Background and objective: Air travel guidelines recommend using baseline arterial oxygen
levels and the hypoxic challenge test (HCT) to predict in‐flight hypoxaemia and the …

Background: Supplemental oxygen during air travel is recommended when in-flight PaO 2 is
expected to fall below 6.6 kPa in patients with lung disease. Sea level oxygen saturation by …

Background Limited data are available comparing air travel with the hypoxia inhalation test
(HIT) in passengers with COPD. The aim of this study was to assess the predictive capability …

BACKGROUND: Patients with chronic pulmonary diseases are at increased risk of
hypoxemia when travelling by air. Screening guidelines, predictive equations based on …

Background The reduced pressure in the aircraft cabin may cause significant hypoxaemia
and respiratory distress in patients with chronic obstructive pulmonary disease (COPD) …

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 …

Background Patients with chronic pulmonary diseases are at increased risk of hypoxemia

At the present time, commercial aircraft cabins are required to be pressurized to the
equivalent of 8,000 feet or less. Although in-flight medical emergencies are infrequent, some …

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 …
