A patient with blunt chest trauma, RR 6, reduced tidal volume, cyanosis, and hypotension (80/50) should

• A. Wait and monitor
• B. Provide some form of positive-pressure ventilation
• C. Give high-flow oxygen and observe
• D. Perform rapid sequence intubation

Answer: (B)

In this scenario the patient is in respiratory failure from blunt chest trauma: breathing is severely inadequate (very low respiratory rate and small tidal volume) and they are cyanotic with low blood pressure. The most urgent need is to restore ventilation and oxygenation. Providing positive-pressure ventilation—such as with a bag-valve mask delivering high-flow oxygen—directly increases the amount of air reaching the lungs each breath, improves gas exchange, and raises oxygen delivery to tissues. That brief, active support stabilizes the patient now while you prepare for definitive airway management or continue other trauma care.

Waiting and monitoring would miss the life-threatening hypoventilation. Giving oxygen and observing alone won’t correct the inadequate ventilation. Rapid sequence intubation could be necessary, but the immediate priority is to improve ventilation first; RSI is more invasive and carries its own risks in a hypotensive, trauma patient, and may not be immediately feasible in the field.
