Abstract

An evaluation unit (100) classifies a current treatment situation for a signal connected medical system. A receiving module (110) receives a plurality of treatment signals (112) that indicates a value (116) for a patient parameter (115) and a signal quality. A processing module stores values of patient parameters received at past times with a respective time stamp (125) indicating the time and a quality index (127) assigned to the respective value or group of values and detects a presence of a trigger signal (124) and calculates an evaluation score (134) using a stored calculation rule (132). The calculation uses the stored values of patient parameters as a function of the respective time stamp. The processing module calculates a quality indicator (138) using a stored quality metric (136) depending on the associated quality indices of the values of patient parameters necessary for the calculation of the evaluation score.
