In this paper, a framework for an intelligent bedside monitor is prese
nted. The monitor derives an abstraction of the current status of a pa
tient by performing fuzzy state transitions on pre-processed input con
tinuously supplied by clinical instrumentation. So far, an implementat
ion called DiaMon-1 has been used for off-line evaluation of data of p
atients suffering from the adult respiratory distress syndrome (ARDS).
