Intervention

Procedure:
• Protective ventilation implementation
In this condition, we will implement the protective ventilation related with gender and height . A blood gas will be performed at before protective ventilation implementation and at the end of this condition.Time condition 30 minutes
• Protective ventilation with HME
In this condition, the patient will received protective ventilation with a Heat Moisture Exchanger (HME). A blood gas will be performed at the end of this condition.Time condition 30 minutes
• Protective ventilation with Heated humidifier
In this condition, the patient will received protective ventilation with a Heated humidifier. A blood gas will be performed at the end of this condition.Time condition 30 minutes
• Tidal Volume reduction
n this condition, we will reduce Tidal volume (with smartphone application calculation) to obtain the same alveolar ventilation (PaCO2) obtained on the HME condition

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	PaCO2 Variation	The primary outcome is to evaluate the PaCO2 variation at the end of condition 2 (after 30 minutes with protective ventilation+ HME) and condition 4 (30 minutes after Tidal volume reduction + Heater humidifier).; Variation <= 10% of PaCO2	60 minutes post intervention
Primary	PaCO2 Variation	The primary outcome is to evaluate the PaCO2 variation at the end of condition 2 (after 30 minutes with protective ventilation+ HME) and condition 4 (30 minutes after Tidal volume reduction + Heater humidifier).; Variation <= 10% of PaCO2	120 minutes post intervention
Secondary	Correlation between PCO2 variation and alveolar ventilation variation	We will compare PaCO2 level variation and the alveolar ventilation variation to establish correlation.; Correlation variation under 10% will be significative	60 and 90 minutes post intervention
Secondary	Hemodynamic impact vs pH	Cardiac echographic measurement (LeftVentricularEjectionFraction) in relation with acidosis status	Baseline, 30, 60, 90 and 120 minutes post intervention
Secondary	Hemodynamic impact vs pH	Cardiac echographic measurement (RightVentricularEjectionFraction) in relation with acidosis status	Baseline, 30, 60, 90 and 120 minutes post intervention
Secondary	Hemodynamic impact vs pH	Cardiac echographic measurement Arterial pulmonary pressure) in relation with acidosis status	Baseline, 30, 60, 90 and 120 minutes post intervention
