Effects of two protocols of intermittent hypoxia on human ventilatory, cardiovascular and cerebral responses to hypoxia
We determined the ventilatory, cardiovascular and cerebral tissue oxygen response to two
protocols of normobaric, isocapnic, intermittent hypoxia. Subjects (n= 18, male) were …

The interaction of carbon dioxide and hypoxia in the control of cerebral blood flow
A Mardimae, DY Balaban, MA Machina, JS Han… - … -European Journal of …, 2012 - Springer
Both hypoxia and carbon dioxide increase cerebral blood flow (CBF), and their effective
interaction is currently thought to be additive. Our objective was to test this hypothesis. Eight …
