Pressure compresses organs (Air filled and fluid filled most impacted)factors influencing severity:- peak pressure of the initial blast wave- duration of blast wave- environment in which the explosion occurs (confined pace or open area)- distance from the source of the explosion- secondary injuries sustained due to flying shrapnel and other objects- tertiary injuries sustained when the body being physically thrown from blast TERM 7 penetrating head injury DEFINITION 7 - anytime an object breaks through the skull and enters the brain- survival rate is 10% TERM 8 what what is really happening in the brain after impact? DEFINITION 8 Coup-Contrecoup Injury Rotational forces Diffuse Axonal Injury (DAI) Sheering injury Edema Neurometabolic cascade Neurotransmitter Dysfunction Process similar to Migraine? TERM 9 coup contrecoup injury (linear forces) DEFINITION 9 Injury to two opposite sides of the brain. One in the direction of the momentum One in the opposite direction Injury is often frontal and occipital But can occur in any direction depending on the direction of the momentum Additionally, the brain compresses contributing to Diffuse Axonal Injury TERM 10 bony projections DEFINITION 10 boney projections on the inside of the skull contribute to risk of- contusions- hematomas
