- W1484358001 abstract "본 연구에서는 동맥혈액 내의 혈액가스(pH, <TEX>$pCO_2$</TEX>, <TEX>$pO_2$</TEX>)를 측정할 수 있는 휴대용 혈액가스 분석 시스템을 구현하였다. 구현된 시스템은 크게 하드웨어부와 소프트웨어부로 구분하였으며, 하드웨어부는 메커니즘과 전자회로부로 구분하여 설계하였다. 소프트웨어부는 각 모듈별로 작성하였으며, 운용프로그램, 세척프로그램, 교정프로그램, 측정프로그램 등으로 구성하였다. 그리고 시스템의 정확한 교정을 위하여 2점 교정방식을 사용하였고, 1점 보정방식을 추가 적용하여 측정의 정확성을 높이고자 하였다. 시스템의 평가를 위하여 각 전극의 감응특성을 조사하였다. 그리고 정확도 평가를 위하여 표준용액을 이용하여 측정실험을 하고 통계적인 분석을 하였다. 그 결과 계수변화율이 1.12이내이었고, 최대오차가 1.298%이내인 정확도를 나타내었으며, 휴대형 ABGA의 개발 가능성을 확인하였다. In this study, we implemented the measurement of pH, <TEX>$pO_2$</TEX>, <TEX>$pCO_2$</TEX> of the arterial blood on a portable blood gas analysis system. This system is consist of two parts of hardware and software. The hardware part is divided into a fluidic mechanism and an electronic circuit unit. The system program is composed of operating, washing, correcting, and measuring routines. Both of 1-point and 2-point calibration schemes were used to enhance the accuracy of the measurement. In order to evaluate the performance of the developed system, we measured and performed statistical analysis on the characteristics of the sensing electrode response. As a result, coefficient variation was within 1.12, and maximum error was within 1.298%. We confirmed development possibility of portable blood gas analyzer." @default.
