Helmet Continuous Positive Airway Pressure Versus Oxygen Venturi in Acute Respiratory Failure in CAP: CAPOVeRSO (CAPOVeRSO)

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00603564
Recruitment Status : Terminated (The study was prematurely interrupted because patients randomized to CPAP reached the endpoint quicker than anticipated in the protocol)

Recruitment Details
Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
The Steering Committee requested an interim analysis at 20% enrollment in order to monitor the criteria for actual equipoise of the two treatments. Being this unplanned, the Lan-DeMets approach was followed and a manifest superiority of the CPAP treatment was identified, with a nominal alpha exceeding the criterion for interruption set at 0.00008.

  Outcome Measures

1.  Primary:   Time to Reach an Improvement in Terms of Gas Exchange, Defined as a PaO2/FiO2 Ratio ≥315   [ Time Frame: on admission and at 1, 6, 12, 24 and 48 hours until PaO2/FiO2 ratio ≥315 ]

2.  Secondary:   PaO2/FiO2 Ratio Mantainance   [ Time Frame: 1, 6, 12, 24 and 48 hours ]

  Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
Limitations of our study are mainly related to the early reaching of the end-point of the CPAP group. We were not able to evaluate the safety of the CPAP application and to address conclusions on its efficacy on outcomes.
