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

This study is currently recruiting participants. (see Contacts and Locations)

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 Policlinico Hospital:

Primary Outcome Measures:
  • Computer Tomography (CT) scan lung recruitment and CT lung weight [ Time Frame: Study day (day 1) ] [ Designated as safety issue: No ]
    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
Estimated Study Completion Date: May 2014
Estimated Primary Completion Date: May 2014 (Final data collection date for primary outcome measure)
