Validation of the automated oscillometric upper-arm cuff home blood pressure monitor AVITA BPM82 in a 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.

OBJECTIVE: This study evaluated the accuracy of the automated oscillometric upper-arm cuff device AVITA BPM82 intended for home use in a 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) and its Amendment 1.2020-01.

METHODS: Participants were recruited to fulfill the age, sex, blood pressure (BP), and limb distribution criteria of the AAMI/ESH/ISO Universal Standard and its Amendment 1.2020-01 in a general population using the same arm sequential BP measurement method. Two cuffs of the test device were used for arm circumference 22-33 (medium) and 33-42 cm (large).

RESULTS: One-hundred-one individuals were recruited and 85 were analyzed [mean age 57.3 ± 15.1 (SD) years, 46 men, arm circumference 32 ± 5.1 cm, range 22.3-42 cm]. For validation Criterion 1, the mean difference ±SD between the test device and reference BP readings (N = 255) was 1.3 ± 6.5/3.6 ± 5.9 mmHg (systolic/diastolic; threshold ≤5 ± 8 mmHg). For Criterion 2, the SD of the averaged BP differences between the test device and reference BP per individual (N = 85) was 5.70/5.25 mmHg (systolic/diastolic; threshold ≤6.82/5.89 mmHg).

CONCLUSIONS: The automated oscillometric home BP monitor AVITA BPM82 comfortably fulfilled all the requirements of the AAMI/ESH/ISO Universal Standard (ISO 81060-2:2018) and its Amendment 1.2020-01 in a general population and can be recommended for clinical use.
