Hyperventilation produces respiratory alkalosis by causing which change in the blood?
AAn excess of carbon dioxide
BAn excess of bicarbonate ion
CA deficiency of bicarbonate ion
DA deficiency of carbon dioxide
Answer & Solution
Correct answer: D. A deficiency of carbon dioxide
1. Hyperventilation is breathing that is deeper or more frequent than normal.
2. It drives too much carbon dioxide out of the lungs.
3. Less carbon dioxide means less carbonic acid, so the blood turns alkaline.
4. That is why the disorder is named a primary carbonic acid and carbon dioxide deficiency.
5. An excess of carbon dioxide would produce the opposite state, respiratory acidosis.
