Clinical Evaluation of Bionet Sphygmomanometer Module BN1 Based on ISO 81060-2:2018 Protocol
In Brief
A clinical study evaluating Blood pressure measurement group for Blood Pressure. Completed, enrolled 86 participants across 1 site.
Detailed Summary
According to INTERNATIONAL STANDARD (hereafter ISO) blood pressure (BP) monitor clinical evaluation protocol (ISO 81060-2:2018, Non-invasive sphygmomanometers- Part2: Clinical investigation of intermittent automated measurement type) for BN1 (BNiBP), an electronic sphygmomanometer module newly developed by Bionet Co., Ltd., the clinical group and evaluation criteria presented in, the effectiveness of blood pressure measurement performance was evaluated. The auscultation method used as a reference (gold standard) of a non-invasive blood pressure (NIBP) measurement method was used. The first blood pressure measurement was performed once each (reference BP not used for evaluation, R0; test BP not used for evaluation, T0) with auscultation and the test medical device (BM5 equipped with BN1 (BNiBP)). The blood pressure used for evaluation was measured four times by auscultation (first reference BP to fourth reference BP, R1 to R4) and three times by the test medical device (first test BP to third test BP, T1 to T3) alternately. A minimum interval of 1 min was allowed between each blood pressure measurement. Three data pairs (mean value of R1, R2 \& T1 / R2, mean value of R3 \& T2 / R3, mean value of R4 \& T3) were obtained from one study subject. This study aims to verify that the mean value of the differences and standard deviations of data pairs meet the criteria of ISO 81060-2:2018.

Interventions
In this study, the protocol applied to automatic electronic blood pressure system module BN1 for performance evaluation is ISO's proposed "ISO 81060-2:2018 Non-invasive sphygmomanometers- Part2: Clinical investment of internal automatic measurement type". The initial BP measurement is performed alternately, measuring the blood pressure by the measurer and the test device once each, and measuring blood pressure by the measurer four times by the observer and three times by the test device.
