Blast wave injuries

Blast injuries can result from various types of incidents ranging from industrial accidents to deliberate attacks. High-order explosives produce a supersonic overpressure shock wave, while low order explosives deflagrate and do not produce an overpressure wave. A blast wave generated by an explosion starts with a single pulse of increased air pressure, lasting a few milliseconds. The negative pressure (suction) of the blast wave follows immediately after the positive wave. The d… WebPrimary blast injury The blast wave causes primary blast injuries such as blast lung. In this fatal case both lungs have hemorrhaged. There were barely any external signs of injury, death was due solely to internal injuries from the blast wave. Blast lung is the most common fatal primary blast injury in people who survive the initial explosion.
