title: Primary alveolar hypoventilation managed by negative-pressure ventilators.
abstract: A girl who had a history of repeated apnea was found to have absent chemical drive to ventilation and, on sleep monitoring, both central and obstructive types of apnea. She is currently undergoing successful mechanical ventilation at night with negative-pressure ventilators.
