Healthstream ICU Knowledge
1. Intracranial hemorrhage's goal for treatment?: Stop bleeding. Decrease icp.
2. Subdural hematoma?: bleeding between covering of brain (dura) and surface ofbrain.
Compress brain tissue , leadin to brain dead. Most pt do not recover.
3. Epidural hematoma?: covering of the brain (dura) peel away from skull (fromskull
fracture).Wake up and die. Changes in vital signs are late signs.
4. SubArachnoid hemorrhage (SAH)?: aneurysm of artery in brain, causing rup-ture. This is a
type of hemorhagic stroke. Risk for repeated bleeding is 35% within. First 14 days post first
bleed. Vasospasm is a common complication of SAH. Cerebral angiogram can dx cerebral
aneurysm. A ruptured aneurysm has a risk for death of40% , 08% disable after rupture.
5. Normal ICP for adult?: less than 15mmHg. When treating high ICP, the goal is to be 20
mmHg ICP.
6. What is cushing's triad?: three symptoms that indicate brian damage from high ICP.
BRADYCARDIA, RESP DEPRESSION, HYPERTENSION.
7. What factors increase ICP?:suction, any stimulations.
8. Glascow score of 5 indicate?:
9. Cerebral angiogram?: visualize cerebral blood flow and blood vessels. Can remove clot in
bv at time of process.Insertion of dye through femoral artery. Pt liesflat. Indicated for:
atherosclerosis, dissection, tumor, aneurysm, av malformation, stroke. Not for kidney failure,
bleeding issue, allergic to dye (iodine& shellfish). Cerebral angiogram can dx cerebral
aneurysm. A ruptured aneurysm has a risk fordeath of 40% , 08% disable after rupture.
10. Av malformation?: l connection between artery and vein without capillary bedbetween in
brain blood vessels. Leading to high pressure in veins (as vein is receiving blood too quick!->
weaken bv-> risk aneurysm.
11. WHY IS AVM BAD?: 1 risk of aneurysm rupture. 2 enlarged avm will put pressure on
surrounding brain. 3 cells that only gets oxy from capillary bed will die.
12. Types of AV MALFORMATION?: dural fistula, venous malformation, caver-noma,
capillary telangiectasia.
13. two locations of AVM?: BRAIN & SPINE.
14. treatment for avm?: embolization - deliver glue/ obstructive materialsinto avm,thus, blood
cant flow into avm to cause rupture.
15. what test is used to locate what part of the brain is damaged by seizure orstroke. this test
combines both neuroimaging anf neuropsychological tests?-
: wada test- inject barbiturate into carotid artery to shut down one brian hemisphereand
evaluate the opposite hemisphere..
16. How to know if a person will be allergic to angiogram dye?: allergic to iodineand shellfish.
17. A pt with cerebral aneurysm is dx. What can the medical team do to secureit in preventing
rupture of the aneurysm?: clipping , endovascular coiling.
18. What is the procedure of opening the skull?: craniotomy.
19. What is clipping?: clip at the neck of aneurysm to block normal blood floe fromentering;
thus, stop it from stretching further and eventually rupture.
