When, in 1975, it became clear that the existing PDP-9 based general ICU monitoring system would soon be obsolete, or rather that the maintenance for it would be too expensive, work started on defining its successor: the Unibed system. The system was designed as a hierarchical network of microcomputers [1] and developed in close cooperation with the medical and nursing staff. The base level is made up of a single type of unit, the Unibed [2]. Each Unibed combines the functions of front end and signal processing and can be used completely stand-alone. In practice, however, one or more Unibeds are usually coupled via a standard serial link to another microcomputer at the nurse station to provide time-trend graphics, strip recording, alarm setting, and other centralized functions. The nurse station in its turn may be linked to a higher level, say, for data-base and long-term statistics.
