35（0.20至0.50）mmHg/（m/s）。结果表明，与随机零点血压计相比，Dinamap示波法血压测量设备会高估动脉僵硬受试者的收缩压和舒张压读数。
