Validation of the InBody BPBIO250 oscillometric blood pressure monitor for professional office use in general population according to the Association for the Advancement of Medical Instrumentation/European Society of Hypertension/International Organization for Standardization Universal Standard.

Objective The aim of this study was to evaluate the accuracy of the InBody BPBIO250 oscillometric upper-arm professional office blood pressure (BP) monitor in 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 (ISO 81060-2:2018). Methods Subjects were recruited to fulfil the age, gender, BP, and cuff distribution criteria of the AAMI/ESH/ISO Universal Standard in general population using the same arm sequential BP measurement method. Two cuffs of the test device were used for arm circumference 22-32 (medium) and 32-42 cm (large). Results Ninety-seven subjects were recruited and 88 were analyzed. For validation criterion 1, the mean +/- SD of the differences between the test device and reference BP readings was 1.9 +/- 5.9/0.9 +/- 4.9 mmHg (systolic/diastolic). For criterion 2, the SD of the averaged BP differences between the test device and reference BP per subject was 4.78/4.31 mmHg (systolic/diastolic). Conclusion The InBody BPBIO250 professional oscillometric device for office BP measurement fulfilled all the requirements of the AAMI/ESH/ISO Universal Standard (ISO 81060-2:2018) in general population and can be recommended for clinical use.
