Number of deaths a year from penetrating trauma?
3 levels of Penetrating Trauma?
- Low: Bladed&pointed,knives,swords,darts,ski poles
- Med: Handguns & Shotguns (200-400 meter per sec)
- High: Rifle (600-900 meters per sec)
formula for KINETIC ENERGY
kinetic energy= MASS(wt) X Velocity(speed)2÷2
Relationship of VELOCITY to ENERGY is
LAW OF CONSERTIVE ENERGY is
Energy can be neither created NOR destroyed,only changed from one form to another
force=Mass X Acceleration (or Deceleration)
Study of Projecticles in motion and their effect on objects they impact is
The curve path of a projectile leaving an item being pulled down by gravity is
The resistance force acting on a projectile in motion to slow its progress is called
The portion of the semifluid body tissue in motion, creating a shockwave and a temporal cavity is called
The portion of the bullet you would see if you looked at it as it traveled straight to you is called
lift created by the projectiles tip passing through the air causes it to wait?
A high velocity projectile inflicts a damage pathway related to 3 injury processes. They are
- direct injury
- pressure wave
- cavitation (temporary cavity)
- can also cause permanent cavity & zone of injury
the diameter of a bullet expressed in hundredths of an inch; the inside diameter of the barrel of a handgun or rifle is known as
nonsurgical procedure resulting in perforation of the membrane between the thyroid and cricoid cartillages and insertion of a needle or commercial cricothyrotomy device to provide an emergency airway is known as
A restriction to cardiac filling caused by blood (or other fluid) within the pericardial sac.
An object hurled or projected by the exertion of force is an
elasticity; the ability to spring back from a force or impact to resume the original condition is also called
swing or wobble around the axis of a projectiles travel is
In association with projectile wounds, the maximum are of injured tissue, usually extend beyond the permanent cavity formed by the projectile is the______
