The Omron HEM-7380T automated blood pressure monitor meets ISO accuracy standards and is considered sufficiently accurate for blood pressure measurements in the general population.
OBJECTIVE: This study aimed to validate the accuracy of Omron HEM-7380T (HCR-7728T), an automated deflationary oscillometric upper-arm blood pressure (BP) monitor, according to the international organization for standardization (ISO) 81060-2 : 2018 + Amd1 : 2020 and Amd2 : 2024 protocols (ISO standards). METHODS: Accuracy was assessed by alternately measuring systolic BP (SBP) and diastolic BP (DBP) in the same arm using the test device and a mercury sphygmomanometer. All participants met the inclusion criteria outlined in the protocol. RESULTS: A total of 85 patients were included (43 males and 42 females), with a mean age of 63.9 ± 10.3 years and a mean arm circumference of 26.7 ± 5.4 cm. Regarding Criterion 1, the mean ± SD of the differences between the test device and reference BP was 0.1 ± 6.85 mmHg for SBP and 0.9 ± 5.41 mmHg for DBP, fulfilling the ISO requirement of less than or equal to 5 ± less than or equal to 8 mmHg. For Criterion 2, the SD values were 0.1 ± 5.69 mmHg for SBP and 0.9 ± 4.95 mmHg for DBP, satisfying the required thresholds of less than or equal to 6.95and less than or equal to 6.88, respectively. The results indicated that this device conforms to the ISO standards. CONCLUSION: Omron HEM-7380T fulfilled criteria 1 and 2 of the protocol. Therefore, the device is considered sufficiently accurate for BP measurements in the general population.

Takahashi et al. (2026) conducted a cross-sectional in Blood pressure measurement (n=85). Omron HEM-7380T (HCR-7728T) vs. Mercury sphygmomanometer was evaluated on Accuracy of systolic and diastolic BP measurements according to ISO standards. The Omron HEM-7380T blood pressure monitor fulfilled ISO accuracy criteria compared to a mercury sphygmomanometer, with mean differences of 0.1 ± 6.85 mmHg for SBP and 0.9 ± 5.41 mmHg for DBP.
