Jason PY - 2021 T2 - The Atlas of Emergency Medicine, 5e AB - A flail chest occurs when segmental rib fractures allow a section of the thoracic cage to move independently. The negative inspiratory pressure created by the diaphragm is less effective since the flail segment paradoxically moves inward and interferes with ventilation. Pulmonary contusion, hemothorax, pneumothorax, and great vessel injuries frequently accompany a flail chest.
