Study Overview
Brief Summary
Esophageal pressure measurements are used in moderate/severe Accurate Respiratory Distress SyndromeARDS patients in order to set ventilator settings. There might be variations of the measured value according to the patient position (0° vs 30°) at the time of measurements.

Arms & Interventions
head-bed position
Head-bed position at 0° for 30 minutes then head-bed position at 30° for 30 minutes
Intervention: head-bed position (Other)
Outcomes
Primary Outcomes
Total End-expiratory esophageal pressure
Time Frame: 30min after change of position
After end-expiratory pause on the ventilator, absolute value of the esophageal pressure is measured (in Head-bed position at 30° then in head-bed position at 0° )
Secondary Outcomes
- End-expiratory lung volume(30min after change of position)
- End-inspiratory esophageal pressure(30min after change of position)
- Gastric pressure(30min after change of position)
