Investigating the inaccuracies of indirect method of blood pressure measurement associated to the cuff constructing fabrics

Numerous cuffs have been manufactured using different materials in which textile fabric is the main constituent. There are no specific guidelines for selection of cuff and its design. In this investigation, five types (made woven non-woven fabrics) were selected, their pressure distribution was noted while mimicking process blood measurement. It achieved by measuring at interface selected a bare metal cylinder. I-scan, an measurement system employed to record profiles under against 140 mmHg 40 inside cuffs. The data obtained from sensing processed MATLAB examine 96 points detail. results show that registered non-uniform also non-identical among found be lower than cuff, shows attenuates as transfers surface object underneath it. range difference varies 10 15 mmHg. This study indicates depends on constructing properties. concluded there need select appropriate with optimized properties desired may lead accurate estimation pressure.
