Blunt Trauma

A body in motion will stay in motion unless acted upon by an outside force. Inertia.
Energy can neither be created nor destroyed. It is only changed from one form to another. Conservation of energy.
Energy in motion. Double weight =double energy. Speed is the greatest factor! Kinetic energy.
Emphasizes the importance of rate at which an object changes speed. (Acceleration or deceleration) Force.
Indirect injury to underlying structures, transmission of energy into the body, tearing muscles, vessels and bone, rupture of solid organs. Closed injury.
Open injury. Direct injury to underlying structures. Penetrating.
Events of impact in mvc. Vehicle collision. Body collision. Organ collision. Secondary collision (objects inside vehicle strike occupant)
Reduce blunt chest trauma but causes hand, forearm and facial injuries. Airbags.
Events of an explosion. Pressure wave. Structure collapse. Blast wind. Burns. Projectiles. Personal displacement.
Blast injury phases. Primary-heat of explosion. Secondary-trauma caused by projectiles. Tertiary-personal displacement and structure collapse.
Blast injuries Ruptured organs. Hearing loss. Lungs. Diaphragm rupture. Penetrating wounds. Burns.
Crush injuries Damage caused by great force to soft tissue and bones. Tissue stretching and compression. Extended pressure results in anaerobic metabolism distal to compression. Toxins build. Hemorrhage.
Care for prolonged crush injuries. Sodium bicarb-reduces acidosis. Dopamine-improve kidney function. Morphine-pain management. Longer than 45 mins, push bicarb and calcium before release.
