The main concept is recognizing injuries caused by the blast overpressure that occur early after exposure—primary blast injuries. The most characteristic early findings are from the pressure wave acting on air-filled organs. The tympanic membrane is very susceptible to sudden pressure change, so rupture or perforation is a classic early sign. The lungs are also vulnerable to overpressure, leading to pulmonary barotrauma, which can present with chest pain, shortness of breath, coughing, blood in the spit, or even pneumothorax. These injuries can occur even when external wounds are minimal, so they’re essential to assess promptly after a blast.

Shrapnel injuries are a real concern in blast scenarios because debris can cause penetrating wounds, but those are secondary injuries caused by flying objects, not by the overpressure wave itself. The other listed possibilities—thermal burns, spinal injuries from shifting or being struck, or allergic reactions—are not the primary early injuries caused by the blast overpressure and are less likely to be the first injuries to watch for.
