In blast injury management, damage to which organ is a key indicator of blast lung involvement during examination?

• A. Heart
• B. Kidneys
• C. Lungs
• D. Brain

Answer: (C)

Primary blast effects on air-filled organs explain why the lungs are the organ most closely linked to blast lung involvement. The overpressure wave directly affects the lungs, making pulmonary contusion, edema, and air leaks the hallmark injuries. In examination, look for signs of respiratory compromise that point to lung injury: rapid or labored breathing, hypoxia or low oxygen saturation, diminished or abnormal breath sounds, chest pain, coughing up blood, or signs of chest wall injury such as subcutaneous emphysema. Those pulmonary findings are the strongest indicators of blast lung involvement. Damage to the heart, kidneys, or brain can occur in blasts, but they do not specifically indicate lung injury in the exam.
