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
Normal SaO2 range
95% to 100%
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.
