What is the classic breathing pattern in hyperventilation syndrome?

• A. Slow shallow breathing
• B. Rapid or deep breathing
• C. Normal breathing
• D. Apneic spells

Answer: (B)

Hyperventilation syndrome is driven by anxiety and involves overbreathing, where ventilation is increased in both rate and depth. This rapid or deep breathing lowers arterial CO2 (hypocapnia), leading to respiratory alkalosis and symptoms like dizziness and perioral tingling. The hallmark pattern is fast, deep breaths rather than slow shallow breathing or normal breathing, or pauses in breathing. Recognize that calming the patient and retraining breathing to a slower, diaphragmatic pattern helps restore CO2 levels.
