title: Oxygen therapy and vasodilator therapy in patients with chronic lung disease: the effects of episodic pulmonary hypertension during sleep and exercise performance.
abstract: In patients with chronic lung disease, we estimated the effectiveness of nocturnal oxygen therapy in eliminating episodes of sleep hypoxemia and concomitant elevations in the pulmonary arterial pressure. We also assessed the effect of vasodilators (ISDN, nifedipine) in improving exercise tolerance. Our results support the efficacy of nocturnal oxygen therapy. Vasodilators examined were not confirmed as effective or safe for wide use.
