Normal pH levels
|
7.35 to 7.45
|
|
Normal PaCO2 levels
|
35 to 45 mmHg
|
|
Normal Bicarbonate levels
|
22 to 26 mEq/L
|
|
Normal PaO2 levels
|
80 to 100 mmHg

|
|
First step in interpreting ABG results.
|
Check the pH level.
low <7.35 (Acidosis) or high >7.45 (Alkalosis. |
|
Second step in interpreting ABG results.
|
Determine the paco2 level.
Low <35 mmHg (hypocapnia) respiratory alkalosis or High >45 mmHg (hypercapnia) respiratory acidosis. |
|
Third step in interpreting ABG results.
|
Check the bicarbonate level.
Low <22 mEq/L or High >26 mEq/L. Does is correspond with the pH change. |
|
Forth step in interpreting ABG results.
|
Look for compensation.
One value indicates the primary source of the pH change; the other, the body's effort to compensate for the disturbance. |
|
Fith step in interpreting ABG results.
|
Determine Pao2 and Sao2 levels.
|
|
How do you calculate the anion gap?
|
First add the chloride level and the bicarbonate level. Second subtract the first total amount from the sodium level. Normal range 8 to 14 mEq/L.
