Wrist blood pressure devices are becoming popular for the self-measurement of blood pressure. Despite widespread use of these devices, there is limited published evidence for their accuracy and reliability. In this study, we assessed the accuracy of the Omron 637IT wrist blood pressure device against the mercury sphygmomanometer in adults and obese adults according to the International Protocol criteria.
A hundred and thirty-one participants were studied and classified on the basis of the International Protocol range. Blood pressure measurements at the wrist using the Omron 637IT were compared with the results obtained by two trained observers using a mercury sphygmomanometer. Nine sequential blood pressure measurements were taken. Initially, 33 participants with random arm circumferences were selected for the first validation study. Then, the device was evaluated in adults with arm circumferences equal to or higher than 34 cm. During each validation study, 99 measurements were obtained for comparison from the 33 participants. The first phase was performed on 15 participants, and, if the device passed this phase, 18 more participants were selected.
Mean discrepancies and standard deviations of the sphygmomanometer device were 0.5+/-6.2 mmHg for systolic blood pressure and 0.1+/-3.7 mmHg for diastolic blood pressure in the adult group. The device passed phases 1 and 2 in 33 participants. Mean discrepancies and standard deviations of the sphygmomanometer device were 1.8+/-6.6 mmHg for systolic blood pressure and 1.6+/-4.7 mmHg for diastolic blood pressure in the obese adult group. The device passed phases 1 and 2 in 33 participants in this group.
The Omron 637IT passed according to the International Protocol criteria and can be recommended for use in adults and obese adults.
腕式血压计在自我测量血压方面正变得越来越流行。尽管这些设备被广泛使用，但关于其准确性和可靠性的已发表证据有限。在本研究中，我们根据国际协议标准评估了欧姆龙637IT腕式血压计相对于汞柱式血压计在成年人和肥胖成年人中的准确性。
对131名参与者进行了研究，并根据国际协议范围进行了分类。使用欧姆龙637IT测量手腕血压，并与两名经过培训的观察者使用汞柱式血压计获得的结果进行比较。进行了九次连续的血压测量。最初，选择33名手臂周长随机的参与者进行首次验证研究。然后，在手臂周长等于或大于34厘米的成年人中对该设备进行评估。在每次验证研究期间，从33名参与者中获得99次测量结果进行比较。第一阶段对15名参与者进行，如果设备通过此阶段，则再选择18名参与者。
在成年组中，汞柱式血压计的收缩压平均差异和标准差为0.5±6.2 mmHg，舒张压为0.1±3.7 mmHg。该设备在33名参与者中通过了第1阶段和第2阶段。在肥胖成年组中，汞柱式血压计的收缩压平均差异和标准差为1.8±6.6 mmHg，舒张压为1.6±4.7 mmHg。该设备在该组的33名参与者中通过了第1阶段和第2阶段。
欧姆龙637IT根据国际协议标准通过了测试，可推荐用于成年人和肥胖成年人。
