Importance There are no established measures to prevent nocturnal breathing disturbances
and other altitude-related adverse health effects (ARAHEs) among lowlanders with chronic …

This case–control study evaluates a possible association between high altitude pulmonary
hypertension (HAPH) and sleep apnoea in people living at high altitude. Ninety highlanders …

Background Chronic obstructive pulmonary disease (COPD) may predispose to symptomatic
pulmonary hypertension at high altitude. We investigated hemodynamic changes in …

Background Patients with COPD may experience acute mountain sickness (AMS) and other
altitude-related adverse health effects (ARAHE) when traveling to high altitudes. This study …

Importance During mountain travel, patients with chronic obstructive pulmonary disease (COPD)
are at risk of experiencing severe hypoxemia, in particular, during sleep. Objective To …

Introduction: Stable patients with pulmonary arterial or chronic thromboembolic pulmonary
hypertension (PH) wish to undergo altitude sojourns or air travel but fear disease worsening. …

Objective: To evaluate the effects of acute exposure to high altitude and preventive dexamethasone
treatment on postural control in patients with chronic obstructive pulmonary disease (…

This trial evaluates whether nocturnal oxygen therapy (NOT) during a stay at 2048 m improves
altitude-induced exercise intolerance in lowlanders with chronic obstructive pulmonary …

Introduction We investigated whether nocturnal oxygen therapy (NOT) mitigates the increase
of pulmonary artery pressure in patients during daytime with chronic obstructive pulmonary …

Background: Chronic obstructive pulmonary disease (COPD) is associated with cardiovascular
disease. We investigated whether sleeping at altitude increases nocturnal heart rate (HR…
