Correct answer: C — Support ventilation and request critical care support for flail chest with respiratory failure
Flail chest with hypoxaemia requires oxygenation, analgesia, ventilatory support and early critical care input. Tight circumferential binding impairs ventilation and is not recommended. Chest decompression is reserved for suspected tension pneumothorax with severe compromise. The pearl is that flail chest is a marker of high-energy injury and can deteriorate from pain, contusion and fatigue.
