调息对人体植物神经功能影响的微机测定系统及临床应用

THE EFFECT OF VARIANT RESPIRATORY MODEL ON HUMAN AUTONOMIC NERVE FUNCTION TESTED BY A COMPUTER SYSTEM AND ITS CLINIC APPLICATION

设计的人体植物神经功能检测系统中的软件部分系用编译BASIC语言和宏汇编语言编制,有较高的运算速度。它包括心率转换模块、滤波与频谱分析模块、绘图模块、面积计算模块、计算参数模块及呼吸信号处理模块。本系统可计算反映人体植物神经功能的心率功率谱、连续R-R间期的变异系数(CV)、标准差(SD)、差平方均值(MSSB)等多种参数。可用于研究不同呼吸模式对人体植物神经功能的影响。

A computer system had been developed which can measure the interaction of sympathetic and parasympathetic nerve in human autonomic nerve function.The software in the system is written with BASIC and assem-ble language,so it has fast calculating velocity.The software includes six moduls,that is,heart rate transfer module,digital filter and spectrum analysis module,drawing picture module,area counting module,calculation parameter module and handling respiratory signal module.The system has the ability to calcuIate many coefficient,such as,HR spectrum,coefficient of variation(CV),standard deviation(SD)and mean square substract(MSSB) of R-R deliver,A new way is obtained in this paper by which we can observe how variant respiratory models affect the autonomic nerve functions in the human.
