Abstract
Das verbesserte Verfahren für Blutgasanalysesensoren erhöht unter Berücksichtigung der Gewebeperfusion mit Blut durch eine Lichtabsorptionsmessung die Messwertgenauigkeit von Pulsoxymetern, die zur Bestimmung der arteriellen Sauerstoffsättigung des Blutes eingesetzt werden. Durch die Injektion von medizinischen Farbstoffen kann eine Eichung für ein Pulsoxymeter über den gesamten Sättigungsbereich am Menschen simuliert werden.
