Molecular oxygen (O2) is a vital element in human survival and plays a major role in a
diverse range of biological and physiological processes. Although normobaric hyperoxia …

Background Acute exercise performance can be limited by arterial hypoxemia, such that
hyperoxia may be an ergogenic aid by increasing tissue oxygen availability. Hyperoxia …

Aims The purpose of the current trial was to test the hypothesis that breathing oxygen-
enriched air increases exercise performance of patients with pulmonary arterial or chronic …

Study question We investigated whether domiciliary oxygen therapy (DOXT) increases
exercise capacity and quality of life in patients with pulmonary arterial or distal chronic …

Exercise performance is determined by oxygen supply to working muscles and vital organs.
In healthy individuals, exercise performance is limited in the hypoxic environment at altitude …

Background There is insufficient evidence to counsel patients with pulmonary hypertension
undergoing altitude or air travel. We thus aimed to study hemodynamic response of patients …

Background Many patients with pulmonary arterial or chronic thromboembolic pulmonary
hypertension (PH) wish to travel to altitude or by airplane, but their risk of hypoxia-related …

Question addressed by the study To investigate exercise performance and hypoxia-related
health effects in patients with pulmonary hypertension (PH) during a high-altitude sojourn …

Background: In patients with idiopathic pulmonary fibrosis (IPF) with isolated exertional
desaturation, there are limited data regarding the effectiveness of oxygen supplementation …
