  Purpose

The purpose of this study is to determine the effects of variable ventilation on respiratory system of patients affected by acute respiratory distress syndrome.


Condition Intervention
ARDS
 Procedure: Variable ventilation

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Endpoint Classification: Efficacy Study
Intervention Model: Single Group Assignment
Masking: Single Blind (Investigator)
Primary Purpose: Treatment
Official Title: Effects of Variable Ventilation on Respiratory System of ARDS Patients

Further study details as provided by Policlinico Hospital:

Primary Outcome Measures:
  • Gas exchange and respiratory mechanics [ Time Frame: within the first 60 minutes from the ventilatory change ] [ Designated as safety issue: No ]

Estimated Enrollment: 16
Study Start Date: March 2005
Estimated Study Completion Date: December 2012
Primary Completion Date: March 2010 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1
ALI/ARDS patients
 Procedure: Variable ventilation
Patients will be mechanically ventilated with Variable Ventilation (3 step with increased level of variability) and "traditional" CMV, for a total of 4 step. Each step lasts in 60 minutes. During this period the investigators will record the gas exchange parameters and the mechanics of the respiratory system.

Detailed Description:

In this interventional study we want to evaluate the effect of Variable ventilation (1) in patients with ARDS. Patients will be mechanically ventilated with Variable Ventilation (3 step with increased level of variability) and "traditional" CMV, for a total of 4 step. Each step lasts in 60 minutes. During this period we will record the gas exchange parameters and the mechanics of the respiratory system.
