Q

Level one regional trauma center

What kind of cases can they manage?

A
  • All types of trauma 24/7
19
Q

Level two area trauma center

What cases can they manage?

A
  • Can manage a vast majority of trauma and surgical capabilities
  • Can stabalize trauma patients before transfering them to a level 1 trauma center
20
Q

Level three Community trauma center

What cases can they manage

A
  • Some surgical capabilities but not really what they do
  • they manage the trauma and stabalize serious injuries before transfering them to a higher level center
21
Q

Level four trauma facility

What cases can they handle?

A
  • Typically a small community hospital in a remote area capable of stabalizing seriously injured trauma patients and then transferring to a higher level center
22
Q

4 key factors for high velocity (bullets) injuries

A
  • Drag
  • Profile
  • Cavitation
  • Fragmentation
23
Q

Drag

Define

A
  • the factors that slow a bullet down such as wind resistance
24
Q

Profile

Define

A
  • The impact point of the bullet is its profile. The greater the size of the impact point the more energy is transferred
25
Q

Cavitation

Define

A
  • How big is the hole in the body
26
Q

Fragmentation

Define

A
  • A bullet that breaks up into small pieces or releases small pieces upon impact creating a larger injured area
