In blast injuries, primary blast injuries are most likely to affect which organs?

Primary blast injuries come from the blast overpressure itself, not from flying debris. The organs most affected are gas-filled structures because the rapid pressure spike directly stresses air-filled spaces. The lungs are particularly vulnerable to pulmonary barotrauma, which can cause alveolar rupture, contusions, pneumothorax, and edema. The ears are also commonly damaged, with tympanic membrane rupture being a classic sign of a significant blast. Other organs like the liver or bones are less likely to sustain primary blast injury because they’re not air-filled and are more often affected by secondary (shrapnel) or tertiary (body displacement) mechanisms. So, the combination of the lungs and ears is the most characteristic target of primary blast injuries.
