ITLS Final Exam – Questions & Correct Solutions
(Pass!)
What is normal paCO2 Right Ans - 35-45mmHg
When is intercranial pressure considered dangerous Right Ans - They rise
in 15 mmHg and cerebral herniation may occur at pressures above 25 mmHg
How is cerebral perfusion pressure calculated Right Ans - Subtracting
intercranial pressure from mean arterial blood pressure
What is map Right Ans - Mean arterial pressure
If ICP increases then what happens to cerebral perfusion pressure Right
Ans - Cerebral perfusion pressure will decrease
Through perfusion pressure must maintain at least what Right Ans - 60
mmHg which requires maintaining a systolic blood pressure of 110
What is cerebral herniation syndrome Right Ans - A 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 Right Ans - Cerebral herniation
syndrome
How many breaths per minute for children and infants with cerebral
herniation syndrome Right Ans - 25 for children and 30 for infants
Patients with ICP should have an end title CO2 of what Right Ans - 30 to 35
What are normal ventilation rate for adults children and infants Right Ans -
8 to 10,15 and 20
What is non-reflow phenomenon Right Ans - The inability of restoring
oxygenation and blood pressure to restore perfusion to the cortex after and
anoxic episode of 4 to 6 minutes
