目的：我们报告在一个大型的临床和研究睡眠实验室的数字处理的实施。该系统包括睡眠期间收集的生理信号的数字收集、显示、分析和储存库。研究方法：在描述了原来的模拟系统，计算机设备和软件的数字实现所需的，我们解释我们的快速眼动（REM）和δ波检测算法。最后，我们描述了一个实验验证数字显示和分析系统。结论：睡眠信号的数字化处理节省了计算机操作人员、多导睡眠图技术人员和计算机时间。它还节省了多导睡眠图纸和FM磁带等资源。数字信号适用于大量的分析技术，并提高了信号质量。通过数字处理的自动REM和δ波检测与快速眼动和δ波的视觉计数高度相关。
Objectives: We report on the implementation of digital processing in a large clinical and research sleep laboratory. The system includes the digital collection, display, analysis, and repository of physiological signals collected during sleep. Methods: After describing the original analog system, the computer equipment and software necessary for the digital implementation are presented and we explain our algorithms for rapid eye movement (REM) and delta-wave detection. Finally, we describe an experiment validating the digital system of display and analyses. Conclusions: The digital processing of sleep signals saves computer operator, polysomnographic technologist, and computer time. It also saves resources such as polysomnographic paper and FM tape. The digital signals lend themselves to a large array of analysis techniques and result in improved signal quality. Automated REM and delta-wave detection via digital processing correlate highly with visual counts of rapid eye movements and delta waves.
