Q

pH acidosis is when

A

Less than 7.35

1
Q

Normal values for pH

A

7.35 - 7.45

2
Q

pH alkalosis is when

A

Greater than 7.45

3
Q

Does PaO2 change pH?

A

No!!

4
Q

Normal values for paO2

A

80-100 mmHg

5
Q

Normal for PaCO2

A

35 - 45 mmHg

6
Q

PaCO2 is acidosis when

A

Greater than 45 mmHg

7
Q

PaCO2 is alkalosis when

A

Less than 35 mmHg

8
Q

PaCO2 is associated with

A

Respiratory

9
Q

HCO3 normal ranges

A

22 - 26 mEq/l

10
Q

Acidosis for HCO3

A

Less than 22 mEq/l

11
Q

Alkalosis for HCO3

A

Greater than 26 mEq/l

12
Q

What do you look at first when interpreting an ABG?

A

The pH value must be classified first.

13
Q

What should you assess second for an ABG?

A

PaCO2

14
Q

What should you assess third?

A

HCO3

15
Q

How do you identify the primary disorder?

A

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
Q

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

A

Uncompensated

17
Q

If all of the values are abnormal, then it is

A

Partially compensated

18
Q

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

A

Fully compensated
