Reliability of oscillometric blood pressure measurement using a wide-range cuff from 22 to 41 cm of arm circumference: validation of the Hingmed Q06B upper arm blood pressure monitor for blood pressure measurement at home evaluated in a general population according to the International Organization for Standardization 81060-2:2018 protocol

To determine the accuracy of the Hingmed Q06B monitor for upper arm blood pressure (BP) measurement according to the new International Organization for Standardization (ISO) 81060-2:2018/Amd1:2020/Amd2:2024 protocol (‘Universal Protocol’). The Q06B device, an oscillometric fully automatic BP monitor for BP measurement at home, has a single wide-range cuff for arm circumferences ranging from 22 to 41 cm. The device was tested in 85 subjects from the general population with a mean age of 53.6 ± 11.7 years. The mean device–observer difference was in agreement with criterion one of the protocol standard requirements (≤5 ± 8 mmHg), being −0.7 ± 3.7 mmHg for systolic BP and −1.6 ± 3.6 mmHg for diastolic BP. The measurement errors had a similar magnitude across the entire range of arm sizes. Criterion two of the ISO 81060-2:2018/Amd1:2020/Amd2:2024 protocol is satisfied. The SD of systolic and diastolic BPs were 2.1 and 2.8 mmHg, respectively, well below the maximum values required by the protocol (6.90 and 6.76 mmHg for systolic and diastolic BPs, respectively). These data show that the Hingmed BP monitor Q06B satisfied the requirements of the ISO 81060-2:2018/Amd1:2020/Amd2:2024 protocol for the general population, demonstrating that a single wide-range cuff can provide reliable measurements across a wide range of arm circumferences.
