Past studies have shown that patients with severe chronic obstructive pulmonary disease
(COPD) may experience oxygen desaturation at the cabin altitudes of pressurized aircraft …

Background Haemodynamic measurements may be superior to the 6-min walk distance
(6MWD) as outcome measures in pulmonary hypertension (PH) as they are directly linked to …

Commercial air travel is generally safe for patients with chronic obstructive pulmonary
disease when their disease is stable. All current guidelines reflect the considerable …

In an attempt to guide physicians asked by respiratory patients for advice on flight fitness, the
British Thoracic Society (BTS) have published guidelines on fitness to fly. The main potential …

To identify patients with respiratory disease, who may be at risk of developing respiratory
distress during commercial air travel, a hypoxia inhalation test (HIT) can be performed. This …

A previous study identified spirometric testing as a useful adjunct for estimating PaO 2
during altitude exposure in patients with chronic obstructive pulmonary disease (COPD). We …

Purpose To determine;(i) the effect of PH on exercise capacity, gas exchange and oxygen
pulse;(ii) the variables that correlate with mean pulmonary artery pressure (mPAP) in severe …

BACKGROUND: Patients with respiratory disease are at risk of excessive hypoxemia in the
hypobaric commercial aircraft cabin environment, and the consensus is that this is easily …

There is growing recognition of the clinical importance of pulmonary haemodynamics during
exercise, but several questions remain to be elucidated. The goal of this statement is to …

Background: Changes in pulmonary hemodynamics and cardiac function in patients with
chronic obstructive pulmonary disease (COPD) traveling to altitude have not been assessed …
