本文介绍了新生儿心肺功能监护仪的软硬件设计，该仪器具有体积小，功能全面，适用性广，操作简单等特点，能可靠地实现对新生儿的监护。用该仪器对新生儿的血氧饱和度和心率这两个最重要的生理参数的测定获取了中国新生儿呼吸系统的数据。对数据的统计分析表明，血氧饱和度和心率都属于正态分布，并依此给出了中国新生婴儿的这两个参数的分布范围。%In this paper we describe the hardware and software design of a neonate respiratory system. The instrument has features of compact structure, complete function, easy-to-sue in a wide range and can implement reliable monitoring of newborn. Using the system, two most important parameters of neonates were obtained. Through statistics analysis, it is proved that the SpO2 and heart rate are both of normal distribution. Meanwhile, in this article the range of distribution of the two parameters of Chinese neonate are also given.
