What is the difference between a primary blast secondary blast and tertiary blast?
Primary blast—unique to high-order explosives; results from the impact of the over-pressurization wave with body surfaces. Secondary blast—results from flying debris and bomb fragments. Tertiary blast—results from individuals being thrown by the blast wind.
What is a quaternary blast injury?
result from other explosive products (such as heat and light) and from exposure to toxic substances from fuels, metals, and gases that can cause burns, blindness, and inhalation injuries.
What is secondary blast injury?
Secondary blast injuries are caused by debris that is displaced by the blast wind of the explosion. The secondary blast injuries are caused by debris that penetrates or interacts with the body surface.
Is shrapnel a secondary injury?
Shrapnel wounds (secondary blast injury) are treated as low-velocity gunshot wounds.
What are the phases of blast injury?
The four basic mechanisms of blast injury are termed as primary, secondary, tertiary, and quaternary (Table 1).
What injuries are received during the primary blast phase?
Gas-containing sections of the GI tract are most vulnerable to primary blast effect. This can cause immediate bowel perforation, hemorrhage (ranging from small petechiae to large hematomas), mesenteric shear injuries, solid organ lacerations, and testicular rupture.
Which of the following is an example of primary brain injury?
Primary or immediate injuries include intracranial hemorrhage, intraparenchymal injuries, including DAI and contusions, cerebral edema, fractures, and extracranial soft-tissue injury/lacerations. Secondary injuries consist of hypoxia/ischemia, increased intracranial pressure, hydrocephalus, and infection.
What happens if you are near an explosion?
The main direct, primary effect to humans from an explosion is the sudden increase in pressure that occurs as a blast wave passes. It can cause injury to pressure- sensitive human organs, such as ears and lungs.
Does hearing come back after explosion?
A continuous blast injury usually leads to hearing loss in the high frequency range, which can be remedied effectively with hearing aids. The higher tones that are hard to hear can be perceived again.
What causes penetrating trauma caused by shrapnel?
Penetrating trauma caused by shrapnel is usually attributed to Primary blast effect.
Which is not a likely diagnosis for blast effect?
Terms in this set (157) A patient suffering blast effect presents with dyspnea, some hearing loss, and tinnitus following an explosion. Which of the following is NOT a likely diagnosis?
How is the victim of nerve agent exposure classified?
the most likely to occur, and will have the greatest impact on the greatest number of people. How is the victim of nerve agent exposure presenting with convulsions classified? Immediate Eyes are the most vulnerable to this agent due to their thin, moist, warm mucosa.
