Monitor for vision disturbances
Increased ICP:
What do we want to keep SBP?
140-160
Increased ICP:
Why do we want to hyperventilate?
CO2 is a vasodilator that increases ICP so we want to keep levels at low normal (35 mmHg) and have high PaO2 levels
Increased ICP:
What is normal ICP?
5-15 mmHg
Increased ICP:
What is CPP and how do we calculate?
Cerebral Perfusion Pressure
CPP = MAP - ICP
Normal is 70-95 mmHg
Increased ICP:
CPP of — indicates hypoperfusion of brain.
CPP of — indicates brain ischemia
less than 60
less than 40
Increased ICP:
When would you hyperventilate?
only if herniating
Increased ICP:
Why do we increase oxygenation?
because hypoxia along with hypotension has a 75% mortality rate
***give 100% FiO2
Increased ICP:
What is our optimal MAP?
greater than 90
Increased ICP:
What can we do to increase CPP?
induce HTN with DA or Dobutamine
***monitor UO closely
Increased ICP:
What drug can we give to prevent extreme rise in BP?
Nicardipine (CBB)
**Neuroprotective
Increased ICP:
What is our goal with PAWP and CVP?
PAWP 5-12 mmHG
CVP 5 mmHg
Increased ICP:
What is our goal with serum osmolarity?
keep less than 315
Increased ICP:
How often should Na and Osmolarity be measured?
