What is normal paCO2 - answer35-45mmHg
When is intercranial pressure considered dangerous
- answerThey rise in 15 mmHg and cerebral
herniation may occur at pressures above 25 mmHg
How is cerebral perfusion pressure calculated -
answerSubtracting intercranial pressure from mean
arterial blood pressure
What is map - answerMean arterial pressure
, If ICP increases then what happens to cerebral
perfusion pressure - answerCerebral perfusion
pressure will decrease
Through perfusion pressure must maintain at least
what - answer60 mmHg which requires maintaining
a systolic blood pressure of 110
What is cerebral herniation syndrome - answerA
critical syndrome in which swelling of the brain
forces portions of the brain through the magnum
foremen causing coma, dilation of pupils,
contralateral paralysis, elevated blood pressure and
bradycardia
When is hyperventilation indicated - answerCerebral
herniation syndrome
How many breaths per minute for children and
infants with cerebral herniation syndrome -
answer25 for children and 30 for infants
Patients with ICP should have an end title CO2 of
what - answer30 to 35
What are normal ventilation rate for adults children
and infants - answer8 to 10,15 and 20
What is non-reflow phenomenon - answerThe
inability of restoring oxygenation and blood pressure
to restore perfusion to the cortex after and anoxic
episode of 4 to 6 minutes
What artery is often teared in acute epidural
hematoma - answerMiddle meningeal artery
