How does respiratory alkalosis occur?

Respiratory alkalosis is caused by factors such as hyperventilation and central nervous system disorders. It is a very common condition, and in severe cases, symptoms such as dizziness, paresthesia, and intermittent tetany may occur. During hysterical episodes, excessive ventilation due to psychological factors, meningitis, or brain injury may occur, or it may result from stimulation of the respiratory center by substances such as salicylates or ammonium salts. The main treatment for respiratory alkalosis involves actively addressing the underlying cause. Measures can include increasing the dead space of the airway to reduce CO2 loss, and having the patient inhale 5% carbon dioxide. In severe cases of respiratory alkalosis, respiratory depressants may be used to help regulate breathing.
