Abstract (en)
[origin: WO0077659A1] The invention relates to the determination of a quantitative statement concerning the quality of a measurement signal such as a medical measurement signal used in the area of pulsoximetry by: determining measurement signal-relevant factors, preferably with regard to the recording of the signal; processing and/or evaluating the signals, and; using an uncertain logic, preferably fuzzy logic, to establish a link between the determined factors and a quality indicator which quantitatively describes the quality of the determined measured value. In addition, a control of an alarm function according to the quality indicator preferably ensues, preferably when the measurement signal deviates from a predetermined limiting value or range.
