Table 3 Subset of studies reporting the rheometric characterisation for healthy, CF and COPD-affected sputum. Classification according to experimental protocol followed. The symbol \(\eta\) represents apparent viscosity, \(\dot{\gamma }\) is the shear rate, \(\omega\) is the frequency of deformation (oscillatory shear), \(\gamma\) is the strain (for steady and oscillatory shear), and J symbolises the compliance.
\(\eta\) vs \(\dot{\gamma }\) | \(G'\),\(G''\) vs \(\omega\) | \(G'\),\(G''\) vs \(\gamma\) | Lissajous | \(\eta\) vs t | J vs t | \(\gamma\) vs t | Hysteresis | |
