What is "respiratory alkalosis"

n. alkalosis resulting from increased gas exchange in the lungs (as in hyperventilation associated with extreme anxiety or aspirin intoxication or metabolic acidosis)

Respiratory alkalosis is a medical condition in which increased respiration elevates the blood pH beyond the normal range (7.35-7.45) with a concurrent reduction in arterial levels of carbon dioxide. This condition is one of the four basic categories of disruption of acid-base homeostasis.
