Abstract
The oxygenation velocity of the red blood cell was studied by means of a rapid flow method by varying the flow velocity through an observation tube with blood samples from five normal human subjects. The flow velocity was fixed at three different levels of 294, 147 and 74cm·sec-1. The oxygenation velocity was measured over an SO2 range from 0 to about 70% and the velocity was expressed by the velocity factor described by MOCHIZUKI.
The Fc value increased with the flow velocity linearly at a low velocity range, but at a higher velocity range the rate of its increment decreased gradually. From the experimental facts the following conclusion was derived: The O2 diffusion into the red blood cell is resisted dominantly by a boundary layer having a transfer coefficient which is strongly affected by convection around the cell surface.
