Normal values for pH

7.35 - 7.45

1

pH acidosis is when

Less than 7.35

2

pH alkalosis is when

Greater than 7.45

3

Does PaO2 change pH?

No!!

4

Normal values for paO2

80-100 mmHg

5

Normal for PaCO2

35 - 45 mmHg

6

PaCO2 is acidosis when

Greater than 45 mmHg

7

PaCO2 is alkalosis when

Less than 35 mmHg

8

PaCO2 is associated with

Respiratory

9

HCO3 normal ranges

22 - 26 mEq/l

10

Acidosis for HCO3

Less than 22 mEq/l

11

Alkalosis for HCO3

Greater than 26 mEq/l

12

What do you look at first when interpreting an ABG?

The pH value must be classified first.

13

What should you assess second for an ABG?

PaCO2

14

What should you assess third?

HCO3

15

How do you identify the primary disorder?

Look at PaCO2 and HCO3 values. The one that has moved in the same direction as the pH (acidosis or alkalosis) indicates the primary disorder.

16

If the pH is abnormal and ONE other parameter is abnormal, then the situation is

Uncompensated

17

If all of the values are abnormal, then it is

Partially compensated

18

If pH is normal but both PaCO2 and HCO3 are abnormal, then it is

Fully compensated
