A mathematical prognostic in which changes in a number of physiologically significant factors are measured and interpolated to determine a "damage function" incident to bacterial infection or other serious inflammation. By measuring a large number of physiologically significant factors including, but not limited to, Interleukin 6 (IL6), Interleukin 10 (IL10), Nitric Oxide (NO), and others, it is possible to predict life versus death by the damage function, dD / dt, which measures and interpolates differential data for a plurality of factors.
