Question 0

SvO2 low

Answer 0

Increase cardiac index

Question 1

pO2 low

Answer 1

Increase FiO2

Question 2

pCO2 low

Answer 2

Decrease gas to blood flow ration

Question 3

pO2 high

Answer 3

Decrease the FiO2

Question 4

SvO2 high

Answer 4

Decrease cardiac index

Question 5

pCO2 high

Answer 5

Increase gas to blood flow ratio

Which blows off more CO2

Question 6

If your pCO2 is low what is body state

Answer 6

Respiratory alkalosis

Question 7

If body pCO2 is high what is the state of the body

Answer 7

Respiratory acidosis

Question 8

Look at blood gases in what order ?

Answer 8

1. SvO2
2. pO2
3. pCO2 ( and pH is tied in with this)

Question 9

If bicarbonate is low

Answer 9

Add bicarbonate

Question 10

If you are using alpha stat and your blood gas values come back for pO2 you want your what values ?
Corrected or non corrected ?

Answer 10

Look a corrected blood gas values

Question 11

If you are using alpha stat and your blood gas values come back for pCO2 you want your what values ?
Corrected or non corrected ?

Answer 11

Look at non corrected values

Question 12

If you are using alpha stat and your blood gas values come back for pH you want your what values ?
Corrected or non corrected ?

Answer 12

Non corrected blood gas values

Question 13

If you are using pH stat and your blood gas values come back for pO2 you want your what values ?
Corrected or non corrected ?

Answer 13

Use corrected values

Question 14

If you are using pH stat and your blood gas values come back for pCO2 you want your what values ?
Corrected or non corrected ?

Answer 14

Use temperature corrected values

Question 15

If you are using pH stat and your blood gas values come back for pH you want your what values ?
Corrected or non corrected ?

Answer 15

Use the temperature corrected values

Question 16

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?

Answer 16

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

Question 17

In pediatrics – most post op neurological problems come up because of what ?

Answer 17

Ischemia to the brain. Not getting enough O2.

So we usually want higher BF to the brain than would be assumed

Question 18

In adults – most post op neurological concerns occur because of?

Answer 18

GME

So we want lees Blood flow to the brain so we can lower the probability of GME’s

Question 19

Finish equation

HOH -><-

Answer 19

HOH -><- H+ + OH -

Question 20

Finish equation

CO2 + H2O -><-

Answer 20

CO2 + H2O -><- H+ + HCO2-

Question 21

Which direction will this equation go if we add CO2 to the system ? And what will happen to the pH?

CO2 + H2O -><- H+ + HCO2-

Answer 21

It will be driven to the right and the pH would go down.

(Because CO2 is acidic)
