비침습 자동혈압계 성능평가를 위한 시뮬레이터 개발

Abstract

Blood pressure is one of important vital signs for monitoring patients’ medical conditions. Automated non-invasive blood pressure (NIBP) measurement devices calculate systolic and diastolic blood pressures from the oscillation in cuff pressure caused by periodic motion of artery. In order to verify the performance of NIBP devices, we developed a simulator capable to regenerate the oscillometric waveform obtained human subjects. The simulator provided pressure pulses to device-under-test and device readings were compared to the auscultatory references. By the performance verification of NIBP devices, the reliability of blood pressure measurement would be enhanced.
