When Does Uncompensated Acidosis Occur?

Patients are uncompensated when they have an imbalance, but the compensating mechanism remains normal. Example: The pH is 7.16, PaCO2 is 65 mm Hg, HCO3- is 24 mEq/l. This patient has respiratory acidosis (seesaw: pH down, PaCO2 up).

What causes uncompensated metabolic acidosis?

Metabolic acidosis develops when too much acid is produced in the body. It can also occur when the kidneys cannot remove enough acid from the body.

How do you know if ABG is compensated or uncompensated?

When PaCO2 and HCO3 values are high but pH is acidic, then it indicates partial compensation. It means that the compensatory mechanism tried but failed to bring the pH to normal. If pH is abnormal and if the value of either PaCO2 or HCO3 is abnormal, it indicates that the system is uncompensated.
