Primary Completion Date: January 2014 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Acute Respiratory Failure patients
Procedure: CPAP system

Evaluating the effects of different CPAP systems on respiratory mechanics, respiratory effort and gas-exchange

CPAP systems:

Continuous high-flow CPAP with fixed value PEEP valve

Continuous high-flow CPAP with Boussignac valve

Demand flow CPAP supplied by ventilator

Detailed Description:
Three CPAP systems are studied for each patient at the same level of PEEP: 1) continuous high-flow CPAP with fixed value PEEP valve; 2) continuous high-flow CPAP with Boussignac PEEP valve; 3) demand flow CPAP, supplied by a ventilator.
