What does ICP stand for?
Increased intracranial pressure
What is a hematoma?
Bruises
What is RICE?
Rest, Ice, Compression and Elevation
What are the three main components of the skull?
Brain tissue, blood and cerebrospinal fluid
What is the primary injury in ICP?
It is injury which happens at the time of the accident
What is a secondary injury in ICP?
It is the resulting hypoxia, ischaemia, hypotension, oedema or increased ICP that results in injury to three main components
What is intracranial pressure ?
It is the hydrostatic force measured in the brain CSF compartment
What is the Monro-Kellie doctrine?
It is the principle that states that a change in blood, brain or CSF volume results in reciprocal changes in one or both of the other two components.
Does the Monro-Kellie doctrine apply to people with open skulls?
Nope
What are the three types of cerebral oedema?
