Report 79 05 Knowledge Engineering for Dynamic Clinical Stanford Settings Giving Advice in the Intensive Care Unit . Lawrence M. John C. a

As the patient setting changes--e.g., as a patient starts Lo breathe on his own during removal (weaning) from the ventilator--the same measurement values lead to different interpretations. In order to properly interpret data collected during changing therapeutic contexts, the knowledge base includes a model of the stages that a patient follows from admission to the unit through the end of the critical monitoring phase. Recognition of the appropriate patient context is an essential step in determining the meaning of most physiological measurements. The program maintains a description of the current and optimal ventilatory therapies for any given time. The list of states and possible state transitions are represented in Figure 1.
