Key result
The HUAWEI WATCH D wrist blood pressure monitor met AAMI/ESH/ISO Universal Standard requirements, with mean systolic/diastolic differences of -1.4/-0.2 mmHg compared to reference readings.
Why the study?
The study evaluated the accuracy of the watch-type automated oscillometric wrist BP monitor HUAWEI WATCH D according to the AAMI/ESH/ISO Universal Standard.
Does the HUAWEI WATCH D wrist blood pressure monitor provide accurate blood pressure measurements compared to reference readings in the general adult Chinese population?
Cross-Sectional (n=85)
Does the HUAWEI WATCH D wrist blood pressure monitor provide accurate blood pressure measurements compared to reference readings in the general adult Chinese population?
Mean Difference: -1.4
The HUAWEI WATCH D wrist blood pressure monitor meets international validation standards for accuracy and can be recommended for self-measurement in the general population.
May support self-monitoring with the HUAWEI WATCH D in Chinese adults; leaves open generalizability to other populations and settings.
OBJECTIVE: The aim of this study was to evaluate the accuracy of the watch-type automated oscillometric wrist blood pressure (BP) monitor HUAWEI WATCH D in the general population according to the Association for the Advancement of Medical Instrumentation/European Society of Hypertension/International Organization for Standardization (AAMI/ESH/ISO) Universal Standard. METHOD: Subjects were recruited to fulfill the age, sex, BP and cuff distributions of the AAMI/ESH/ISO Universal Standard in the general population using the same arm sequential BP measurement method. Two cuffs of the test device were used for wrist circumference of 13-16 cm (medium) and 16-20 cm (large), respectively. RESULTS: One-hundred and nine subjects were recruited and 85 were analyzed. For validation criterion 1, the mean ± SD of the differences between the test device and reference BP readings was -1.4 ± 6.47/-0.2 ± 5.85 mmHg (systolic/diastolic). For criterion 2, the SD of the average BP differences between the test device and reference BP per subject was 5.66/5.48 mmHg (systolic/diastolic). CONCLUSION: The HUAWEI WATCH D watch-type wrist BP monitor fulfilled all the requirements of the AAMI/ESH/ISO Universal Standard in the general population and can be recommended for self-measurement.

Zhang et al. (2022) conducted a cross-sectional in General population (n=85). HUAWEI WATCH D oscillometric wrist blood pressure monitor vs. Reference BP readings was evaluated on Mean difference between test device and reference BP readings (systolic/diastolic) (Mean difference -1.4/-0.2 mmHg). The HUAWEI WATCH D wrist blood pressure monitor met AAMI/ESH/ISO Universal Standard requirements, with mean systolic/diastolic differences of -1.4/-0.2 mmHg compared to reference readings.
