,What condition is caused by prolonged pressure above 15 mmHg? - correct ans:Increased Intracranial
Pressure
What is the normal range for intracranial pressure? - correct ans:10-15 mmHg
What can happen if ICP is left untreated? - correct ans:Cessation of breathing and cardiac function
Arterial pressure, venous pressure, intraabdominal & intrathoracic pressure, posture, temperature,
ABGs (PaCO2 in particular) are factors that can effect - correct ans:ICP
What are the common causes of increased ICP? - correct ans:Mass (tumor, hematoma, abscess)
Cerebral edema (contusion, meningitis)
What are the 3 factors that autoregulate in the skull if there is an increase in one or the other? - correct
ans:Brain, blood & CSF
What is the net pressure gradient that drives oxygen delivery to cerebral tissue (blood flow to the brain)
mL's passing through 100g of brain tissue in 1 minute - correct ans:Cerebral Blood Flow (CBF)
What is the pressure needed to ensure blood flow to the brain called? - correct ans:Cerebral perfusion
pressure (CPP)
What is the normal range for CCP? - correct ans:60-100 mmHg
Ischemia and neuronal death is associated with a CPP < ? - correct ans:50 mmHg
ischemia and incompatible with life is associated with a CPP < ? - correct ans:30 mmHg
How do you calculate CPP? - correct ans:MAP-ICP
, MAP=SBP+DBP(x2)/3
Example:
BP - 205/120/ICP - 22
205 + 240 ÷ 3
MAP= 148
CPP 126
What are the early signs of increased ICP? - correct ans:Decreased consciousness (most significant sign)
Excruciating, constant headache
Nuchal rigidity (stiff neck)
Vomiting / nausea
What assessment concentrates on neurologic function and is useful to determine the level of
consciousness and monitor response to treatment? - correct ans:Glasgow Coma Scale
GCS eye opening response - correct ans:4 = spontaneous
3 = to speech
2 = to pain
1 = none
GCS verbal response - correct ans:5-Oriented
4-Confused conversation
3-Inappropriate words
2-Incomprehensible sounds
1-None
GCS motor response - correct ans:6-Obeys commands
