Trial Title: Efficacy of Non-Invasive Mechanical Ventilation in Early Hypoxia Secondary to Thoracic Trauma

Study Design Characteristics:
- Allocation: RANDOMIZED
- Intervention Model: PARALLEL
- Observational Model: None
- Primary Purpose: PREVENTION
- Time Perspective: None
- Masking: NONE
- Phase: PHASE4
- Number of Arms: 2.0

Eligibility Criteria:
Inclusion Criteria:~* Age \> 18 years.~* Informed consent obtained.~* pO2/FiO2 \<200 for more than 8 consecutive hours in the first 48 hours after thoracic trauma.~Exclusion Criteria:~* Orotracheal intubation indicated for any other reason.~* Standard contraindication for non-invasive ventilation (active gastro-intestinal haemorrhage, low level of consciousness, multiorgan failure, airway control problems, lack of cooperation, hemodynamic instability).~* Severe traumatic brain injury.~* Facial trauma with pneumocephalus, skull base fracture, orbit base fracture, any facial fracture involving a sinus.~* Cervical injury with specific treatment contraindicating a facial mask.~* Bronco-pleural fistula.~* Gastro-intestinal trauma.

- Gender: ALL
- Minimum Age: 18 Years
- Maximum Age: None
- Healthy Volunteers: f

Study Arms:
- 1 (Type: ACTIVE_COMPARATOR): Addition to the standard therapy of non-invasive mechanical ventilation. Continuously for the first 24 hours, then trials to discontinuation every 24 hours. Interface adjusted for the associated injuries.
- 2 (Type: NO_INTERVENTION): Standard therapy for severe post-traumatic hypoxia: pain control with epidural anesthesia and oxygen.

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