Hypoventilation secondary to chronic upper airway obstruction in childhood.
A 6-year-old child manifested symptoms and signs of alveolar hypoventilation and signs of cor pulmonale caused by obstruction of the upper airway. These symptoms and signs disappeared after tonsillectomy and adenoidectomy. The relationship of upper airway obstruction to hypoventilation and cor pulmonale is discussed in the hope of renewing interest in this problem and alerting physicians to think of this possiblity early in the evaluation of such patients.
