what test would you do for a subarachnoid haemorrhage?
CT scan
most intracranial aneurysms are from branch points of
the circle of willis
the right middle cerebral artery supplies the
left body strength and sensation
the left middle cerebral artery supplies the
right body strength and sensation
most significant factor that determines cerebral blood flow at any given time is the
cerebral perfusion pressure
CPP (cerebral perfusion pressure) is the
effective blood pressure gradient across the brain
maintaining constant blood flow to the brain over a wife range of CPP is called
cerebral auto-regulation
cerebral oedema is a prominent cause of
subacute to chronic intracranial hypertension
cerebral oedema
state of increased brain volume as a result of an increase in water content
what is compliance?
a change in volume for any given change in pressure
elastance (the opposite of compliance) is the
change in pressure for any given change in volume
cushings relfex is a vasopressor response. i causes
hypertension
irregular breathing
bradycardia
how to manage increased ICP
head end elevation
hyperventilation
surgical decompression
hypertonic saline
venous drainage in the brain is by
venous sinuses in the dura
ischaemia is a lack of
blood flow
