- Intracranial regulation concept
Answer
- normal and abnormal processes of intracranial function
- intra
within
- cranium
bone structures that cover the brain
- brain
circulatory system and duramater
- regulation compliance and maintenance of balance
- Central nervous system function
Answer
- system integrity 1 / 4
- homeostasis
- oxygen
- glucose
- CSF
- filtration
- Parts of brain protective barrier
Answer
- scalp
- skull
- dura mater
- arachnoid
- subarachnoid space with CSF
- pia mater
- brain
- blood vessels of the brain
Answer
- basilar artery
- circle of Willis
- anterior cerebral artery
- middle cerebral artery
- posterior cerebral artery
- Factors that impair ICR
Answer
- impaired perfusion 2 / 4
- compromised neurotransmission
- glucose regulation
- pathology
- Cerebral autoregulation
Answer
- ability of the brain to maintain blood flow
- fairly constant rate of 1000cc/min
- MAP > 130 cab be lost
- Compliance
Answer
- shunting of cerebrospinal fluid and venous blood to make room for expanding brain tissue
- the brain can shift to make space but this is delicate and dangerous
- Cerebral edema
Answer
- increased brain water content
- intracellular or extracellular
- cytotoxic
- vasogenic
- interstitial
- osmotic
- Hydrocephalus 3 / 4
Answer
- increased CSF (dilated ventricles or imparied absorption or obstruction)
- anything that increases the intracranial contents can cause hydrocephalus
- Hydrocephalus causes
Answer
- CSF obstruction
- clogged arachnoid villi
- impaired CSF reabsorption
- SAH and TBI can be cause
- temporary vs long-term treatments
- Hematoma
Answer
- a collection of blood outside of blood vessels
- mostly clotted
- Hemorrhage
Answer
- active ongoing bleeding
- Cerebral Perfusion Pressure (CPP)
