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

This study has been terminated.
(The study was prematurely interrupted because patients randomized to CPAP reached the endpoint quicker than anticipated in the protocol)

Primary Outcome Measures:
  • 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 ]

Arms Assigned Interventions
Active Comparator: 1
CPAP delivered by a helmet
Procedure: Castar Starmed (CPAP) delivered by a helmet
Continuous Positive Airway Pressure delivered by a helmet with PEEP valve of 10 cmH2O and FiO2 0.5
Other Name: Castar Starmed CP209/2
No Intervention: 2
O2 administration via a conventional Venturi mask

Detailed Description:

Community-acquired pneumonia (CAP) is one of the commonest causes of hospitalised acute respiratory failure with a mortality rate up t 30%.

Continuous Positive Airway Pressure (CPAP) has ben recently proved to be effective. To date, however, no prospective randomised study has been published on the comparison between CPAP and O2 administration via a Venturi mask for the treatment of acute respiratory failure in immunocompetent patients with community-acquired pneumonia.

Therefore, the aim of this study is to compare the efficacy of CPAP delivered by a helmet and O2 administration via a Venturi mask in terms of gas exchanges improvement in early acute respiratory failure (PaO2/FiO2 between 210 and 285)due to community-acquired pneumonia.

A Steering Committee composed by the principal investigators will request an interim analysis at 20% enrolment in order to monitor the criteria for equipoise of the two treatments.
