title: Longterm favorable effect of oxygen administration on a patient with primary pulmonary hypertension.
abstract: A 17-year-old girl with primary pulmonary hypertension was treated with longterm administration of oxygen. Oxygen was delivered only at night for eight hours daily. Her clinical status has been improved for more than 17 months. Cardiac catheterization revealed almost 50 percent reduction of pulmonary vascular resistance. This is the first known report of successful treatment of primary pulmonary hypertension with oxygen administration.
