Osmotic effect on the hematocrit under the hypertonic condition

We have studied the hematocrit under the hypertonic condition, on the basis of theoretical considerations and available experimental data, for swine red cells and ghosts. Experimentally obtained exponential behavior for red cells and quadratic behavior of the hematocrit for ghosts were explained reasonably by the theory. From fittings of experimental data to the theoretical equations, elastic coefficients of red blood cells and red cell ghosts, both near the isotonic condition and in the high osmolarity range, were determined.
