How is respiratory acidosis compensation calculated?
III. Calculation: Calculated PaCO2 in Metabolic Conditions
- Metabolic Acidosis with expected compensation. PaCO2 = 1.5 x HCO3 + 8 (+/- 2) PaCO2Delta = 1.2 x BicarbDelta. PaCO2 will not typically drop below 10 mmHg in respiratory compensation.
- Metabolic Alkalosis with expected compensation. PaCO2 = 0.7 x HCO3 + 20 (+/- 1.5)
What does partially compensated respiratory acidosis mean?
Partially-compensated respiratory acidosis Partially compensated respiratory acidosis occurs when respiratory acidosis is present, with pH acidic (under 7.35) and PaCO₂ acidic (over 45 mmHg); and the metabolic system acts to correct it, marked by an HCO₃ level that’s basic (over 26 mEq/L).
What is the difference between compensated and uncompensated ABG’s?
Uncompensated means that the “Life of the Party” hasn’t noticed anything is wrong, it’s value is still within normal range, and the pH is still messed up. And full compensation happens when the “Life of the Party” has noticed something is wrong, their value has changed and the pH has gone back within normal range.
What causes blood gases to be high?
If your arterial blood gas test results are abnormal, it may mean you: Aren’t taking in enough oxygen. Aren’t getting rid of enough carbon dioxide. Have an imbalance in your blood pH (it’s too acidic or basic).
What do blood gases indicate?
The blood gas test can determine how well your lungs are able to move oxygen into the blood and remove carbon dioxide from the blood. Imbalances in the oxygen, carbon dioxide, and pH levels of your blood can indicate the presence of certain medical conditions.

What does a high blood gas mean?
If your arterial blood gas test results are abnormal, it may mean you: Aren’t taking in enough oxygen. Aren’t getting rid of enough carbon dioxide.
