A New Ultrasonographic Tool to Assess Pulmonary Strain in the ICU
Trial Parameters
Brief Summary
The primary objective of the study is to create a small dataset of regional pulmonary strain values in patients suffering from pulmonary diseases under mechanical ventilation in an intensive care setting. Hypothesis: The analysis of lung ultrasonographic sequences using speckle-tracking allows the determination of local pleural strain in 4 predetermined pulmonary areas in mechanically ventilated patients suffering from pulmonary diseases.
Eligibility Criteria
Inclusion Criteria: * Adult intensive care patients under mechanical ventilation suffering from a pulmonary disease with a static lung compliance of less than 40 mL/cm H2O. Exclusion Criteria: * Obesity (Body Mass Index superior to 30 kg/m2) * Previous thoracic procedure (chest tube, thoracotomy, thoracoscopy) * Intra-abdominal pressure inferior to 15 mm Hg (if available) * Previous participation to the study
