In cases of significant chest injury accompanied by visible respiratory distress, the primary concern is often a pulmonary contusion. A pulmonary contusion is a bruise of the lung tissue that can cause bleeding and swelling within the lungs, leading to impaired gas exchange and respiratory distress. This can be critically serious, as it directly affects the patient's ability to oxygenate their blood, which is vital for survival.

When assessing a patient with a significant chest injury, recognizing that a pulmonary contusion can develop as a result of blunt trauma is essential. The presence of respiratory distress indicates that the lungs may be compromised, and addressing the underlying issue, such as managing a pulmonary contusion, is crucial for stabilizing the patient.

While airway obstruction is indeed a potential concern in chest injuries, and external bleeding may also be present, the direct impact of lung injury on oxygenation and ventilation makes pulmonary contusion the foremost priority to address. Flail chest, while also a serious condition that can lead to respiratory compromise, primarily involves the structural integrity of the rib cage rather than direct lung tissue damage. Thus, the urgent concern here revolves around the likelihood of pulmonary contusion causing significant respiratory impairment.
