Conditions
Brief summary
The Electrical Impedance Tomography (EIT) is a non-invasive exam. This exam performed on the lung continuously produces cross-sectional images of lung function. It may be relevant in lung description.
Detailed description
The aim is to follow the patients after extubation for the lung description. EIT exam is performed before extubation, during follow-up visits and 48H after extubation
Interventions
DEVICEEIT
Electrical Impedance Tomography is performed before extubation, during follow-up visits of extubation and 48H after extubation. Follow-up visits are shortened in case of extubation failure.
