PEEP Test and Gas Exchange in ALI/ARDS Patients
The investigators aim to study the effect of different levels of PEEP in ALI/ARDS patients on gas exchange.
|Study Design:||Allocation: Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
|Official Title:||Positive End Expiratory Pressure (PEEP) Test and Gas Exchange in ALI/ARDS Patients|
- Gas exchange, dead space, respiratory mechanics [ Time Frame: 5, 15, 30, 60 minutes from PEEP change ] [ Designated as safety issue: No ]
|Study Start Date:||January 2006|
|Study Completion Date:||April 2008|
|Primary Completion Date:||April 2008 (Final data collection date for primary outcome measure)|
Procedure: Mechanical ventilation
measurement of gas exchange, dead space, respiratory mechanics 5, 15, 30, 60 minutes from PEEP change (5 and 15 cmH2O)
In a population of ALI/ARDS patients during mechanical ventilation we will evaluate the effect of different levels of PEEP on gas exchange and dead space.
