Ein Nomogramm für die O2-Abhängigkeit des Säure-Basen-Status im menschlichen Blut

  • G. Thews


Es wird ein neues Nomogramm für das menschliche Blut vorgelegt, das die Abhängigkeit des gesamten Säure-Basen-Status vom Oxygenationsgrad des Hämoglobins übersichtlich darstellt. Das Nomogramm soll insbesondere dazu dienen, bei Kenntnis des O2-Druckes, des CO2-Druckes, des pH s -Wertes und des Hb-Gehaltes folgende Größen ohne besondere Rechnung zu ermitteln: O2-Sättigung, aktuelles Bicarbonat, Gesamt-CO2, Basenüberschuß, Basenüberschuß bei voller Oxygenation, Pufferbasen, Standard-Bicarbonat, Standard-pH s . Der Gebrauch und die Aussagemöglichkeiten des Säure-Basen-Nomogramms werden erläutert.


A new nomogram for human blood is presented, which depicts, in simple fashion, the dependence of the total acid-base status on the degree of oxygenation of the hemoglobin. When O2 tension, CO2 tension, pH s value and Hb concentration are known, the nomogram is of particular use in giving the following values without special calculation: O2 saturation, actual bicarbonate, total CO2, base excess, base excess for complete oxygenation, buffer base, standard bicarbonate and standard pH s . The method of using the acid-base nomogram, together with its application potential, are explained.
