Abstract

Process and apparatus for patient danger recognition and forecasting, particularly for the intensive medical care of the patient. The invention uses various variables to set up a danger function that represents the probability of occurrence of a danger condition, forms average values of the danger function throughout subsequent time periods that are shorter than the time required for a medical intervention, by comparing the formed average values with levels of increasing sequences of threshold values, providing an indication associated with the highest exceeded threshold value, using the average values to set up a regression function which approximates the sequence thereof, determining a subsequent extrapolated value of the function for the next time period that represents a forecast average value of the danger function, and indicating the extrapolated value provided it is higher than a predetermined level. Preferably three threshold values are used in the comparing step, with magnitudes of 40, 60 and 80% of the danger function, respectively.
