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

Importance With increasing altitude, the partial pressure of inspired oxygen decreases and,
consequently, the Pao 2 decreases. Even though this phenomenon is well known, the extent …

Abstract Currently available European Alpine Altitude Climate Treatment (AACT) programs
combine the physical characteristics of altitude with the avoidance of environmental triggers …

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

Background Pure oxygen breathing (hyperoxia) may improve hemodynamics in patients
with pulmonary hypertension (PH) and allows to calculate right-to-left shunt fraction (Qs/Qt) …

BACKGROUND: Exercise-induced O2 desaturation contributes to dyspnea and exercise
intolerance in various respiratory diseases. This study assessed whether automated O2 …

Available evidence indicates that elevated blood ketones are associated with improved
hypoxic tolerance in rodents. From this perspective, we hypothesized that exogenous …

Background Our objective was to investigate the effect of a day-long exposure to high
altitude on peak exercise capacity and safety in stable patients with pulmonary arterial …

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 …
