Blast injury - Wikipedia
Blast injuries occur with the detonation of high-order explosives as well as the deflagration of low order explosives. These injuries are compounded when the explosion occurs in a confined space. Blast injuries are divided into four classes: primary, secondary, tertiary, and quaternary.

Sep 12, 2024 · A blast wave is an area of pressure expanding supersonically outward from an explosive core. It has a leading shock front of compressed gases. The blast wave is followed by a blast wind of negative pressure, which sucks items back in towards the center.

Jul 17, 2023 · Since only high order explosives create a blast wave, primary blast injuries are unique to high order explosions. The blast wave causes damage to more extensively to air-filled organs. The resulting barotrauma can affect the lungs, auditory organs, the eye, brain, and gastrointestinal tract.
Pathophysiology of Blast Injury and Overview of Experimental …
Apr 14, 2014 · The blast wave is the main determinant of the primary blast injury and consists of the front of high pressure that compresses the surrounding air and falls rapidly to negative pressure. It travels faster than sound and in few milliseconds damages the surrounding structures.

Primary blast wave increased in closed space - detonation in corner has potential to increase blast yield to 8x; Recent enhanced-blast weapons (EBW) disperses gas before explosion - larger blast wave with lower pressure amplitude that diffuses around corners; Spalling Effect
Blast lung is the most common fatal injury among initial survivors. Explosions in confined spaces (mines, buildings, or large vehicles) and/or structural collapse are associated with greater morbidity and mortality. Half of all initial casualties will seek medical care over a one-hour period.

The supersonic blast wave in primary blast injury compresses gas-filled spaces, which then rapidly reexpand, causing shearing and tearing forces that can damage tissue and perforate organs. Blood is forced from the vasculature into air spaces and surrounding tissue.
Primary: Injury from over-pressurization force (blast wave) impacting the body surface — TM rupture, pulmonary damage and air embolization, hollow viscus injury. Secondary: Injury from projectiles (bomb fragments, flying debris) — Penetrating trauma, fragmentation injuries, blunt …
