Rationale altitudes are, however, not entirely clear. Whether exercise at high altitude is
limited by ventilation, diffusion capacity, the pulmonary circulation or muscle energetic is …

The major risk factors for acute high altitude illnesses are the history of acute high altitude
illnesses on previous exposures, the altitude exposures in the weeks preceding the ascent …

They may suffer from severe acute mountain sickness, high altitude pulmonary or cerebral
edema, especially when they are not yet acclimatized to the hypoxic environment (Hackett et …

subjects at moderate altitude. Aviat Space Environ Med 2013; 84: 22–6. Background …

INTRODUCTION: Despite technological advances, hypoxia remains a concern in aviation.
Hypoxia can present with a vast array of symptoms that are unique to each aviator. Military …

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

Introduction: Annually, millions of people expose themselves to hypobaric hypoxia (HH)
while traveling to touristic mountain areas or by plane, among them patients with pulmonary …

PURPOSE: Respiratory events account for 5-15% of in-flight emergencies, representing the
second-commonest cause of in-flight death, and may be precipitated by hypoxemia. With …

Altitude travel results in acute variations of barometric pressure, which induce different
degrees of hypoxia, changing the gas contents in body tissues and cavities. Non ventilated …
