|Condition or disease||Intervention/treatment||Phase|
|Acute Respiratory Failure Requiring Reintubation||Procedure: Helmet CPAP Procedure: Venturi Mask||Not Applicable|
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.

|Masking:||None (Open Label)|
|Official Title:||CPAP Reduces Hypoxemia After Cardiac Surgery (CRHACS Trial). A Randomized Controlled Trial|
|Study Start Date :||April 2013|
|Estimated Primary Completion Date :||September 2017|
|Estimated Study Completion Date :||November 2017|
Procedure: Helmet CPAP
the patient will receive CPAP treatment, at a PEEP level of 10 cmH2O and a FiO2 adjusted to maintain SpO2>95%, for six hours. After three hours of treatment a blood gas analysis will be evaluated and the patient will proceed with the treatment for three more hours. At the end of the six hours, the patient will repeat a spontaneous breathing trial with a Venturi mask at FiO2 = 50%, for 15 minutes and than a blood gas analysis will be repeated: if the PaO2/FiO2 will be < 200 the patient will received a second treatment with CPAP; if PaO2/FiO2 will be >200, the patient will stop the treatment.
Active Comparator: CONTROL
Procedure: Venturi Mask
the patient will maintain spontaneous breathing, with a system for oxygen delivery at a FiO2 adjusted to maintain SpO2>95%, for six hours. After three hours of treatment a blood gas analysis will be evaluated and the patient will proceed with the treatment for three more hours. At the end of the six hours, the patient will do a trial for 15 minutes and after that a blood gas analysis will be repeated: if the PaO2/FiO2 will be < 200 the patient will go on with the control treatment; if PaO2 /FiO2 will be >200, the patient will stop the treatment.
