AbstractA method of determining a quantitative statement concerning the quality of a medical measurement signal in pulsoximetry includes the steps of determining factors relevant to the measurement signal and interlinking the factors by means of an uncertain logic into a quality indicator. The factors relate to combinations selected from the group consisting of signal recording, signal processing, and signal evaluation. The uncertain logic includes fuzzy logic. The quality indicator quantitatively describes a quality of a determined measurement value of the measurement signal.
