The influence of oxygen conditions on the RBC deformability for the same individual RBCs. (A and B) Longitudinal tracking of the changes in shear modulus μ and shear viscosity η after a single DeOxy switch between different oxygen levels 17.5% O2
vs 0% O2 and 17.5% O2
vs 5% O2, respectively. (C and D) Comparison of the progression of μ and η values between two different cyclic deoxygenation conditions: 17.5% O2 - 5% O2 and 17.5% O2 - 0% O2. * p < 0.05, ** p < 0.01, *** p < 0.001, **** p < 0.0001, n.s., not significant.
