ABSTRACT
In order to determine the interdependence of the parameters of the respiratory gas transport in rat blood (Sprague-Dawley) CO-2-equilibration curves in fully oxygenated and deoxygenated blood are measured. The results are presented in the form of pH-log P-CO-2-diagrams. O-2-dissociation curves of rat blood are registered at different CO-2 partial pressures. The P-02 at S-02 equals 50% ranged between 27.7 mm Hg for P-C0-2 equals 20 mm Hg. 35.1 mm Hg for P-C0-2 equals 40 mm Hg and 42.2 for P-C0-2 equals 60 mm Hg. Cartesian and alignment nomograms are constructed using CO-2 equilibration curves and O-2 dissociation curves. These nomograms give the interrelations between P-O-2, P-CO-2, pH and S-0-2 of rat blood. Separate nomograms are presented for Hb-concentrations of 10-13 g-% and 13.1-16 g-% because of great variations of Hb concentration in rat blood. If two of these values are known the nomograms permit the reading of the remaining paramters.
