Which symptom is a sign of hyperventilation syndrome?

• A. Rapid breathing
• B. Severe abdominal pain
• C. Decreased heart rate
• D. Hypoventilation

Answer: (A)

Hyperventilation syndrome is defined by breathing that is faster than normal, often deep as well. This rapid breathing is the hallmark you’d notice, since the person is venting air at an unusually high rate. The reason this is key is that the excess breathing lowers carbon dioxide in the blood, which can lead to reactions like dizziness, tingling around the lips or fingers, and chest tightness. Among the options, rapid breathing fits the pattern of hyperventilation best, while severe abdominal pain isn’t a typical feature of this condition, a decreased heart rate is not characteristic, and breathing that is too slow (hypoventilation) is the opposite of what hyperventilation involves.
