Efficacy and Safety of Using Noninvasive Ventilation Associated With Recruitment Maneuver in Cardiac Surgery.

After extubation the patient who was randomized to the Recruitment Group will use noninvasive ventilation (NIV) with alveolar recruitment maneuver with PEEP 15 cm H2O and afterwards 20 cm H2O remaining 2 minutes in each, then being maintained in NIV for 30 minutes with pressure support for a tidal volume of 6 ml/Kg, PEEP 8 cm H2O, Fraction of inspired oxygen for a peripheral arterial Saturation of Oxygen ≥ 95%.

After extubation the patient who was randomized to the Control Group will use noninvasive ventilation (NIV) for 30 minutes with pressure support for a tidal volume of 6ml/Kg, PEEP 8 cm H2O, Fraction of inspired oxygen for a peripheral arterial Saturation of Oxygen ≥ 95%.
