Brief Summary:
The aim of this study is to evaluate the performance, the tolerability and the efficacy on gas-exchange of different CPAP (Continuous Positive Airway Pressure) systems.

Condition or disease Intervention/treatment
Acute Respiratory Failure Procedure: CPAP system

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.

Study Type : Observational
Actual Enrollment : 30 participants
Observational Model: Cohort
Time Perspective: Prospective
Official Title: The CPAP in Patients Affected by Acute Respiratory Failure
Study Start Date : April 2009
Actual Primary Completion Date : January 2014
Actual Study Completion Date : January 2014

Group/Cohort Intervention/treatment
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

Primary Outcome Measures :
  1. Respiratory mechanics, work of breathing, end-expiratory lung volume (EELV) and gas exchange [ Time Frame: 30 minutes ]

Secondary Outcome Measures :
  1. Comfort of breathing [ Time Frame: 30 minutes ]
