Which of the following BEST explains why positive pressure ventilation is the correct management step for a patient with flail segment?

B) The positive pressure accentuates movement of the thorax inward, reducing the movement of the fracture site and moving the flail segment with the chest. C) The positive pressure permanently inflates the flail segment in order to maximize oxygenation. D) The positive pressure displaces the thorax outward, reducing the movement of the fracture site and moving the flail segment with the chest.
