What is a common CNS disorder that might induce respiratory alkalosis?

Respiratory alkalosis is characterized by an increase in blood pH due to decreased levels of carbon dioxide, often resulting from hyperventilation. Seizure activity can induce hyperventilation as a result of increased respiratory drive triggered by neuronal excitability in the brain. The elevated respiratory rate leads to excessive loss of carbon dioxide, causing the blood pH to rise and resulting in respiratory alkalosis.

In the context of central nervous system (CNS) disorders, seizure activity is distinctly associated with changes in breathing patterns that can lead to this particular acid-base disturbance. Understanding the mechanism helps recognize why seizure activity is the correct choice for inducing respiratory alkalosis.

Other CNS disorders such as stroke, multiple sclerosis, and cerebral palsy may have different effects on breathing and management might not necessarily lead to respiratory alkalosis, as they can also be associated with breathing difficulties or hypoventilation.
