How do you treat a patient with a flail chest?

• A. Intubate and provide PPV.
• B. Wrap the chest with bandage only.
• C. Apply external chest compressions.
• D. Press the segment during exhalation and wrap with bandage; intubate and PPV.

Answer: (D)

Stabilizing the loose segment of the chest wall to stop paradoxical movement and support breathing is the key idea. A flail chest lets a portion of the chest wall move independently, which severely increases work of breathing and impairs ventilation. The most effective approach combines external stabilization with definitive airway management and ventilation.

In practice, you temporarily stabilize the flail segment—often by pressing on it during the respiratory cycle to reduce abnormal movement and applying a supportive bandage or dressing to hold the segment in place. At the same time, securing the airway and providing positive-pressure ventilation helps re-expand the injured lung and acts as an internal splint for the chest wall, improving oxygenation and decreasing respiratory effort.

Other options don’t address both parts: simply providing a wrap or attempting chest compressions doesn’t correct the chest-wall instability or improve ventilation, and intubation with ventilation alone lacks the external stabilization that can reduce the paradoxical movement. The combined approach of external stabilization plus airway management and PPV best supports gas exchange and chest-wall mechanics in a flail chest.
