A patient shows respiratory distress after a sudden blast. Which organ is most likely involved given the overpressure exposure?

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

Answer: (D)

When a blast delivers a sudden overpressure, the primary impact tends to hit gas-filled organs hardest. The lungs are especially vulnerable because the rapid compression and expansion of air within the alveoli can cause alveolar rupture and damage to pulmonary vessels. This leads to pneumothorax, pulmonary contusion, edema, and impaired gas exchange, which manifest as respiratory distress right after the blast. While other organs can be injured by blast forces, the immediate breathing difficulty after overpressure most strongly points to lung injury.
