High Flow Nasal Cannula vs Noninvasive Ventilation in Patients With Hypoxic Respiratory Failure Following Blunt Chest Trauma

High Flow Nasal Cannula vs Noninvasive Ventilation in Patients With Hypoxic Respiratory Failure Following Blunt Chest Trauma, a Randomized Clinical Trial

to compare high flow nasal cannula against noninvasive ventilation in patients with non-sever blunt chest trauma in improvement of oxygenation, need for intubation and mechanical ventilation within 28 days

Inclusion Criteria:

• Age ≥18 y,
• Willing and able to provide written informed consent prior to performing study procedures,
• currently hospitalized and requiring medical care for non-sever blunt chest trauma (abbreviated injury severity scale ≤ 2) SpO2 90% or less while breathing 10 L/min.

Exclusion Criteria:

• Contraindications of noninvasive ventilation (face trauma or surgery, airway obstruction, upper gastrointestinal tract bleeding, disturbed level of consciousness), -smoker
• intubation for any cause other than respiratory cause
