Doctors recommend treatment for respiratory alkalosis based on what is causing the underlying illness. If the cause is related to a ventilator setting, such as it being too fast, having too high a supplemental oxygen setting, or giving too large a volume in each breath, the doctor may modify the settings so that the person can breathe more suitably. Because respiratory alkalosis is not usually life-threatening and the body often works to correct the imbalance, a doctor may not treat the higher-than-normal pH level aggressively.
While respiratory alkalosis is not life-threatening, the underlying cause might be. The condition will likely resolve if a person or doctor corrects the underlying cause. The body may try to self-correct the pH imbalance that comes with respiratory alkalosis, such as by having the kidneys increase excretion of alkaline and reduce excretion of acid.

Medically reviewed by Stacy Sampson, D.
Causes Symptoms Diagnosis Treatments Outlook Breathing too fast can cause a person to go into respiratory alkalosis. Share on Pinterest Symptoms of respiratory alkalosis include anxiety and lightheadedness. By contrast, respiratory alkalosis is characterized by decreased p CO 2 a due to excessive alveolar ventilation and resulting excessive elimination of CO 2 from blood.
Disease in which, due to reduced oxygen in blood hypoxemia , the respiratory center is stimulated can result in respiratory alkalosis. Examples here include severe anemia, pulmonary embolism and adult respiratory syndrome.
Hyperventilation sufficient to cause respiratory alkalosis can be a feature of anxiety attacks and response to severe pain. One of the less welcome properties of salicylate aspirin is its stimulatory effect on the respiratory center. This effect accounts for the respiratory alkalosis that occurs following salicylate overdose. Finally, overenthusiastic mechanical ventilation can cause respiratory alkalosis. Reduced bicarbonate is always a feature of metabolic acidosis.
This occurs for one of two reasons: increased use of bicarbonate in buffering an abnormal acid load or increased losses of bicarbonate from the body.
Diabetic ketoacidosis and lactic acidosis are two conditions characterized by overproduction of metabolic acids and consequent exhaustion of bicarbonate. In the first case, abnormally high blood concentrations of keto-acids b-hydroxybutyric acid and acetoacetic acid reflect the severe metabolic derangements which result from insulin deficiency. All cells produce lactic acid if they are deficient of oxygen, so increased lactic acid production and resulting metabolic acidosis occur in any condition in which oxygen delivery to the tissues is severely compromised.
Examples include cardiac arrest and any condition associated with hypovolemic shock e. The liver plays a major role in removing the small amount of lactic acid that is produced during normal cell metabolism, so that lactic acidosis can be a feature of liver failure. Abnormal loss of bicarbonate from the body can occur during severe diarrhea.
If unchecked, this can lead to metabolic acidosis. Failure to regenerate bicarbonate and excrete hydrogen ions explains the metabolic acidosis that occurs in renal failure. Bicarbonate is always raised in metabolic alkalosis. Rarely, excessive administration of bicarbonate or ingestion of bicarbonate in antacid preparation can cause metabolic alkalosis, but this is usually transient.
Abnormal loss of hydrogen ions from the body can be the primary problem. Bicarbonate which would otherwise be consumed in buffering these lost hydrogen ions consequently accumulates in blood. Gastric juice is acidic and gastric aspiration or any disease process in which gastric contents are lost from the body represents a loss of hydrogen ions.
The projectile vomiting of gastric juice, for example, explains the metabolic alkalosis that can occur in patients with pyloric stenosis. Severe potassium depletion can cause metabolic alkalosis due to the reciprocal relationship between hydrogen and potassium ions. It is vital for life that pH does not waiver too far from normal, and the body will always attempt to return an abnormal pH towards normal when acid-base balance is disturbed.
Compensation is the name given to this life-preserving process. So long as the ratio is normal, pH will be normal. Consider the patient with metabolic acidosis whose pH is low because bicarbonate [HCO 3 — ] is low.
To compensate for the low [HCO 3 — ] and restore the all-important ratio towards normal the patient must lower his p CO 2 a. Chemoreceptors in the respiratory center of the brain respond to a rising hydrogen ion concentration low pH , causing increased ventilation hyperventilation and thereby increased elimination of carbon dioxide; the p CO 2 a falls and the ratio [HCO 3 — ] : p CO 2 a returns towards normal.
Compensation for metabolic alkalosis in which [HCO 3 — ] is high, by contrast, involves depression of respiration and thereby retention of carbon dioxide so that the p CO 2 a rises to match the increase in [HCO 3 — ]. However, depression of respiration has the unwelcome side effect of threatening adequate oxygenation of tissues.
For this reason respiratory compensation of metabolic alkalosis is limited. Primary disturbances of p CO 2 a respiratory acidosis and alkalosis are compensated for by renal adjustments of hydrogen ion excretion which result in changes in [HCO 3 — ] that compensate appropriately for primary change in p CO 2 a.
Thus the renal compensation for respiratory acidosis raised p CO 2 a involves increased reabsorption of bicarbonate, and renal compensation for respiratory alkalosis reduced p CO 2 a involves reduced bicarbonate reabsorption. The concept of acid-base balance during compensation is conveyed visually in Fig. Table II summarizes the blood gas results that characterize all four acid-base disturbances before and after compensation.
Respiratory acidosis primary increase in p CO 2. Repiratory alkalosis primary decrease in p CO 2. Metabolic acidosis primary decrease in bicarb. Metabolic alkalosis primary increase in bicarb.
Some common causes. Hyper- ventilation Anxiety attacks Stimulation of brain respiratory center. Renal failure Diabetic ketoacidosis Circulatory failure - clinical shock lactic acidosis. Bicarbonate admini- stration. Potassium depletion. Compen- satory mechanism. RENAL increase bicarbonate. RENAL decrease bicarbonate. Initial blood gas results uncompen- sated. Blood gas results after partial compen- sation. Limited compen- sation in metabolic alkalosis. Blood gas results after full compen- sation.

In the second case, compensation occurs over days rather than hours. If compensation results in return of pH to normal then the patient is said to be fully compensated. But in many cases the compensation returns pH towards normal without actually achieving normality; in such cases the patient is said to be partially compensated.
It might be assumed from the above discussion that all patients with acid-base disturbance suffer from only one of the four categories of acid-base balance. This may well be the case, but in particular circumstances patients can present with more than one disturbance.
For example, consider the patient with a chronic lung disease such as emphysema who has a long-standing partially compensated respiratory acidosis.

This can be due to: Fever Being at a high altitude Lack of oxygen Liver disease Lung disease, which causes you to breathe faster hyperventilate Aspirin poisoning Metabolic alkalosis is caused by too much bicarbonate in the blood. 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.
Exams and Tests. The health care provider will perform a physical exam and ask about your symptoms. Laboratory tests that may be ordered include: Arterial blood gas analysis. Electrolytes test, such as basic metabolic panel to confirm alkalosis and show whether it is respiratory or metabolic alkalosis.
