提出了一种无创伤测量动脉血氧饱和度(SaO_2)的新方法.根据脉搏血氧测定原理设计了传感器、放大电路和采用Intel 8098单片机为核心的信号处理系统.给出了动物缺氧实验结果和初步的临床应用测定的结果.实验结果表明设计方案与目前临床使用的AVL945血气分析仪有很好的相关性.
A new method of noninvasive measurement of arterial oxygen saturation (SaO_2) is proposed.The sensor, amplifying circuit and signal processing system using Intel 8098 as the core are designed according to the principle of pulse oximetry.The experiment of animal hypoxia Results and preliminary results of clinical application of the results of the experimental results show that the design and clinical use of AVL945 blood gas analyzer has a good correlation.
