The respiratory gas values of the fetal and maternal blood in cartesian nomograms

Respiratory gas values of maternal and fetal blood taken at delivery are represented in two Cartesian nomograms. They are based on data, published by vogel, fischer und thews (1965) and Fischer, Vogel und Thews (1965). The nomograms depict the interdependence of O 2 pressure, O 2 content, CO 2 pressure and CO 2 content, established by the O 2 and CO 2 dissociation curves, as well as by the Bohr effect and the Haldane effect. If two of the values are known, the remaining ones can be read from the nomograms.
