From: Moderately high frequency ventilation with a conventional ventilator allows reduction of tidal volume without increasing mean airway pressure

Figure 2

Respiratory variables during the ventilatory modes tested. (A) PaCO2 (mmHg; Friedman’s test, p = 0.011). (B) Tidal volume (mL/kg; Friedman’s test, p < 0.001). (C) Plateau pressure (cmH2O; Friedman’s test, p < 0.001). (D) Driving pressure (cmH2O; Friedman’s test, p < 0.001). VT, RR, HFPPV, and HFOV denote tidal volume, respiratory rate, high-frequency positive-pressure ventilation, and high-frequency oscillatory ventilation, respectively. The whiskers denote the P10th and P90th. *Student-Newman-Keuls’ post hoc analysis, p < 0.05 vs stabilization step (VT = 6 mL/kg and RR = 35 breaths/min); #Student-Newman-Keuls’ post hoc analysis, p < 0.05 vs HFPPV = 150.
