Patients with respiratory diseases may be at risk during flight because at cruising altitude an
important hypobaric hypoxia may occur. The only absolute contraindications to flying in …

BACKGROUND: Hypoxia-induced elevation in pulmonary artery pressure during air travel
may contribute to the worldwide burden of in-flight medical emergencies. The pulmonary …

Background: Predictive equations have been proposed as a simpler alternative to hypoxic
challenge testing (HCT) for determining the risk of in-flight hypoxia. Aim: To assess …

Hypoxemia occurs during air travel because the pressure in aircraft cabins is not maintained
equal to barometric pressure at sea level. Identification of patients who will develop …

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 …

Hypoxia constricts the pulmonary vessels. An increase in pulmonary vascular resistance is
seen in normal subjects during hypoxic breathing at sea level, in acclimatized lowlanders …

This study aimed to test the hypothesis that advice currently given by respiratory physicians
to potentially hypoxic patients planning air travel varies and is not evidence-based. A …

Background and objective The 6‐min walk test (6MWT) is the most widely utilized method of
assessing exercise capacity in pulmonary arterial hypertension (PAH). Cardiopulmonary …

Background Among subjects with exercise intolerance and suspected early‐stage
pulmonary hypertension (PH), early identification of pulmonary vascular disease (PVD) with …

Several publications have reported effects of hypobaric conditions in patients with chronic
obstructive pulmonary disease. To the current authors' knowledge, similar studies …
