The risk of respiratory failure after cardiac surgery is high, and it may result in many complications. The maneuver of alveolar recruitment may improve the oxygen transport in the human organism. The investigators compare three different types of alveolar recruitment in patient after cardiac surgery, to reveal which one is better.
The study compares three different approaches to alveolar recruitment maneuvers in the immediate postoperative period after off-pump coronary bypass grafting.
