The oxygenation velocities of the red cell and Hb were studied by means of the rapid flow method with 7 normal subjects. The So2 was measured by taking the difference in transmitted light intensities at two wave lengths, so that the influence of the uneven scattering could be excluded fairly well.
The oxygenation velocities were mainly measured over the So2 range from 70 to 100%, and they were expressed by the velocity factor. As to the velocity factor of Hb, Fs, the same result as shown in the preceding paper was confirmed in this study. That is, Fs was proportional to (100-So2)1.6. On the other hand, the velocity factor of the red cell, Fc, was clarified to be given by
