How is acidosis compensated?

How does the body compensate for acidosis?

Breathing faster and deeper increases the amount of carbon dioxide exhaled, which raises the blood pH back toward normal. The kidneys also try to compensate by excreting more acid in the urine.

How do you know if acidosis is compensated?


  1. Examine the pH level. If the pH is normal, but both PaCO2 and HCO3 are abnormal, compensation has occurred.
  2. Examine the PaCO2 level along with the HCO3 level. …
  3. Interpret the results.

How are alkalosis and acidosis compensated for and treated?

Your body compensates for both alkalosis and acidosis mainly through your lungs. The lungs change the alkalinity of your blood by allowing more or less carbon dioxide to escape as you breathe. The kidneys also play a role by controlling the elimination of bicarbonate ions.

How is acidosis corrected?

Intravenous (IV) treatment with a base called sodium bicarbonate is one way to balance acids in the blood. It ‘s used to treat conditions that cause acidosis through bicarbonate (base) loss. This can happen due to some kidney conditions, diarrhea, and vomiting.

How can metabolic acidosis be compensated quizlet?

Occurs as a result of the loss of an acid or an increase in the level of HCO3- in the body. The lungs compensate by a decrease in respiratory rate to increase the level of plasma CO2. The kidneys compensate by excreting more HCO3-.

How do you tell if an ABG is compensated?

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.

How do you know if ABG is compensated or uncompensated?

If the pH is not within or close to the normal ranges, then a partial-compensation exists. If the pH is back within normal ranges then a full-compensation has occurred. A non-compensated or uncompensated abnormality usually represents an acute change occurring in the body.

How is compensated respiratory acidosis treated?


  1. Bronchodilator medicines and corticosteroids to reverse some types of airway obstruction.
  2. Noninvasive positive-pressure ventilation (sometimes called CPAP or BiPAP) or a breathing machine, if needed.
  3. Oxygen if the blood oxygen level is low.
  4. Treatment to stop smoking.

What is fully compensated metabolic acidosis?

The patient would be fully compensated if he had an imbalance with a normal pH. Example: The pH is 7.43, PaCO2 is 55 mm Hg, HCO3- is 40 mEq/l. This patient has metabolic alkalosis (elevator: pH up, HCO3- up). The PaCO2 is increased, bringing the pH back within normal limits.

What is compensated metabolic alkalosis?

As a compensatory mechanism, metabolic alkalosis leads to alveolar hypoventilation with a rise in arterial carbon dioxide tension (PaCO2), which diminishes the change in pH that would otherwise occur.

Is compensation occurring in the patient with metabolic acidosis?

Respiratory compensation for metabolic acidosis increases the respiratory rate to drive off CO2 and readjust the bicarbonate to carbonic acid ratio to the 20:1 level. This adjustment can occur within minutes.
