Abstract：
UNASSIGNED: Some brachial cuffs for oscillometric blood pressure (BP) measurement are claimed to cover a wide range of upper-arm circumferences; however, their validation is rarely conducted. Our aim was to compare oscillometric BP measurements obtained with a universal cuff with those obtained with an appropriately sized cuff.
UNASSIGNED: We utilised the Microlife B6 Connect monitor, conducting oscillometric BP measurements in a random sequence with both a universal cuff (recommended for arm circumferences from 22 to 42 cm) and an appropriately sized cuff (medium for circumference 22-32 cm and large for 32-42 cm). We included 91 individuals with an arm circumference of 22-32 cm and 64 individuals with an arm circumference of 32-42 cm.
UNASSIGNED: For arm circumferences > 32 cm, systolic and diastolic BP measured with the universal cuff was higher than that measured with the large cuff (systolic 6.4 mmHg, 95% confidence interval [CI]). 3.9-8.8, diastolic 2.4 mmHg, 95%CI, 1.2-3.7, p < 0.001 for both). Overestimation of BP with the universal cuff was statistically significant after correcting for the sequence of measurements. No statistical difference was found between the universal cuff and medium cuff for circumferences in the 22-32 cm range. The bladder size in the universal cuff matched the dimensions of the medium-sized cuff; however, the cuff was larger.
UNASSIGNED: Overestimation of BP measured with a universal cuff in persons with large arm circumferences is clinically important. It poses the risk of unnecessary initiation or intensification of antihypertensive medication in persons using the universal cuff.
What is the context?Clinical guidelines recommend individualisation of the size of the cuff used for blood pressure measurement according to the circumference of the upper arm.Many blood pressure monitors are sold with a single “universal” cuff claimed to cover a wide range of upper arm sizes.We compared blood pressure obtained with the Microlife B6 Connect monitor and a “universal” cuff with the results obtained with individual sized cuffs (medium size for arm circumference between 22 and 32 cm and large size for arm circumference between 32 and 42 cm).What is new?In persons with large upper arm circumference is the systolic blood pressure 6.4 mmHg higher and the diastolic blood pressure 2.4 mmHg higher with the universal cuff than with the individual-sized large cuff.What is the impact?The universal cuff overestimates blood pressure in persons with large arm circumference.

摘要：
■据称，用于示波血压（BP）测量的某些肱袖带覆盖了很宽的上臂圆周范围；但是，他们的验证很少进行。我们的目的是将使用通用袖带获得的示波BP测量值与使用适当尺寸袖带获得的示波BP测量值进行比较。
■我们使用了MicrolifeB6Connect监视器，使用通用袖带（建议用于22至42cm的手臂周长）和适当尺寸的袖带（中等周长为22-32cm，大周长为32-42cm）进行随机序列的示波BP测量。我们包括91个手臂周长为22-32厘米的个体和64个手臂周长为32-42厘米的个体。
■对于手臂周长>32厘米，用通用袖带测量的收缩压和舒张压血压高于用大袖带测量的收缩压和舒张压血压(收缩压6.4mmHg，95%置信区间[CI])。3.9-8.8，舒张压2.4mmHg，95CI，1.2-3.7，两者p<0.001)。校正测量顺序后，使用通用袖带对BP的高估具有统计学意义。对于22-32cm范围内的圆周，通用袖带和中等袖带之间没有发现统计学差异。通用袖带中的膀胱尺寸与中型袖带的尺寸相匹配；但是，袖口更大。
■在手臂周大的人群中，用通用袖带测量的BP的高估在临床上很重要。在使用通用袖带的人中存在不必要地开始或加强抗高血压药物的风险。
背景是什么？临床指南建议根据上臂的周长个性化用于血压测量的袖带的尺寸。许多血压监测仪都带有一个“通用”袖带，声称可以覆盖各种上臂尺寸。我们将使用MicrolifeB6Connect监护仪和“通用”袖带获得的血压与使用单个尺寸袖带获得的结果进行了比较（中等尺寸的手臂周长在22至32厘米之间，而大尺寸的手臂周长在32至42厘米之间）。有什么新消息？在上臂周长较大的人中，通用袖带的收缩压高6.4mmHg，舒张压高2.4mmHg。有什么影响？通用袖带高估了手臂围较大的人的血压。
