This leads to paradoxical chest wall movement during respiration, which impairs effective ventilation. The most significant concern is the associated pulmonary contusion. Management focuses on pain control, pulmonary hygiene, and supportive care, with mechanical ventilation reserved for those with respiratory failure.
