Technical and organisational aspects of the setup of an analog/digital conversion are discussed in the light of two clinical reference installations. The first example deals with a closed loop regulation system used to control a cardio-surgical intervention. This setup works with repeated turns of acquisition and evaluation. The second example describes a comprehensive haemodynamic beat-by-beat analysis, involving data acquisition from FM-coded tape, preprocessing on the PC, file transfer to a mainframe and a detailed statistical and graphical evaluation within the package SAS. Special attention is given to certain technical issues and to criteria of performance. Finally, setup procedures are suggested which may help in the avoidance of certain insufficiencies which are likely to occur in a first attempt to establish A/D conversion within clinical research projects.
结合两个临床参考装置，讨论了模拟/数字转换设置的技术和组织方面。第一个例子涉及用于控制心脏外科手术干预的闭环调节系统。该设置通过重复的采集和评估循环工作。第二个例子描述了全面的逐搏血流动力学分析，包括从调频编码磁带采集数据、在个人电脑上进行预处理、将文件传输到主机以及在SAS软件包内进行详细的统计和图形评估。特别关注了某些技术问题和性能标准。最后，提出了设置程序，这可能有助于避免在临床研究项目中首次尝试建立模数转换时可能出现的某些不足。
