We want to test the hypothesis that the application of a continuous positive airway pressure (CPAP) after extubation in patients undergoing cardiac surgery can reduce hypoxemia and re-intubation rate.~Primary end point: to reduce the rate of re-intubation.~Secondary end point: to reduce the incidence of atelectasis, pneumonia, sepsis, the mortality rate, the intensive care unit (ICU) and hospital length of stay.
The aim of study is to evaluate whether the application of a continuous positive airway pressure (CPAP) after extubation in patients undergoing cardiac surgery can reduce hypoxemia and re-intubation rate.
