Evaluation of the Lung Recruitment and End-expiratory Lung Collapse in Acute Respiratory Distress Syndrome (ARDS)

This study has been completed.

Davide Chiumello, Policlinico Hospital Identifier:
First received: August 14, 2012
Last updated: March 18, 2015
Last verified: March 2015
In this study gas-exchange and respiratory mechanics variations to PEEP change will be correlated to CT lung morphological modifications assessed at different airway pressures (5, 15, 30 and 45 cmH2O).

Condition Intervention
ARDS: Acute Respiratory Distress Syndrome Radiation: Chest computed tomography

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: Evaluation of the Lung Recruitment and End-expiratory Lung Collapse in Patients With Acute Respiratory Distress Syndrome

Further study details as provided by Davide Chiumello, Policlinico Hospital:

Primary Outcome Measures:
  • Computer Tomography (CT) scan lung recruitment and CT lung weight [ Time Frame: Study day (day 1) ]
    Aim of the study is to determine the relationship between the opening pressures (recruitment) and closing pressures (PEEP) in order to prevent the opening and closing of the lung parenchyma

Estimated Enrollment: 30
Study Start Date: September 2012
