Supplemental oxygen for COPD patients with nocturnal desaturations?

Nocturnal efficiency and tolerance of a demand oxygen delivery system in COPD patients with nocturnal hypoxemia.

OBJECTIVES We compared the efficacy of the standard nasal cannula and the demand oxygen delivery system (DODS) during sleep in patients with COPD. SUBJECTS Twenty patients with moderate or severe COPD were included in the study. METHODS Four consecutive polysomnographic recordings were performed under the following conditions: DODS powered by compressed air (night 1 [N1]); oxygen delivered ...

Predicting walking-induced oxygen desaturations in COPD patients: a statistical model.

BACKGROUND Oxygen desaturation during walking can have important consequence on prognosis of COPD patients. However, a standard 6-min walk test (6MWT), useful in detecting desaturation in COPD patients, can be difficult to execute in some settings of COPD management, as in the community healthcare service. We evaluated a new scoring system for the risk of oxygen desaturation during walking in C...

Nocturnal ventilatory support in patients with cystic fibrosis: comparison with supplemental oxygen.

Progressive deterioration of lung function in cystic fibrosis (CF) patients may lead to significant hypoxaemia and hypercapnia, especially during sleep. The effects of bi-level noninvasive positive pressure nasal mask ventilation (NIPPV) on respiration and sleep were compared to those of low-flow oxygen therapy in six CF patients (mean +/- SD age 22.3 +/- 4.7 yrs, with severe lung disease (forc...

Supplemental oxygen during pulmonary rehabilitation in patients with COPD with exercise hypoxaemia.

BACKGROUND Supplemental oxygen in patients with chronic obstructive pulmonary disease (COPD) and exercise hypoxaemia improves exercise capacity and dyspnoea. However, the benefit of oxygen during pulmonary rehabilitation in these patients is still unknown. METHODS Twenty five patients with stable COPD (mean (SD) forced expiratory volume in one second (FEV(1)) 0.76 (0.29) l and 30.0 (9.89)% pr...
