"WebTherefore, we examined osmotic RBC deformability over a range of shear stresses (0.5-20 Pa). We found that the RBC deformability at low shear stresses (1-3 Pa) was maximum in hypotonic conditions (225-250 mOsm/kg H2O), which is slightly lower than the normal range of osmolality in plasma (290-310 mOsm/kg H2O).
