What organs are affected by a primary blast injury?

What organs are affected by a primary blast injury?

Primary Blast Injury 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.

What are the most common injuries from a blast?

The most common primary blast injuries include:

• blast lung—pulmonary barotraumas.
• head—traumatic brain injury (TBI), concussion.
• ear—tympanic membrane (eardrum) rupture.
• ear—middle ear damage.
• abdomen—hemorrhage.
• abdomen—organ perforation.

What causes secondary blast injury?

A secondary blast injury is caused by flying objects that strike people. A tertiary blast injury is a feature of high-energy explosions. This type of injury occurs when people fly through the air and strike other objects.

What is a quaternary blast injury?

Quaternary blast injury refers to all blast-related injuries not encompassed in the first three types listed above. These include burns, toxic gas inhalation, smoke inhalation, crush injuries and exacerbation of pre-existing medical conditions.

What are the main effects of explosions?

Explosion effects generally include those of overpressure, thermal effects, energized projectiles (fragments, debris, and missiles), ground shock, and cratering.

What causes an explosion?

An explosion is a rapid expansion of gases. Many explosions occur when gases are exposed to a source of heat- such as fire, sparks, even static elec- tricity-or an increase in pressure. Explosions can also be caused by chemical reactions. Some chemicals can even explode if exposed to air or water.

What are the main effects of 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.

What are the different types of explosions?

There are three main types of explosions: chemical, mechanical and nuclear. Each type of explosion can be equally devastating and serious, causing unprecedented harm to the surrounding people, atmosphere and infrastructure.

What are the causes of gas explosion?

Gas explosions can occur for a number of reasons including faulty appliances or equipment, a leak, or improper usage of a gas appliance. Gases are chemical substances, that when kept in an unstable environment or are exposed to an ignition source such as heat or fire, have to potential to explode.
