Mechanical lung airflow and muscular pressure at high pressure triggering. Mechanical lung airflow Q _p and muscular pressure P _mus measured at time T _h at which the pressure rise is triggered, for every breathing dynamics tested. Each segment represents the values measured for one given P _0.1 (increasing from the left to the right) and all breathing frequencies. All ventilators were set to the maximum pressure rise triggering sensitivity
