This review highlights the influence of oxygen (O2) availability on cerebral blood flow (CBF).
Evidence for reductions in O2 content (CaO2) rather than arterial O2 tension (PaO2) as the …

A systematic meta-regression analysis of the effects of acute hypoxia on the performance of
central executive and non-executive tasks, and the effects of the moderating variables …

Acute hypobaric hypoxia (HH) is a major physiological threat during high-altitude flight and
operations. In military aviation, although hypoxia-related fatalities are rare, incidences are …

Background Hypoxia is a common occurrence following stroke and associated with poor
clinical and functional outcomes. Normal oxygen physiology is a finely controlled …

Quantitative measurements of brain perfusion are influenced by perfusion-modifiers.
Standardization of measurement conditions and correction for important modifiers is …

Abstract Ainslie, Philip N., and Andrew W. Subudhi. Invited Review: Cerebral blood flow at
high altitude. High Alt Med Biol. 15: 133–140, 2014.—This brief review traces the last 50 …

The interindividual variation in ventilatory acclimatization to high altitude is likely reflected in
variability in the cerebrovascular responses to high altitude, particularly between brain …

The aim of the present study was to examine changes in cerebral metabolism by magnetic
resonance imaging of healthy subjects during inhalation of 10% O2 hypoxic air. Hypoxic …

Acute exercise has been demonstrated to improve cognitive function. In contrast, severe
hypoxia can impair cognitive function. Hence, cognitive function during exercise under …

Rapid ascent to high altitude commonly results in acute mountain sickness, and on occasion
potentially fatal high-altitude cerebral edema. The exact pathophysiological mechanisms …
