The purpose of this study is to evaluate if supplemental oxygen during air travel can be reliably titrated using a Hypoxia-altitude simulation test (HAST). Also, the effect of oxygen supplementation given with the various oxygen equipment allowed for air travel is studied.
International guidelines recommend supplemental oxygen if PaO2 < 6.7 kPa (50 mmHg) during air travel. Hypobaric chamber exposure is the ideal test but is not widely available. In clinical practice, the HAST has been recommended as the preferable test for pre-flight evaluation, and is used with increasing frequency. The oxygen dose during air travel has been recommended titrated during HAST. In the study, supplemental oxygen titration during hypobaric chamber exposure is compared to oxygen titration during HAST, to evaluate if HAST can be used with confidence to titrate the amount of supplemental oxygen needed during air travel.

A disease of chronic diffuse irreversible airflow obstruction. Subcategories of COPD include CHRONIC BRONCHITIS and PULMONARY EMPHYSEMA.
Hypertrophy and dilation of the RIGHT VENTRICLE of the heart that is caused by PULMONARY HYPERTENSION. This condition is often associated with pulmonary parenchymal or vascular diseases, such as CHRONIC OBSTRUCTIVE PULMONARY DISEASE and PULMONARY EMBOLISM.
A respiratory stimulant that enhances respiration by acting as an agonist of peripheral chemoreceptors located on the carotid bodies. The drug increases arterial oxygen tension while decreasing arterial carbon dioxide tension in patients with chronic obstructive pulmonary disease. It may also prove useful in the treatment of nocturnal oxygen desaturation without impairing the quality of sleep.
A subcategory of CHRONIC OBSTRUCTIVE PULMONARY DISEASE. The disease is characterized by hypersecretion of mucus accompanied by a chronic (more than 3 months in 2 consecutive years) productive cough. Infectious agents are a major cause of chronic bronchitis.
A condition associated with multiple episodes of sleep apnea which are distinguished from obstructive sleep apnea (SLEEP APNEA, OBSTRUCTIVE) by the complete cessation of efforts to breathe. This disorder is associated with dysfunction of central nervous system centers that regulate respiration. This condition may be idiopathic (primary) or associated with lower brain stem lesions; chronic obstructive pulmonary disease (LUNG DISEASES, OBSTRUCTIVE); HEART FAILURE, CONGESTIVE; medication effect; and other conditions. Sleep maintenance is impaired, resulting in daytime hypersomnolence. Primary central sleep apnea is frequently associated with obstructive sleep apnea. When both forms are present the condition is referred to as mixed sleep apnea (see SLEEP APNEA SYNDROMES). (Adams et al., Principles of Neurology, 6th ed, p395; Neurol Clin 1996;14(3):611-28)
COPD (chronic obstructive pulmonary disease)
COPD (chronic obstructive pulmonary disease) is used for a number of conditions including chronic bronchitis and emphysema, which all lead to the airways in the lungs becoming damaged and thus narrower, making inhalation and exhalation harder...
