The validation was performed in 33 individuals. Their mean age was 59.6±12.9 years, systolic blood pressure (BP) was 144.3±21.5 mmHg (range: 96–184 mmHg), diastolic BP was 86.8±18.5 mmHg (range: 48–124 mmHg), and arm circumference was 30.2±4.3 cm (range: 23–39 cm). Four sequential readings were taken by observers 1 and 2 using a double-headed stethoscope and a mercury sphygmomanometer, whereas three BP readings were taken by the supervisor using the test instrument. The differences between the readings provided by the device and the mean observer measurements were calculated. Therefore, each device measurement was compared with the previous and the next mean observer measurement. The validation results fulfilled all the 2010 European Society of Hypertension revision Protocol criteria for the general population and passed all validation grades. On average, the device overestimated systolic BP by 1.7±2.4 mmHg and diastolic BP by 1.7±2.5 mmHg. These data show that the UM-211 device coupled to several cuffs for different ranges of arm circumference met the requirements for validation according to the International Protocol and can be recommended for clinical use in the adult population. However, these results mainly apply to the use of the 22–32 and the 31–45 cm cuffs. Copyright © 2017 Wolters Kluwer Health, Inc. All rights reserved.
