CSB337 Exam Revision
Mechanism of injury - ANS-The way in which an injury was sustained
- RTC
- Fall
- Blunt trauma
- Penetrating trauma etc etc
Mechanisms of heat loss - ANS-- Conduction
- Convection
- Evaporation
- Radiation
- Respiration
Basic laws of motion - ANS-Energy cannot be created or destroyed, but it can change in
form or be absorbed
Kinetic energy (KE) - ANS-Energy possessed by a body because of its motion
KE = 1/2M x V2
(M = weight, V = speed)
Double the weight = double the energy
Double the speed = quadruple the energy
Acceleration and Deceleration - ANS-An object at rest will stay at rest and an object in
motion will stay in motion unless acted on by an outside force
Acceleration - ANS-Rate at which a body in motion increases its speed
Deceleration - ANS-Rate at which a body in motion decreases its energy
Types of RTCs - ANS-- Head on collision
- Side on collision
- Rear impact
- Roll over
- Car vs motorbike
- Car vs pedestrian
, Brain stem controls - ANS-- Heart rate
- Respirations
- BP
- Body temperature
Meninges - ANS-Dura mater
- protects the brain
Arachnoid
- middle layer, laced with blood vessels.
- secured to the dura mater
- CSF is contained in the sub-arachnoid space
Piamater
- adheres to the brain, fine and delicate
- laced with small blood vessels and capillary beds, supplies nutirents
CSF - ANS-- Surrounds the brain, spinal cord in the space between the arachnoid and
piamater
- Acts as a shock absorber
- Protects the brain from jolts
Types of Skull fractures - ANS-- Linear (single crack) (most common)
- Comminuted (multiple cracks)
- Depressed
- Basilar (fractures in floor of skull)
Brain metabolism and perfusion - ANS-- Consumes 20% of oxygen
- Largest user of glucose
Blood supply
- Vertebral arteries (supply posterior brain)
- Carotid arteries (most of cerebrum)
CPP = MAP - ICP
MAP = diastolic + 1/3 pulse pressure
Frontal lobe injury - ANS-Occurs when direct impact to the front of the head
- can result in changes in personality, cognition and memory
