SvO2 low
Increase cardiac index
pO2 low
Increase FiO2
pCO2 low
Decrease gas to blood flow ration
pO2 high
Decrease the FiO2
SvO2 high
Decrease cardiac index
pCO2 high
Increase gas to blood flow ratio
Which blows off more CO2
If your pCO2 is low what is body state
Respiratory alkalosis
If body pCO2 is high what is the state of the body
Respiratory acidosis
Look at blood gases in what order ?
- SvO2
- pO2
- pCO2 ( and pH is tied in with this)
If bicarbonate is low
Add bicarbonate
If you are using alpha stat and your blood gas values come back for pO2 you want your what values ?
Corrected or non corrected ?
Look a corrected blood gas values
If you are using alpha stat and your blood gas values come back for pCO2 you want your what values ?
Corrected or non corrected ?
Look at non corrected values
If you are using alpha stat and your blood gas values come back for pH you want your what values ?
Corrected or non corrected ?
Non corrected blood gas values
If you are using pH stat and your blood gas values come back for pO2 you want your what values ?
Corrected or non corrected ?
Use corrected values
If you are using pH stat and your blood gas values come back for pCO2 you want your what values ?
Corrected or non corrected ?
Use temperature corrected values
If you are using pH stat and your blood gas values come back for pH you want your what values ?
Corrected or non corrected ?
Use the temperature corrected values
Alpha stat running a non corrected pCO2 or 40 we are using cerebral oximetry and blood flow to brain is too low, what do we do?
Decrease the gas to blood flow ratio (to blow off less CO2 and allow CO2 content to go up some to adjust to my oximetry) until my oximetry values come back to normal
In pediatrics – most post op neurological problems come up because of what ?
Ischemia to the brain. Not getting enough O2.
So we usually want higher BF to the brain than would be assumed
In adults – most post op neurological concerns occur because of?
GME
So we want lees Blood flow to the brain so we can lower the probability of GME’s
Finish equation
HOH -><-
HOH -><- H+ + OH -
Finish equation
CO2 + H2O -><-
CO2 + H2O -><- H+ + HCO2-
Which direction will this equation go if we add CO2 to the system ? And what will happen to the pH?
CO2 + H2O -><- H+ + HCO2-
It will be driven to the right and the pH would go down.
(Because CO2 is acidic)
