C. Management
Management of patients with corpulmonale consists of treatment of the underlying disease and correction of hypoxemia with continuous oxygen administration. A minimum of 15 h of oxygen daily to keep the PaO2 greater than 60 mmHg may provide a modest improvement in survival and activity levels. Digoxin is indicated only if atrial fibrillation is present. Furosemide is given to relieve bothersome bilateral pitting edema at doses of 20–40 mg daily.
