Primary injuries are caused by blast overpressure waves, or shock waves. Total body disruption is the most severe and invariably fatal primary injury. [2] Primary injuries are especially likely when a person is close to an exploding munition, such as a land mine. [3]
Blast overpressure (BOP), also known as high energy impulse noise, is a damaging outcome of explosive detonations and firing of weapons. Exposure to BOP shock waves alone results in injury predominantly to the hollow organ systems such as auditory, respiratory, and gastrointestinal systems.
Soldiers will also be directed to stay as far away as possible from blasts during training exercises and operations to reduce exposure to blast overpressure and limit potential damage, according ...
The Defense Department does not have good data on the number of troops with blast overpressure problems, which are much harder to detect than a traumatic brain injury. Traumatic brain injuries are better known and have been a persistent problem among combat forces, including those subjected to missile strikes and explosions that hit nearby.
Initial stage—the first 1–9 weeks, in which are the greatest number of deaths, with 90% due to thermal injury and/or blast effects and 10% due to super-lethal radiation exposure. Intermediate stage—from 10 to 12 weeks. The deaths in this period are from ionizing radiation in the median lethal range - LD50; Late period—lasting from 13 to ...
Symptoms of traumatic brain injury include persistent headaches or neck pain, fatigue, memory issues, trouble sleeping, concentration problems, chronic depression, anxiety and apathy, researchers say.
Emerging information from evaluations of both acute blasts and repetitive low-level exposures are linked to adverse effects, such as the inability to sleep, degraded cognitive performance, headaches and dizziness, and the Defense Department is committed to understanding, preventing, diagnosing and treating blast overpressure “and its effects ...
The U.S. Defense Department is going to require cognitive assessments for all new recruits as part of a broader effort to protect troops from brain injuries resulting from exposure to blasts ...
