ABGs

Question 1

What ABG lab will go really high when oxygen is administered?

Answer 1

PaO2

Question 2

What is always important to take into consideration when the PaO2 is really high?

Answer 2

how much oxygen is being administered

Question 3

If the pH is less than 7.40 where is it headed?

Answer 3

towards acidosis

Question 4

If the pH is greater than 7.40 where is it headed?

Answer 4

towards alkalosis

Question 5

What ABG component do we control with the ventilator?

Answer 5

pCO2

Question 6

What is the respiratory component of the ABG?

Answer 6

pCO2

Question 7

What kind of breaths do we give to blow off more CO2 thus decreasing the levels?

Answer 7

increased breaths or deeper breaths

Question 8

What kind of breaths do give them to retain CO2 thus increasing the levels?

Answer 8

Fewer breaths or shallower breaths

Question 9

What is the acidity factor of the ABG lab?

Answer 9

pCO2

Question 10

The more CO2 the patient has, are they more acidotic or alkalotic?

Answer 10

acidotic (and the less CO2 the more alkalotic they are)

Question 11

What is the normal range for pCO2?

Answer 11

35-45

Question 12

What is the normal range for HCO3?

Answer 12

22-26

Question 13

Can you do anything with the ventilator to fix HCO3?

Answer 13

no because it is a metabolic component

Question 14

What do the HCO3 levels indicated?

Answer 14

the higher the level the more alkalotic and the lower the level the more acidotic

Question 15

If the pH is normal but either the HCO3 or pCO2 is out of whack, what is it called?

Answer 15

FULLY compensated

Question 16

If the pH is not normal but both the pCO2 and HCO3 are out of whack, what is it called?

Answer 16

PARTIALLY compensated

Question 17

If the pH is not normal and only the pCO2 OR the HCO3 (NOT both of them, just one), what is it called?

Answer 17

uncompensated

Question 18

pH is very high
pCO2 is low
HCO3 is high

Answer 18

Combined respiratory and metabolic alkalosis

Question 19

pH is low
pCO2 is normal
HCO3 low

Answer 19

Metabolic Acidosis (uncompensated)

Question 19

pH is very low
pCO2 is high
HCO3 is low

Answer 19

Combined respiratory and metabolic acidosis

Question 20

pH is very low
pCO2 is very high
HCO3 is normal

Answer 20

Respiratory Acidosis (uncompensated)

Question 21

pH is low
pCO3 is high
HCO3 is high

Answer 21

Partially compensated respiratory acidosis

Question 22

pH is low
pCO3 is low
HCO3 is high

Answer 22

Partially compensated Metabolic Acidosis

Question 23

If patient is respiratory alkalotic, what ventilation setting will help correct it?

Answer 23

decreasing ventilation rate and volume - holding onto more CO2

Question 24

If patient is Respiratory Acidosis, what ventilation setting will help correct it?

Answer 24

Increasing the rate and volume, thus blowing off CO2 and decreasing acidosis
