Oscillometric blood pressure measurement using a wide-range cuff from 22 to 41 cm of arm circumference: validation of the Hingmed V03D upper arm blood pressure monitor in a general population

The aim of the study was to determine the accuracy of the Hingmed V03D oscillometric 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. The Hingmed V03D is provided with a wide-range cuff for arm circumferences ranging from 22 to 41 cm. The device was tested in 85 subjects from the general population. The mean age of the participants was 51.7 years (range: 17–71 years). The mean device-observer difference was −1.2 ± 4.0 mmHg for SBP and −2.0 ± 3.7 mmHg for DBP, in agreement with criterion 1 of the protocol standard requirements (≤5 ± 8 mmHg). Criterion 2 of the ISO 81060-2:2018/Amd1:2020/Amd2:2024 protocol was also satisfied. The SD of SBP and DBP were 2.6 and 2.9 mmHg, respectively, well below the maximum values required by the protocol (6.84 and 6.65 mmHg for SBP and DBP, respectively). The measurement errors were unrelated to arm size. These results indicate that the Hingmed V03D is a reliable BP monitor because it satisfied the requirements of the ISO 81060-2:2018/Amd1:2020/Amd2:2024 protocol for the general population. This device showed that a single wide-range cuff can provide accurate measurements in standard as well as large arms with circumferences ranging from 22 to 41 cm.
