Pressure waveform supplied by the mechanical ventilator over the simulation time for all the RMs implemented in this study. (A) Maximal recruitment strategy with a final PEEP value of 10 cm H2O (MRS-10), (B) Maximal recruitment strategy with a final PEEP value of 5 cm H2O (MRS-5), (C) Sustained inflation with a final PEEP value of 10 cm H2O (SI-10), (D) Sustained inflation with a final PEEP value of 5 cm H2O (SI-5), (E) Prolonged recruitment maneuver with a final PEEP value of 10 cm H2O (PRM-10), (F) Prolonged recruitment maneuver with a final PEEP value of 5 cm H2O (PRM-5). From the plots, pressure at the end of expiration (that is the minimum pressure during a breath or in this case the PEEP setting) and peak inspiratory pressure (set by the ventilator) can be inferred. The MRS plots (A and B) indicate the recruitment and the PEEP titration phases. PEEP, positive end-expiratory pressure; RM, recruitment maneuver.
