CMV: Controlled mechanical ventilation; RR_CMV: Respiratory rate under CMV; V_T,CMV: Tidal volume under CMV; P_plat,CMV: Plateau pressure under CMV; PEEP: Clinically selected positive end-expiratory pressure; RR_PSV: Respiratory rate under pressure support ventilation (before the start of the PEEP wave maneuver); V_T,PSV: Mean tidal volume during pressure support ventilation before the start of the PEEP wave maneuver; PS: Pressure support during PSV; WOB: Patient work of breathing during undisturbed PSV.
