Hyperventilation is caused by a lack of which gas?

• A. Excess carbon dioxide
• B. Lack of oxygen
• C. Lack of carbon dioxide
• D. Increased oxygen

Answer: (C)

Hyperventilation happens when you breathe rapidly and blow off carbon dioxide faster than your body can produce it. The gas that becomes deficient as a result is carbon dioxide. When CO2 levels drop, the blood becomes more alkaline (respiratory alkalosis), which can cause symptoms like dizziness, tingling, and lightheadedness. Oxygen levels aren’t the issue in hyperventilation, so a lack of oxygen isn’t what drives it, and simply having more oxygen wouldn’t cause this state.
