Abstract
Our host computer system (HP PDMS) was linked by four subsystems using personal computers, designed by ourselves. In these systems, a multi-patients respiratory, anesthetic and metabolic scanned monitoring system (RAMSCAN named by us) was used most frequentry in our operating rooms.
All functions of RAMSCAN start at the timing of "power on". For example, users don't need to touch the key board for feeding patient ID to the computer. Host computer can accept the monitoring data from RAMSCAN, using the message including room No. s and measuring times.
We concluded that successful acceptance of RAMSCAN in clinical anesthesia came from its human interface, leaving out keybord input and many conections, between bedside terminal of RAMSCAN and vital sign monitors.
Now (1987.), this system in renewing because of its longterm (9 years) use. The futures of the new system are following; 3 long sampling line per a patient; a gas wave sharpner using a technique of analogue computation; a local area network (omni-net). Almost of these futures come from our developments during 9 years.
