A Validation/Interventional Study on Stress Index in Predicting Mechanical Stress in ARDS Patients

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00465374
Recruitment Status : Unknown

Brief Summary:
30% of ARDS patients ventilated according to NIH protocol presents CT scan evidence of hyperinflation. Functional analysis of pressure-time curve (Stress Index=SI) has been shown to identify this condition in experimental settings. We tested the hypothesis that the SI is an accurate predictor of mechanical stress due to overdistention in ARDS patients.

Condition or disease Intervention/treatment Phase
Respiratory Distress Syndrome, Adult Procedure: Change ventilatory parameters with stress index monitoring Phase 3

Detailed Description:
The study presents two parts : a preliminary validation study and a clinical study.
