Furthermore, the linear regression lines of R0 vs Rmax, and R0% vs Rmax%, were not significantly different from the identity line. These results demonstrate that resistive impedance extrapolated at zero frequency is equivalent to maximal resistive impedance, and can be proposed as an index, not only of the level of airway obstruction, but also of its reversibility.
