Summary
Brief summary (as posted)
Besides protective ventilation with low tidal volumes, prone positioning is a proven intervention to decrease mortality in mechanically ventilated patients with moderate-severe acute respiratory distress syndrome. However, the evidence of this strategy in awake non-intubated patients is scarce. The investigators will perform a randomized controlled trial to define if prone positioning can reduce the requirement of mechanical ventilation.

- Standard oxygen therapy
- description
- Oxygen therapy through high flow nasal cannula (HFNC). Continuous monitoring of vital signs. Inspired fraction of oxygen will be titrated to maintain a capillary saturation of ≥92%. Prone positioning will be allowed as a rescue therapy.

- Procedure: Standard oxygen therapy
- type
- EXPERIMENTAL
- label
- Awake prone positioning
- description
- Oxygen therapy through high flow nasal cannula (HFNC). Patients will be asked to remain in prone position throughout the day as long as possible, with breaks according to tolerance. Pillows will be offered for maximizing comfort at chest, pelvis and knees. Monitoring of vital signs will not be suspended. Inspired fraction of oxygen will be titrated to maintain a capillary saturation of ≥92%.
