Abstract

Beschrieben wird die Ermittlung einer quantitativen Aussage über die Qualität eines Meßsignals, wie eines medizinischen Meßsignals in der Pulsoximetrie, durch Ermittlung von Meßsignal-relevanten Faktoren, vorzugsweise bezogen auf die Signalaufnahme, Signalbearbeitung und/oder Signalauswertung, und Verknüpfung der ermittelten Faktoren durch eine unscharfe Logik, vorzugsweise der Fuzzy-Logic, zu einem Qualitätsindikator, der quantitativ die Qualität des ermittelten Meßwertes beschreibt. Vorzugsweise erfolgt weiter eine Steuerung einer Alarmfunktion in Abhängigkeit des Qualitätsindikators, vorzugsweise bei Abweichen des Meßsignals von einem vorgegebenen Grenzwert oder -bereich.
