End tidal CO 2 (etCO 2)registered before and after High frequency jet ventilation (HFJV) phase (etCO 2 - pre jet and post jet), Respiratory pressures on conventional tidal volume ventilation before and after HFJV phase, expressed in cm.H 2O: peak inspiratory pressure (PeakP) pre jet, mean airway pressure (MaP) pre jet, dynamic lung compliance both before and after HFJV phase (Compliance pre and post jet) as well as tidal volumes on conventional lung ventilation, at liver displacement measurement point (TV post jet). HFJV ventilator settings: respiratory frequency (FQ on jet) and target driving pressure (T-DP on jet) as well as the measured respiratory parameters: peak inspiratory pressure (PIP) and mean airway pressure (MaP) and maximum end tidal carbon dioxide tension during HFJV phase (Max etCO 2 on jet).
