To overcome the present limitations of simple threshold alarms, an automatic real-time trend analysis system is being developed to warn about slowly varying trends or short interval disturbances before the underlying condition results in a critical situation. A rule based approach is adopted to help in the detection and diagnosis of critical patient conditions. The first level performs low-level trend analysis based on median and FIR filters. A second module detects and displays symptomatic patient conditions using a decision tree of rules to process the data from the first module. The third module displays the processed data and symptoms generated to help the user interpret the advisory diagnosis.
