Preprocessing of temperature signals. Raw (a) and detrended (b) temperature curve versus time of recording (minutes) in a patient with ventilator-associated pneumonia and septic shock. The signal average value is subtracted, so that features are not biased by the temperature mean values (1a). Other normalization procedures were also considered, to isolate the long-term trends in the signal (by use of detrend, 1b).
