Explosions have the capability to cause multisystem, life-threatening injuries in single or multiple victims simultaneously. Explosions can produce classic injury patterns from blunt and penetrating mechanisms to several organ systems, but they can also result in unique injury patterns to specific organs including the lungs and the central nervous system CNS. The extent and pattern of injuries produced by an explosion are a direct result of several factors including the amount and composition of the explosive material (eg, the presence of shrapnel or loose material that can be propelled, radiological or biological contamination). The closer a casualty is to an explosion, the more likely he will receive primary blast injury (PBI) from the effects of blast overpressure alone, particularly if behind cover and shielded from ballistic trauma.
