What is the purpose of compensation in metabolic acidosis?

What does the body do to compensate for metabolic 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 does Respiratory Compensation treat metabolic acidosis?

Respiratory treatments for metabolic acidosis include:

  1. bronchodilator medications (Ventolin inhaler)
  2. steroid drugs.
  3. oxygen.
  4. ventilation machine (CPAP or BiPaP)
  5. breathing machine (for severe cases)
  6. treatment to stop smoking.

How does metabolic compensation work?

Metabolic compensation (alkalosis): The body compensates for the decreased pH from the primary respiratory acidosis by increasing renal excretion of H+.

What happens in the kidney to compensate for acidosis?

The kidneys compensate for a respiratory acidosis by tubular cells reabsorbing more HCO3 from the tubular fluid, collecting duct cells secreting more H+ and generating more HCO3, and ammoniagenesis leading to increased formation of the NH3 buffer.

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.

How does the body compensate for metabolic acidosis quizlet?

The respiratory system compensates for metabolic acidosis by expelling CO2 at a faster rate (breathing rate increase). The respiratory system compensates for metabolic alkalosis by expelling CO2 at a slower rate (breathing rate decrease).

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.

Does DKA cause metabolic acidosis?

Diabetic ketoacidosis (DKA) is an acute metabolic complication of diabetes characterized by hyperglycemia, hyperketonemia, and metabolic acidosis. Hyperglycemia causes an osmotic diuresis with significant fluid and electrolyte loss.

Why does bicarbonate decrease in metabolic acidosis?

Metabolic acidosis is characterized by an increase in the hydrogen ion concentration in the systemic circulation that results in an abnormally low serum bicarbonate level.

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 the compensatory mechanism for metabolic acidosis?

As a compensatory mechanism, metabolic acidosis leads to alveolar hyperventilation with a fall in PaCO2. Normally, PaCO2 falls by 1-1.3 mm Hg for every 1-mEq/L fall in serum HCO3 concentration, a compensatory response that can occur fairly quickly.
