Macrorheology of human cystic fibrosis sputum. (A) The frequency dependent elastic, G’(ω), and viscous moduli, G”(ω), of CF samples (n=6) were recorded at a constant strain amplitude of 1%. (B) Strain-dependent elastic, G’(ω), and viscous moduli, G”(ω), from 0.1–100% strain amplitude. (C) The steady state viscosity of CF sputum at shear rates between 10− 2−102 rad/s. Physiological rates in the normal lung are represented by the dotted line. Inset: viscosities of individual CF sputum samples at physiological shear rates. Figure obtained from ref [14].
