我们开发了一种灵活的生理监测和分析系统，用于生理研究，其中数据可以在较长的时间内获得。我们的系统使用低成本的个人计算机硬件集中现有的多个监测设备的数据。所有监控参数都显示在一个屏幕上，并记录在一个文件中。该系统通过提供生命体征的连续显示来自动化生理记录保存的过程。此外，当生命体征超出可接受范围时，会产生声音和视觉警报，提示实验者采取纠正措施。该系统的中心元素是在IBM PC兼容计算机上以专用方式运行的程序。该程序是用C语言编写的，并利用图形库在PC的任何标准显示器上真实的显示轨迹和分析结果。该程序通过最初阅读配置文件将A/D板的模拟通道分配给特定的生理参数，该配置文件还描述了每个参数的报警条件和分析例程。所有硬件特定的代码都被隔离到定义良好的模块中。该程序是高度灵活的，对于不同的参数集和高度便携式不同的实验和计算机环境。
We have developed a flexible physiological monitoring and analysis system for physiological studies in which data are obtained over extended periods. Our system uses low-cost personal computer hardware to concentrate data from existing multiple monitoring devices. All monitored parameters are displayed on a single screen and recorded in a single file. The system automates the process of physiological record keeping by providing continuous displays of vital signs. In addition, audible and visual alarms are produced when vital signs are outside of acceptable ranges, prompting the experimenter to take corrective actions. The central element of the system is a program running in a dedicated manner on an IBM PC-compatible computer. The program is written in the C language and makes use of a graphics library to display traces and analysis results in real time on any standard display for the PC. This program assigns the analog channels of an A/D board to particular physiological parameters by initially reading a configuration file, which also describes the alarm conditions and analysis routine for each parameter. All hardware specific code is isolated into well-defined modules. The program is both highly flexible with regard to different sets of parameters and highly portable for different experimental and computer environments.
