Percentage change in $\overline{\Delta P_{\text{int}}}$ as a function of C in relation to steady flow. All experiments were completed at a high frequency (1 Hz) and a fast flow (0.1 mL/min). Note that in all oscillation modalities (Sym, FR, FF), $\overline{\Delta P_{\text{int}}}$ is significantly reduced at very low C, with FF eliciting a far greater reduction in the reopening pressures.
