Abstract

A medical alarm system for processing physiologic and laboratory data in hospitals and other environments is disclosed. The alarm system provides early detection of complex pathophysiologic cascades. The alarm system detects aggregated timed patterns of inflammatory indicators, metabolic, pulse, blood pressure, oxygen saturation, and/or ventilation trends to detect expanding cascade patterns characteristic of, for example, progressive sepsis. The system may include a processor programmed to convert at least the physiologic and laboratory data of a patient into a predetermined format favorable for searching. The system may also include a processor programmed to search the formatted data to detect the progressively expanding global patterns of abnormal data characteristic of evolving sepsis and/or septic shock. The alarm system may be configured to provide an early warning for healthcare workers when a pattern indicative of progression of a complex pathophysiologic cascade is detected.
