1

Goal of an ABG?

identify acidosis or alkalosis

2

Rule of the B's

if pH and BICARB are BOTH in the same direction then it is METABOLIC

3

If pH and bicarb are in different directions...

respiratory

4

normal pH

7.35-7.45

5

normal bicarb

22-26

6

What do you see with low pH...

acidosis
as the pH goes, so does my patient
-low pH, low S/S

hyporeflexic, bradycardic, bradypnec, lethargy, obtunded, coma

7

obtunded

1 step lower than lethargic

8

What do you see with high pH...

alkalosis
as the pH goes, so does my patient
-high pH, high S/S

irritability, hyperreflexic, tachypnea, tachycardic

9

what is a hyporeflexic finding?

0, +1

10

what is a normoreflexic finding?

+2

11

what is a hyperreflexic finding?

+3, +4

12

paralytic ileus

down

13

borborygmi

up; increased bowel sounds

14

who would need a ambu bag at bedside?

acidosis--resp arrest, down S/S

15

who would need suctioning at the bedside?

alkalosis--seize, up S/S

16

Potassium and pH...

as goes my pH, so does my patient except potassium

-opposite

17

acidosis...potassium is...?

high

18

alkalosis...potassium is...?

low

19

Kussmaul breathing

MacKussmaul

-metabolic acidosis

20

over/under ventilate, translate...

overventilation= respiratory alkalosis

underventilation= respiratory acidosis

21

Example: pt is overusing breathing techniques during labor

over ventilating= respiratory alkalosis

22

Example: near drowing

respiratory acidosis

23

Example: emphysema, air trapping

respiratory acidosis

24

When assessing ventilation, think...

gas exchange at the lung level...not RR

25

Example: Your patient is on a PCA pump, what acid base imbalance would indicate backing off the pump?

respiratory acidosis

26

Prolonged gastric suction or vomitting?

Metabolic alkalosis

27

For everything that isnt lung and isnt vomitting/suctioning?

metabolic acidosis

28

Patient with hyperemesis who is now dehydrated?

metabolic acidosis

29

acute renal failure...

metabolic acidosis

30

If you don't know it....

metabolic acidosis
