Study Arms:
- Esophageal balloon catheter placement (Type: None): This is the primary and only arm of the study in which acute respiratory distress syndrome patients will have an esophageal balloon catheter placed with pressures recorded in the supine, upright and prone positions

Based on this trial design, predict the completion outcome and termination type (if applicable).
