Study Arms:
- PRONE POSITION (Type: ACTIVE_COMPARATOR): Patients who require supplemental oxygen through a non-invasive device (nasal cannulas or reservoir mask) in the prone position.
- STANDARD TREATMENT (Type: PLACEBO_COMPARATOR): Patients who require supplemental oxygen through a non-invasive device (nasal cannulas or reservoir mask) in the supine position with the head of the bed between 30-60º.

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