Abstract

Objective

The aim of this study was to assess the accuracy of the single-cuff oscillometric blood pressure (BP) monitor InBody BPBIO320 developed for self-measurement by adults in public spaces according to the 2010 European Society of Hypertension International Protocol (ESH-IP).

Participants and methods

Adults were recruited to fulfill the ESH-IP requirements. The same-arm sequential BP measurement method was used.

Results

A total of 38 participants were recruited and 33 were included in the analysis. The average difference between test and reference BP measurements was−0.4±5.3 (SD)/−0.5±4.6 mmHg (systolic/diastolic). The number of test–reference BP differences within 5, 10, and 15 mmHg was 73, 91, and 98 for systolic BP and 79, 93, and 99 for diastolic. The number of participants with at least two of their three BP differences within 5 mmHg was 28 for both systolic and diastolic BPs. The number of participants with none of their three BP differences within 5 mmHg was 1 for both systolic and diastolic BPs.

Conclusion

The InBody BPBIO320 device fulfilled the requirements of the ESH-IP validation protocol and can be recommended for clinical use in adults.
