It is recommended that the cuff should be wrapped around the upper arm with the midline of the bladder placed over the brachial artery during blood pressure (BP) measurement. However, in practice, the cuff of sphygmomanometers is often incorrectly placed. The authors aimed to assess the effect on the accuracy of BP measurement as to the placement of the cuff bladder by using oscillometric devices. Participants aged 18 years or older were enrolled. The center of the cuff bladder was placed directly over the brachial artery as the standard position (correct position), which was rotated by 90°medially (medial position), 90°laterally (lateral position), and rotated by 180°(contralateral position), respectively. The main outcomes were non‐invasive brachial BP in the four cuff positions, brachial artery pulse wave velocity, ankle‐brachial index, and invasive radial BP. Of 799 participants, 56.4% were men (60.37 ± 12.73 years), and of the 104 intensive care unit participants, 60.57% were men (57.78 ± 15.89 years). There were no significant differences in non‐invasive brachial BP among the four cuff positions (P > .1), and the mean BP differences between incorrect and standard cuff positions were within 1.0 mm Hg. BP of the incorrect positions was positively correlated with standard position (P < .001, r > .88) and showed good consistency. There was no effect on the accuracy of BP measurement as to the location of the midline of the cuff bladder by using oscillometric devices with a conventional cuff.

袖带定位对自动电子血压计测量血压准确性的影响。

建议在测量血压 (BP) 时将袖带缠绕在上臂上，并将膀胱中线置于肱动脉上方。然而，在实践中，血压计的袖带经常被错误地放置。作者旨在评估使用示波装置放置袖带气囊对血压测量准确性的影响。参加者年龄在 18 岁或以上。将袖带气囊中心置于肱动脉正上方作为标准位（正确位），向内旋转90°（内侧位）、横向90°（侧位）、旋转180°（对侧位） ）， 分别。主要结果是四个袖带位置的无创肱动脉血压、肱动脉脉搏波速度、踝肱指数、和侵入性桡动脉血压。在 799 名参与者中，56.4% 是男性（60.37 ± 12.73 岁），在 104 名重症监护病房参与者中，60.57% 是男性（57.78 ± 15.89 岁）。四种袖带位置的无创肱动脉血压无显着差异（P  > .1)，并且不正确和标准袖带位置之间的平均血压差异在 1.0 毫米汞柱以内。错误体位的血压与标准体位呈正相关（P  < .001，r  > .88）并显示出良好的一致性。使用带有传统袖带的示波装置对袖带气囊中线位置的血压测量准确性没有影响。
