  1. Values are stated as mean ± SD. Baseline, baseline measurements (consisting of volume-controlled ventilation); VCV Volume-controlled ventilation, FCV Flow-controlled ventilation, VT tidal volume, VT PBW tidal volume per predicted body weight, VF Ventilation frequency, PPlat Plateau pressure, Pmean mean tracheal pressure, Pmean expiration mean tracheal pressure during expiration, CRS Respiratory system compliance, MAP Mean arterial pressure, SpO2 Peripheral oxygen saturation, FiO2 Fraction of inspired oxygen, pvent p for ventilation mode* = p < 0.001 for FCV vs. baseline and for # = p < 0.001 for FCV vs. VCV. Linear mixed effect model analyses were used to check for differences between the ventilation phases using R based software (jamovi project 2018, version 0.9.2.3). The randomization had no significant effect on the measured respiratory and hemodynamic variables
