Mean pressure rise duration \(\tilde {\tau }_{\text {pr}}\). Range of the pressure rise duration \(\tilde {\tau }_{\text {pr}}\) measured for the nine ventilators connected to the restrictive (blue) and obstructive (red) lung models when the corresponding parameter is set to its smallest and largest values
