You asked: How does the respiratory system compensate for metabolic alkalosis?

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 does the respiratory system response to metabolic alkalosis?

A typical respiratory response to all types of metabolic alkalosis is hypoventilation leading to a pH correction towards normal. Increases in arterial blood pH depress respiratory centers. The resulting alveolar hypoventilation tends to elevate PaCO2 and restore arterial pH toward normal.

What is the compensatory mechanism for 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 would the respiratory system compensate for metabolic alkalosis quizlet?

respiratory compensation for metabolic alkalosis occurs when the elevated pH inhibits the respiratroy center. the rate and depth of ventilation are decreased, causing retention of carbon dioxide. the ratio of HCO3 to H2CO3 is reduced toward normal.

Which body system is compensating for the metabolic alkalosis?

COMPENSATION OF RESPIRATORY AND METABOLIC ACIDOSIS OR ALKALOSIS. For compensation to occur, the renal and respiratory systems work together to regain and maintain a normal blood pH level.

What is the difference between respiratory and metabolic alkalosis?

Respiratory acid-base disorders are commonly due to lung diseases or conditions that affect normal breathing. Disorders that affect metabolism and cause changes in pH due to either increased acid production or decreased base are called metabolic acidosis (low pH) and metabolic alkalosis (high pH).

How do you fix metabolic alkalosis?

Metabolic alkalosis is usually treated by replacing water and electrolytes (sodium and potassium) while treating the cause. Rarely, when metabolic alkalosis is very severe, dilute acid is given intravenously. In respiratory alkalosis, the first step is to ensure that the person has enough oxygen.

What is the most common form of compensation for metabolic alkalosis?

Outlook of metabolic alkalosis. Metabolic alkalosis most commonly results from severe cases of vomiting that cause you to lose the acidic fluids in your stomach. This can usually be reversed by treatment with a saline solution. It can also be the result of a potassium deficiency or a chloride deficiency.

What is the most common cause of metabolic alkalosis?

The most common causes are volume depletion (particularly when involving loss of gastric acid and chloride (Cl) due to recurrent vomiting or nasogastric suction) and diuretic use. Metabolic alkalosis involving loss or excess secretion of Cl is termed chloride-responsive.

What are the symptoms of metabolic alkalosis?

Symptoms of alkalosis can include any of the following:

  • Confusion (can progress to stupor or coma)
  • Hand tremor.
  • Lightheadedness.
  • Muscle twitching.
  • Nausea, vomiting.
  • Numbness or tingling in the face, hands, or feet.
  • Prolonged muscle spasms (tetany)

How does the renal system compensate for metabolic acidosis?

Metabolic Acidosis

If the kidneys are also functioning, the renal compensation for acidosis is to excrete acidic urine. Chronically, the renal excretion of H+ is enhanced as the renal ability to produce ammonium from glutamine is induced.

How does body compensate for metabolic acidosis?

As blood pH drops (becomes more acidic), the parts of the brain that regulate breathing are stimulated to produce faster and deeper breathing (respiratory compensation). Breathing faster and deeper increases the amount of carbon dioxide exhaled. The kidneys also try to compensate by excreting more acid in the urine.

What effect do you think raising the PCO2?

It is the change in local PaCO2 as well as the change in pH that causes a change in minute ventilation. Under normal physiologic conditions, an increase in PCO2 causes a decrease in pH, which will increase minute ventilation and therefore increase alveolar ventilation to attempt to reach homeostasis.

What is the meaning of metabolic alkalosis?

A decrease in pH below this range is acidosis, an increase over this range is alkalosis. Metabolic alkalosis is defined as a disease state where the body’s pH is elevated to greater than 7.45 secondary to some metabolic process.

How do Diuretics cause metabolic alkalosis?

The generation of a metabolic alkalosis with diuretic therapy is primarily due to contraction of the extracellular fluid space caused by urinary losses of a relatively HCO3 -free fluid.
