Types

There are two types of respiratory alkalosis: chronic and acute.

  • In acute respiratory alkalosis, increased levels of carbon dioxide are "blown off" by the lungs, which are hyperventilating. During acute respiratory alkalosis, the person may lose consciousness where the rate of ventilation will resume to normal.
  • In chronic respiratory alkalosis, for every 10 mM drop in pCO2 in blood, there is a corresponding 5 mM of bicarbonate ion drop. The drop of 5 mM of bicarbonate ion is a compensation effect which reduces the alkalosis effect of the drop in pCO2 in blood. This is termed metabolic compensation.

Causes

Causes of the alveolar hyperventilation seen in respiratory alkalosis include:

In addition, a respiratory alkalosis is often produced accidentally by doctors (iatrogenically) during mechanical ventilation of patients.

Symptoms

Symptoms of respiratory alkalosis are related to the decreased blood carbon dioxide levels, and include peripheral paraesthesiae. In addition, the alkalosis may disrupt calcium ion balance, and cause the symptoms of hypocalcaemia (such as tetany) with no fall in total serum calcium levels. Paresthesia or paraesthesia (in British English) is a sensation of tingling, pricking, or numbness of a persons skin with no apparent long-term physical effect, more generally known as the feeling of pins and needles or of a limb being asleep (but not directly related to the phenomenon of...

Tetany is the point at which signals from nerves (action potentials) are arriving to skeletal muscle rapidly enough in succession to cause a steady contraction, and not just a series of individual twitches. ...
