This clinical review summarizes evidence on managing altitude-related risks for patients with COPD. It concludes that preventive treatments like nighttime oxygen, acetazolamide, or dexamethasone can reduce adverse effects such as severe hypoxemia and excessive sleep apnea.
This narrative review examines the risks and management of high-altitude travel for patients with chronic obstructive pulmonary disease (COPD). Central results indicate that patients with moderate to severe COPD experience dyspnea, exercise limitation, and sleep disturbances at altitudes up to 3,100 meters. Preventive interventions, including nighttime oxygen, acetazolamide, and dexamethasone, have been shown in trials to reduce the risk of ARAHE and improve specific outcomes like oxygenation and sleep apnea. The implications are that clinicians must provide specific pretravel counseling and consider preventive measures to ensure safer altitude journeys for COPD patients.
