No one is certain what really causes primary explosive blast traumatic brain injury (bTBI), according to New York Brain Injury Lawyers. Clearly, the “cause” is the explosion and the mechanism by which it works is the interaction of explosive force upon the human body, but this does not medically explain everything that occurs.
There are primary and secondary injury mechanisms when it comes to trauma. Primary injury mechanisms can be attributed directly to the cause of the injury, like laceration from a cut. Secondary injuries are physiological responses, like bleeding or bruising. When it comes to bTBI, there is probably more than one primary injury mechanism involved.
The blast produced by an explosive device travels through a medium like air or water in a wave of pressure. Basically, a great deal of energy is chemically produced. Mechanical, thermal, and electromagnetic energy is transferred into the surrounding medium, and into anyone who happens to be in the blast radius.
