1

what does an ABG analysis allow us to do

determine oxygenation status and acid base balance

2

what helps us to adjust our pH levels

respiratory and renal

3

what are normal values for pH

7.35-7.45

4

what are normal PaO2 levels

80-100mmhg

5

what are normal SaO2 levels

>95%

6

what are normal PaCO2 levels

35-45 mmHg

7

what are normal HCO3 levels

22-26mEq/L

8

what tells us how acidotic or alkalotic our blood is

pH

9

what tells us the amount of oxygen dissolved in arterial blood

PaO2

10

what tells us the saturation of oxygen on hemoglobin

SaO2

11

what is regulated by the lungs

PaCO2

12

what is regulated by the kidneys

HCO3

13

what is the body FASTEST way to change our pH

lungs because they regulate CO2 (acid) levels within minutes

14

how do the lungs compensate for acidosis

RR and depth will increase and CO2 will be blown off

15

how do the lungs compensate for alkalosis

RR and depth will decrease and CO2 will be retained

16

what is our "base"

bicarbonate

17

what is our "acid"

carbonic acid

18

the ______ regulate _____ levels but its a ______ system, takes hours to days

kidneys; HCO3; slower

19

how do our kidneys compensate for acidosis

H+ ions will be excreted and HCO3 will be retained

20

how do our kidneys compensate for alkalosis

H+ ions will be retained and HCO3 will be excreted

21

if pH is less than 7.35 what is it

acidosis

22

if pH is more than 7.45 what is it

alkalosis

23

if PaCO2 is less than 35 what is it

alkalosis

24

if PaCO2 is more than 45 what is it

acidosis

25

if HCO3 is less than 22 what is it

acidosis

26

if HCO3 is more than 26 what is it

alkalosis

27

what is mild hypoxemia

70-80 mmHg

28

what is moderate hypoxemia

60-70 mmHg

29

what is severe hypoxemia

<60 mmHg

30

head trauma
over sedation/drug OD
neruomuscular disorder
COPD
respiratory arrest
pneumonia
atelectasis

respiratory acidosis
