To determine the accuracy of the large-extra large-sized (L-XL) cuff (32-52 cm) coupled to a Microlife WatchBP Office ABI blood pressure measuring device tested according to the requirements of the International Protocol of the European Society of Hypertension. The L-XL cuff tested in this study is designed to provide accurate blood pressure measurements in patients with large arms (arm circumference≥32 cm) over a wide range of arm circumferences using a single 145±1×320±1 mm bladder. The evaluation was made in 33 patients with a mean±standard deviation age of 53±17 years (range: 30-96 years). Their systolic blood pressure (SBP) was 142±21 mmHg (range: 110-180 mmHg), diastolic blood pressure (DBP) was 87±14 mmHg (range: 62-106 mmHg) and arm circumference was 36±5 cm (range: 32-50 cm). Blood pressure measurements were made in the sitting position. The L-XL cuff coupled to the WatchBP Office ABI passed all three phases of the European Society of Hypertension protocol for SBP and DBP. Mean blood pressure differences between device and observer were -1.3±5.1 mmHg for SBP and -1.8±5.8 mmHg for DBP. Similar device-observer differences were observed in patients divided into two subgroups according to whether their arm circumference was above or below the median in the group. These results indicate that the L-XL cuff coupled to the WatchBP Office ABI monitor provides accurate blood pressure readings in patients with large arms over a wide range of arm circumferences.
为了确定根据欧洲高血压学会国际协议要求进行测试的，与迈克大夫WatchBP Office ABI血压测量设备配套的大 - 超大号（L - XL）袖带（32 - 52厘米）的准确性。本研究中测试的L - XL袖带旨在通过单个145±1×320±1毫米的气囊，为上臂较粗（臂围≥32厘米）的患者在广泛的臂围范围内提供准确的血压测量值。对33名患者进行了评估，其平均年龄±标准差为53±17岁（范围：30 - 96岁）。他们的收缩压（SBP）为142±21毫米汞柱（范围：110 - 180毫米汞柱），舒张压（DBP）为87±14毫米汞柱（范围：62 - 106毫米汞柱），臂围为36±5厘米（范围：32 - 50厘米）。血压测量在坐姿下进行。与WatchBP Office ABI配套的L - XL袖带通过了欧洲高血压学会协议中关于收缩压和舒张压的所有三个阶段测试。设备与观察者之间的平均血压差异，收缩压为 -1.3±5.1毫米汞柱，舒张压为 -1.8±5.8毫米汞柱。根据臂围在组中是高于还是低于中位数，将患者分为两个亚组，在这两个亚组中观察到了类似的设备 - 观察者差异。这些结果表明，与WatchBP Office ABI监测仪配套的L - XL袖带，能为上臂较粗且臂围范围广泛的患者提供准确的血压读数。
