Moderate to Severe TBI
Blast injuries are one of the most common causes of traumatic brain injury on the battlefield today. Blast injuries are caused by the impact from a complex pressure wave generated by an explosion. The explosion causes an instant rise in pressure, which creates a blast wave. This wave starts at the site of the explosion and travels outward.
Blast injuries can occur when the blast wave hits the body. Air-filled organs, such as the ears, lungs, stomach, and intestines are particularly at risk for blast injuries. This is also true for organs that are surrounded by fluid, such as the brain and the spine.
Other causes of brain injuries in a blast can include being hit by flying debris, being physically thrown, or breathing toxic gases or vapors.
