Primary Outcome Measures

Name	Time	Method
To evaluate if cardiac surgery can reduce the respiratory effort as assessed through the diaphragm ultrasonogaphy[The enrolled patients will undergo to a sonographic measurement of diaphragmatic motion to assess the diaphragm thickening fractio (TF) the day before surgery, during the weaning trial daily before extubation, and the day after the weaning trials and at the patient discharge. ];To evaluate if cardiac surgery can reduce the respiratory drive as assessed through the diaphragm ultrasonogaphy[The enrolled patients will undergo to a sonographic measurement of diaphragmatic motion to assess the diaphragm craniocaudal displacement the day before surgery, during the weaning trial daily before extubation, and the day after the weaning trials and at the patient discharge. ]

Secondary Outcome Measures

Name	Time	Method
To evaluate the diaphragmatic dysfunction evolution until the patient discharge[Ultrasound diaphragm assessment (i.e. diaphragm displacement and thickening fraction) will be done the day before surgery, during the weaning trial, the day after the weaning trial daily before extubation and at the patient discharge];To assess the rate of severe diaphragmatic dysfunction, measured like a diaphragmatic excursion trough diaphragmatic ultrasound less than 10mm during normal spontaneous breathing[After extubation]
