Abstract

Objectives

This study aimed to evaluate the accuracy of the Beneware model ABP-021 oscillometric blood pressure monitor in the general population according to the European Society of Hypertension International Protocol (ESH-IP). The accuracy of the device was assessed in relation to various clinical variables, including age, sex, BMI, and arm circumference.

Methods

Thirty-three individuals (18 men and 15 women), with a mean age of 36±14 years (age range: 20–68 years), were studied according to the recommendations of the ESH-IP. Sequential same-arm blood pressure measurements were performed, alternating between a mercury standard and the automatic device. The differences among the test–control measurements were assessed and divided into categorization zones of 5, 10, and 15 mmHg discrepancy.

Results

The device complied with the quality requirements of the ESH-IP. The device–observer disagreement was −1.2±4.7 mmHg for systolic blood pressure (SBP) and −1.7±4.3 mmHg for diastolic blood pressure (DBP). The device produced 77, 93, and 98 measurements, respectively, within the 5, 10, and 15 mmHg discrepancy limits for SBP. For DBP, 80, 97, and 99 measurements were observed within the 5, 10, and 15 mmHg discrepancy limits. The number of participants with two or three of the device–observer differences within 5 mmHg was 26 for SBP and 29 for DBP, whereas there were only two participants with no device–observer differences within 5 mmHg for DBP.

Conclusion

These data show that the Beneware model ABP-021 monitor meets the requirements of the ESH-IP, in static conditions, indicating its suitability for measuring blood pressure in the general adult population.
