Blast injury - Wikipedia
There is general agreement that spalling, implosion, inertia, and pressure differentials are the main mechanisms involved in the pathogenesis of primary blast injuries.
In this analysis, we assume that a medium or large explosion, less than 1000 feet away, will likely kill or severely incapacitate the crew instantly and render the need for the refuge chamber moot. Such a scenario could occur at any working face, longwall or room-and-pillar.
Pathophysiology of Blast Injury and Overview of Experimental …
Apr 14, 2014 · Implosion occurs when the shock wave compresses a gas bubble in a liquid medium, raising the pressure in the bubble much higher than the shock pressure; as the pressure wave passes, the bubbles can re-expand explosively and damage surrounding tissue (Benzinger, 1950; Chiffelle, 1966; Phillips, 1986).
Blast injury - WikEM
Due to blast pressure forces, injuries are to organs with air-fluid interfaces (spalling effect) CXR with large right sided hemothorax (and widened mediastinum).
Understanding blast-induced neurotrauma: how far have we come?
Blast injuries, including blast-induced neurotrauma (BINT), are caused by blast waves generated during an explosion. Accordingly, their history coincides with that of explosives.
Blast Injuries and Blast-Induced Neurotrauma - Brain …
Spallation occurs at the boundary between two media of different densities when a compression wave in the denser medium is reflected at the interface. Implosion happens in a liquid medium containing a dissolved gas.
Blast Injuries | New England Journal of Medicine
Dec 11, 2024 · Blast injuries are a complex form of trauma, resulting from the explosive release of energy. This review focuses on the mechanisms and classifications of blast injuries and presents...
High risk and low prevalence diseases: Blast injuries
Aug 1, 2023 · Primary blast injuries typically result from three different physical mechanisms: spallation, implosion, and shearing injuries. Spallation occurs when the pressure blast wave passes from a dense medium to a less dense medium (e.g., bowel wall into the gas-filled bowel).
Explosions and blast injuries - Annals of Emergency Medicine
Feb 24, 2000 · Primary blast injury (PBI) occurs as a direct effect of changes in atmospheric pressure caused by a blast wave. Secondary blast injuries occur when objects accelerated by the energy of the explosion strike a victim, causing either blunt or penetrating ballistic trauma.
State of the Science: Blast Injury Pathophysiology
Jul 4, 2020 · Blast injuries are particularly complex, because blast effects are multimodal, with injury-causing overpressure, dynamic pressure, debris, and fragmentation. The organs most vulnerable to blast injury are those which are gas-containing, such as the ears and lungs.
