Abstract

The complexity of the temperature curve was measured by means of ApEn (Approximate Entropy) in 16 critically ill patients, admitted to the Intensive Care Unit in multiorgan failure. ApEn was significantly lower (the temperature curve was less complex) in patients who died versus patients who survived. The predictive value of ApEn compares favourably with conventional scales of physiological status (Sepsis Organ Failure Assessment)

 Key words:    Complexity, temperature curve, multiorgan failure, Approximate Entropy .
