Patients with acute neurologic injuries frequently require mechanical ventilation due to
diminished airway protective reflexes, cardiopulmonary failure secondary to neurologic …

Previous studies reported enhanced cerebrovascular CO2 reactivity upon ascent to high
altitude using linear models. However, there is evidence that this response may be …

BACKGROUND AND PURPOSE: Experienced freedivers can endure prolonged breath-
holds despite severe hypoxemia and are therefore ideal subjects to study apnea-induced …

The ability to maintain adequate cerebral blood flow and oxygenation determines tolerance
to central hypovolemia. We tested the hypothesis that acute hypoxemia during simulated …

The article discusses research being done on cerebral blood flow (CBF) regulation during
hypoxia. It examines a study by S. Ogoh and colleagues on the effect on blood flow of acute …

New Findings What is the central question of this study? Does the ventilatory response to
moderate acute hypoxia increase cerebral perfusion independently of changes in arterial …

Playing a musical instrument includes reading music scores, playing, and listening in
parallel. It is unclear which of these activities are responsible for an increase in cerebral …

Background β1 blockers increase the risk of cerebral hypoxia during acute anemia and
apneic hypoxia. We hypothesized that β1 stimulants conversely increase cerebral tolerance …

The purpose of the present study was to examine whether the response of cerebral blood
flow to an acute change in perfusion pressure is modified by an acute increase in central …

Acute exposure to hypoxia presents a unique challenge for the human brain, in particular
the NVU. Important for the integrity of the NVU is maintaining the delicate micro-environment …
